Embracing uncertainty<br />
It was Winston Churchill who said,<br />
“Without a measureless and perpetual<br />
uncertainty, the drama of human<br />
life would be destroyed.” Well, life is<br />
certainly interesting at the moment<br />
but, like most business owners, I’d<br />
probably settle for a little less drama<br />
and a little more certainty.<br />
If the recent drama involving the<br />
two women from the UK who drove<br />
to Wellington to see a dying relative,<br />
resulting in a litany of isolation<br />
breaches, teaches us anything, it’s<br />
that nothing is certain. But, as all<br />
the experts tell us, it’s also from<br />
uncertainty, especially in tough times,<br />
that we learn to adapt, to change,<br />
leading to better products and ways<br />
of doing business.<br />
One change we’ve introduced is our newly redesigned, now A4<br />
magazine. We hadn’t planned the change; it was made in response to NZ<br />
Post’s decision to alter its processes as it attempts to improve efficiencies<br />
in the pandemic’s wake. We hope you like it. We think it’s a good change<br />
that has other benefits too, for us, for our advertisers and for you, we<br />
hope, as we will now fit better into your bags and your hand.<br />
This is also the last month we’ll be providing the magazine free online as<br />
soon as it’s published, returning to our pre-pandemic subscription model,<br />
which we paused for three months to help us all get through. Without<br />
planning, David Slack discusses the plight of the media in this month’s<br />
The only certainty is that<br />
nothing is certain,<br />
Pliny the elder<br />
Experiencing the emotional ups and downs of uncertainty isn’t always a bad thing<br />
Chalkeyes presents (p38) and puts into<br />
words something we espouse, “…<br />
publications that speak to our interests<br />
and values, that cares about our<br />
community of interest, about you, are<br />
something to prize.” Thus, this month’s<br />
magazine, together with all the news<br />
and clinical learnings, continues to<br />
provide what we hope is a plethora of<br />
useful advice to support you and your<br />
businesses during these uncertain times.<br />
As David Pearson, our long-term<br />
financial commentator, writes in<br />
his Focus on Business column (p32)<br />
getting through successfully isn’t<br />
about making big leaps, “…it’s about<br />
incremental change: take a small step,<br />
reflect, learn, adjust and take another<br />
small step.”<br />
The last several weeks have been a bit of a roller coaster ride<br />
emotionally, and probably continues to be for many of us, but as Siu-<br />
Yin Shing says in this month’s Style Eyes (p34), developing a resilient,<br />
successful business is based on creating a positive, lasting impression<br />
among your target audience. Hopefully,<br />
that’s something we’re achieving. We<br />
welcome your feedback.<br />
All the best,<br />

Sharing her work into the limitations of the B4 School<br />
Check when it comes to our kids’ visual acuity (p10),<br />
Auckland University researcher Rebecca Findlay<br />
says she’s always been interested in science, and<br />
optometry was a great way to combine science with<br />
working with people. “I love that in my job and in my<br />
research, I have the opportunity to make a difference in<br />
kids’ lives in a very meaningful way by improving not only their vision but<br />
their potential to learn in the school environment.” When not working,<br />
she says she particularly enjoys spending time with her family, travelling<br />
(pandemics allowing) and getting creative with craft activities.<br />
Tracey Ellin<br />
Behind the scenes, beavering away to make your<br />
NZ Optics magazine look as beautiful as it does, is<br />
our own Tracey Ellin, who this month gets a special<br />
‘contributor’ mention for redesigning our magazine,<br />
at short notice, to a standard A4 format. This is the<br />
second time Tracey has redesigned the magazine<br />
as she was also responsible for changing our old, A3<br />
newspaper format into our much lauded (thank you!)<br />
more reader-friendly, magazine-style publication in mid-2018.<br />
Tracey is a former nurse who retrained as a graphic designer after her<br />
children started school. From the get-go she loved the process of making<br />
a magazine and being part of a small team, she says. Having worked for<br />
several interior and lifestyle magazines, she’s also expanded her design<br />
knowhow by completing Unitec’s interior design programme and working<br />
part-time for Auckland design store, The Ivy House. In her spare time,<br />
she’s kept busy upskilling her photography and video knowledge, making<br />
things, walking the dog, spending time with family and taking the odd<br />
adult ballet class. For rest, she says she loves a good film or book and<br />
reading magazines, preferably printed ones!<br />

Celebrating excellence despite Covid<br />
By Lesley Springall<br />
THE MUCH-ANTICIPATED<br />
Excellence in Ophthalmology<br />
and Vision Research Prize<br />
Evening may have been<br />
knocked back by the Covid-19<br />
pandemic, but the <strong>2020</strong><br />
awardees are still being<br />
recognised and will be invited<br />
to receive their awards at a<br />
special, celebratory event later<br />
this year.<br />
Professor Charles<br />
McGhee, chair and head<br />
of ophthalmology at the<br />
University of Auckland, said<br />
it’s been two years of upset for<br />
the awards unfortunately, with<br />
last year’s 20-year anniversary<br />
celebrations cancelled<br />
following the Christchurch terror attack. The<br />
awards still went ahead, but were a sombre<br />
event given the effect of the attacks on many at<br />
the university.<br />
But now a new event is being planned,<br />
“hopefully” in September, said Prof McGhee,<br />
to truly celebrate the excellence awards 23rd<br />
anniversary and the growth and success of the<br />
expanded department as it notches up its 21st.<br />
It will also celebrate all past award winners,<br />
including this year’s, he said. “We never<br />
envisaged the Department of Ophthalmology<br />
would grow so rapidly, nor the number of truly<br />
outstanding undergraduate and postgraduate<br />
research students that would pass through<br />
our hands, but this now numbers more than<br />
100, many of whom are now in national and<br />
international leadership roles.”<br />
Prof McGhee congratulated this year’s award<br />
winners who have all been notified. They were<br />
all very worthy recipients whose work and<br />
commitment to ophthalmology continues<br />
the strong legacy of the awards and the<br />
department, he said. “Year-on-year, the standard<br />
of our students increases exponentially and<br />
this year, many exhibit outstanding academic<br />
credentials alongside impressive sporting, music<br />
and other achievements. Indeed, it makes me<br />
glad I am not competing for a career as a young<br />
doctor in <strong>2020</strong> as I might struggle in such an<br />
exemplary epoch!”<br />
The Calvin Ring Prize – Shin Jee Tang<br />
The Calvin Ring Prize is awarded to the best<br />
all-round undergraduate medical student in<br />
clinical ophthalmology.<br />
This year’s award winner, Shin Jee Tang, is<br />
a final-year trainee intern at Waikato Hospital.<br />
She hopes to pursue a career in ophthalmology<br />
as it offers a good mix of both medicine and<br />
surgery, she said. “Winning the Calvin Ring Prize<br />
meant a lot to me as my effort, enthusiasm and<br />
passion in ophthalmology were recognised and<br />
Excellence in Ophthalmology <strong>2020</strong> awardees, Shin Jee Tang, Sunny Sixiao Li and Keli Matheos<br />
acknowledged. It further fortifies my love for<br />
this specialty and hopefully serves as a good<br />
steppingstone when I apply to join the training<br />
programme.”<br />
The William MacKenzie Medal –<br />
Sunny Sixiao Li<br />
Recognising the significant contribution made<br />
by a medical student or trainee intern towards<br />
a published research project, the William<br />
MacKenzie Medal was awarded to second-year,<br />
Auckland-based house officer Sunny Sixiao Li.<br />
Li’s research focused on corneal wound<br />
healing following cataract surgery, which<br />
resulted in a number of published studies.<br />
These included the validation of questionnaires<br />
for prioritisation of elective cataract surgery<br />
in New Zealand (The New Zealand Medical<br />
Journal); corneal biomechanical changes<br />
following cataract surgery (Clinical and<br />
Experimental Ophthalmology); and prediction<br />
of pseudophakic refractive error (Journal of<br />
Cataract and Refractive Surgery).<br />
Li said she was both honoured and humbled<br />
to join the illustrious list of past recipients of<br />
the Medal. “This would not have been possible<br />
without my supervisors, Dr James McKelvie<br />
and Dr Stuti Misra, who have encouraged and<br />
supported me endlessly with their wealth of<br />
experience and wisdom.” Also thanking Prof<br />
McGhee and the ophthalmology department,<br />
Li said she hopes to continue her work in eye<br />
research for some time to come.<br />
The Arthur Thomas Paterson<br />
Scholarship – Dr Kaliopy Matheos<br />
The <strong>2020</strong> Arthur Thomas Paterson Scholarship,<br />
designed to assist with overseas postgraduate<br />
training, was awarded to Dr Kaliopy Matheos.<br />
Dr Matheos began her fellowship training<br />
with the glaucoma team at the Greenlane<br />
Clinical Centre in Auckland before using the<br />
award to help her gain further experience as<br />
the glaucoma and anterior segment fellow<br />
at the University of Toronto in Canada. Her<br />
focus there was primarily on the management<br />
of complex glaucoma cases but included an<br />
interesting foray into the surgical management<br />
of ectopia lentis, she said.<br />
Winning the award was a huge honour, said<br />
Dr Matheos. “The scholarship meant I have<br />
been able to achieve many of the goals I set out<br />
to achieve when embarking on my fellowship<br />
training.”<br />

Eyes reveal true age<br />
BOSTON UNIVERSITY<br />
MEDICAL researchers<br />
have discovered a<br />
specialised eye scanner<br />
that accurately measures<br />
spectroscopic signals<br />
from proteins in the lens<br />
can also detect and track A/Prof Lee Goldstein<br />
biological aging.<br />
Chronological age does not adequately<br />
measure individual variation in the rate of<br />
biological aging, said study lead, Associate<br />
Professor Lee Goldstein. “The absence of<br />
clinical tools and metrics to quantitatively<br />
evaluate how each person is aging at<br />
the molecular level represents a major<br />
impediment to understanding aging and<br />
maximising health throughout life. The lens<br />
contains proteins that accumulate agingrelated<br />
changes throughout life. Our eye<br />
scanner can decode this record.”<br />
The study was published in the Journal of<br />
Gerontology: Biological Sciences.<br />

oDocs’ inaugural award winner<br />
INNOVATIVE EYE CARE technology enterprise oDocs Eye Care has<br />
awarded it’s first oDocs Project Grant Award to fifth year Otago medical<br />
student Aqeeda Singh.<br />
The new $5,000 award is designed to promote sight saving initiatives<br />
and innovative research projects by medical students and residents, fellows<br />
and researchers in the field of ophthalmology, said oDocs founder and<br />
ophthalmology registrar Dr Sheng Chiong Hong.<br />
Singh was chosen as the inaugural recipient of the new award given her<br />
continuous achievement over the past year and the number of high-quality<br />
research papers she’s published, he said. “Her tenacity and hard work in<br />
ophthalmic science and research made her an outstanding candidate.”<br />
Singh is using the grant to continue her work into creating guidelines<br />
for acute ophthalmic conditions that present in primary care, creating a<br />
protocol for non-eye specialists as part of a bigger teleophthalmology<br />
project with oDocs’ sister company MedicMind. “This will help simplify<br />
the management for clinicians hopefully,” she said. “The project is also<br />
giving me a chance to satiate my eagerness to learn more about eyes!”<br />
Singh said she’s keen to continue her journey in ophthalmology when<br />
she graduates. “As a child, I used to say the eyes were my favourite body<br />
part and it hasn’t really changed… However, almost every consultant has<br />
advised us to remain flexible and keep our minds open!”<br />
Thanking Dr Hong and her senior lecturer Dr Kelechi Ogbuehi, she said<br />
she owes a great deal to their support and “encouraging nature” to have<br />
got to where she is today. “I couldn’t have asked for better supervisors.”<br />
The oDocs Project Grant Award will initially be awarded annually, but<br />
the plan is to increase this, said Dr Hong. Award winners are selected<br />
by Drs Hong, Ogbuehi and, oDocs co-founder, Ben O’Keeffe after being<br />

A RECENT AUSTRALIAN survey<br />
has found many parents are<br />
shocked to learn their children<br />
have vision problems and struggle<br />
with a range of issues and<br />
emotions at the time of diagnosis<br />
and during treatment.<br />
The Little Aussie Eyes Report<br />
by Kids Eye Gear surveyed 450<br />
Australian parents of children with<br />
vision issues to provide insight<br />
into their concerns, said Nicola<br />
Rivett, Kids Eye Gear founder and<br />
mother of a son who required<br />
patching due to congenital<br />
cataract and subsequent surgery.<br />
“Noticing that your child has a<br />
vision problem is not always easy.<br />
Kids don’t know that what they see<br />
isn’t ‘normal’. They learn to adapt to<br />
what sight they have and parents<br />
can be completely unaware there is<br />
an underlying issue.”<br />
Consequently, many parents<br />
are shocked to find out their child<br />
has a vision problem, she said,<br />
describing feelings of guilt, being<br />
overwhelmed and recalling the<br />
diagnosis as a very emotional<br />
experience. “I was actually very sad<br />
and emotional,” one respondent<br />
to the survey said while another<br />
said they were “shocked, confused,<br />
worried and overwhelmed”.<br />
The majority of parents<br />
surveyed had children who wear<br />
prescription glasses (81%), with<br />
70% diagnosed between the ages<br />
of two and five. The three main<br />
challenges parents identified with<br />
kids and glasses were: keeping<br />
glasses clean (62%); finding<br />
frames that fit (43%); and finding<br />
affordable glasses (41%).<br />
Of those surveyed, 82% had<br />
experience of patching, with one in<br />
four of their children<br />
prescribed at age<br />
four and just over<br />
half (53%) prescribed<br />
between two and<br />
five. The main reason<br />
for patching was<br />
amblyopia (60%).<br />
By far the<br />
Nicola Rivett<br />
biggest challenge<br />
with patching, identified by<br />
parents, was getting the child<br />
to actually wear the patch in the<br />
first instance (65%), followed by<br />
finding affordable patches (43%)<br />
and patches that didn’t irritate<br />
the child’s skin (30%), and fitting<br />
in the required patch time in<br />
their daily lives (30%). As many<br />
as 58% of parents surveyed said<br />
it was stressful having to patch<br />
their child. Though many said<br />
establishing a routine helped, with<br />
51% preferring to patch in the<br />
morning while providing close-up<br />
activities for the child, such as<br />
iPad/tablet, television, playing<br />
with toys or doing crafts.<br />
Commenting on the report,<br />
Rivett said she has “huge” respect<br />
for eye health professionals and<br />
hoped the findings<br />
will encourage<br />
them to continue<br />
advocating for early<br />
vision screening and<br />
providing exceptional<br />
care.<br />
“As the study<br />
showed, many<br />
parents experience<br />
feelings of surprise, shock and<br />
guilt when their young one is<br />
diagnosed with a vision problem.<br />
If eye care professionals can be<br />
empathetic to these feelings and<br />
equip parents with resources to<br />
understand their child’s condition,<br />
or at least point them in the<br />
right direction for additional<br />
information, this will help alleviate<br />
any initial negative feelings or<br />
fear about the diagnosis. I believe<br />
this would create increased<br />
positive outcomes for the child’s<br />
vision and further strengthen the<br />
practitioner/patient relationship.”<br />

RESEARCH<br />
Worrying results from WTS study<br />
By Rebecca Findlay<br />
UNCORRECTED REFRACTIVE ERRORS<br />
account for up to 96% of visual impairment<br />
in school-aged children and are<br />
associated with amblyopia and strabismus<br />
development, and reduced performance<br />
in early literacy tests, reading ability<br />
and academic achievement. Amblyopia<br />
treatment is most effective before seven<br />
years of age, thus, it’s important to identify<br />
children with amblyopia risk factors at a<br />
young age.<br />
Preschool children in New Zealand<br />
receive a universal, free, well-child check,<br />
the B4 School Check (B4SC), at four-yearsold<br />
to identify behavioural, developmental<br />
and other health concerns which could<br />
negatively impact their ability to learn. The<br />
B4SC has excellent coverage, with 96.7%<br />
of eligible children and 94.5% of children<br />
living in high deprivation communities in<br />
the Auckland region, completing the check<br />
in 2017. As part of the B4SC, children’s<br />
visual acuity (VA) is screened using the Parr<br />
vision chart, specifically to identify children<br />
with amblyopia. Distance VA measurement<br />
is more effective for myopia detection than<br />
hyperopia and astigmatism. There are currently<br />
no contemporary refractive error data for New<br />
Zealand children and it’s unknown whether<br />
ethnic differences exist, particularly for Māori<br />
and Pacific children.<br />
The study<br />
The Welcome to School (WTS) study was<br />
a multidisciplinary, collaborative study of<br />
children from schools in the Manaiakalani<br />
Community of Learning in Tāmaki: the<br />
Auckland suburbs of Glen Innes, Point England<br />
and Panmure.<br />
The aims of the study were to determine<br />
the prevalence of refractive error and visual<br />
impairment in a cohort of six to seven-year-old<br />
children and evaluate the efficacy of the B4SC<br />
programme in the multicultural community of<br />
Tāmaki, where the majority of children are of<br />
Māori or Pacific ethnicities.<br />
Coffee’s surgery impact<br />
Children were recruited on school entry<br />
and received a comprehensive health,<br />
developmental and social assessment. These<br />
same children and whānau were contacted by<br />
the WTS research nurse approximately one year<br />
later at six to seven years of age. 114 children<br />
received a comprehensive cycloplegic vision<br />
examination in their schools.<br />
Results<br />
Almost one third (31.6%) of participants had<br />
significant refractive error, of which 80.6% was<br />
astigmatism. Myopia prevalence was low (3.5%)<br />
and seven participants (6.1%) had amblyopia<br />
risk factors. The B4SC vision screening was<br />
effective in detecting amblyopia, with no<br />
child with amblyopia risk factors passing the<br />
screening. Though a significant number of<br />
children (11.4%) did not receive a B4SC vision<br />
screening and a similar number (10.5%) were<br />
identified for B4SC rescreening which had not<br />
been completed. Both included children with<br />
amblyopia risk factors.<br />
The B4SC was ineffective, however, at<br />

alone or a β-blocker and caffeine combination on the surgical<br />
performance of 15 VR surgeons with less than two years surgical<br />
experience.<br />
Propranolol alone was associated with improved surgical<br />
performance compared with caffeine alone and the combination of caffeine and propranolol,<br />
suggesting caffeine negatively affects surgical performance. “These results may be helpful for<br />
novice vitreoretinal surgeons to improve microsurgical performance,” said the authors.<br />
detecting significant refractive error with<br />
more than half the children with significant<br />
refractive error passing. Only 13.9% of<br />
children with significant refractive error<br />
and 57.1% with amblyopia risk factors were<br />
wearing glasses at the time of assessment.<br />
Nearly 60% of children with significant<br />
refractive error passed the screening and<br />
none were wearing glasses, suggesting<br />
children who passed were unlikely to have<br />
had a comprehensive eye examination<br />
which would have detected mild to<br />
moderate uncorrected refractive error.<br />
Consequently, many children in this cohort<br />
started school with uncorrected refractive<br />
errors potentially impacting their academic<br />
performance.<br />
Recommendations<br />
There is currently a mismatch between the<br />
aims of the vision screening programme,<br />
which is targeted at detecting amblyopia,<br />
and the overall B4SC which aims to detect<br />
and intervene on issues which could adversely<br />
impact educational outcomes, particularly for<br />
socioeconomically disadvantaged Māori and<br />
Pacific children. This mismatch, in combination<br />
with the differential reach of the B4SC, is likely<br />
to be increasing inequities.<br />
This study suggests urgent attention is<br />
required to review the B4SC vision screening<br />
protocol to ensure it is appropriate and<br />
equitable, so all children receive high quality<br />
vision screening and eye care to improve<br />
their health, educational and social outcomes.<br />
Alternative screening strategies may be more<br />
appropriate to detect refractive error. A review<br />
of the Well Child Tamariki Ora programme<br />
is currently underway and provides an<br />
opportunity to re-examine the rationale for<br />
preschool vision screening and follow-up<br />
protocol. While eligible children can receive the<br />
Enable subsidy for glasses, the process can be<br />
difficult for families to navigate. Cost should<br />
not be a barrier. Eye care services should be<br />
available for all children. Culturally appropriate<br />
coordination is necessary to ensure children<br />
who are referred or identified for rescreening<br />
receive follow up and are assisted in accessing<br />
services.<br />

The post-Covid<br />
shopping street<br />
By Jai Breitnauer<br />
NEW ZEALAND HAS fared well globally in<br />
the fight against Covid-19, but it has not been<br />
without cost. It is only now the smoke is clearing<br />
enough to see how the pandemic has affected<br />
our main shopping thoroughfares and what<br />
impact that may have on optometry practices.<br />
Thankfully, the big picture is looking much<br />
better than expected. With a fiscal stimulus<br />
package amounting to $62.1bn mixed with<br />
quantitative easing and a low interest rate,<br />
we’ve seen commentators roll back on their<br />
dire predictions. Indeed, figures from early<br />
June show retail spending is down just 2% on<br />
last year, with The Bank of New Zealand now<br />
predicting GDP will return to pre-Covid levels<br />
by mid-2022, rather than the fourth quarter<br />
of 2023 as previously suggested. However,<br />
a recent Euromonitor International report<br />
suggests globally, real economic growth will be<br />
at its lowest this year since 1961, so there’s no<br />
room to be complacent.<br />
Complacency is one path Andrew Judd<br />
could not afford to take. The owner of New<br />
Plymouth-based Judd Opticians said they used<br />
their time in level 4 lockdown to evaluate their<br />
business model.<br />
“The week prior to lockdown we were<br />
already starting to be impacted by Covid-19,<br />
mostly in a reduction of forward appointments<br />
and foot traffic,” Judd said. “Obviously, going<br />
The need for<br />
eyewear hasn’t gone<br />
away. Use social<br />
media to promote<br />
your business in a<br />
gentle way<br />
into level 4 the impact was immediate. We<br />
used the time to evaluate and plan what postlockdown<br />
could look like. Fundamentally what<br />
we do remains, but it’s how we now do it.”<br />
Increased online power<br />
Judd identified that for his business, one<br />
key area of deficit was online, and with the<br />
Euromonitor report suggesting e-commerce<br />
retailers are one of the four types of retail<br />
business that will fare best through this crisis,<br />
that doesn’t seem like a bad place to start.<br />
“We researched all available business<br />
support and secured regional development<br />
funding towards upgrading our online activity.<br />
We also reached out to surrounding businesses<br />
to jointly promote on social media,” said Judd,<br />
adding the joint online promotion had an<br />
immediate positive impact on his business.<br />
Daniel Feldman, a founding member of<br />
The Visionaries Group in the US and owner<br />
of the Optical Journal podcast, said in a recent<br />
instalment of his show that if businesses aren’t<br />
advertising, he doesn’t know how they are<br />
staying afloat.<br />
“You Tube have stopped optimising their<br />
videos to save on bandwidth, a recognition<br />
of the amount of time people are spending<br />
online,” he said. “The reach I am getting in<br />
Google ads is three to four times what I was<br />
getting in February. Everyone has stopped<br />

FEATURE<br />
advertising, so I am not competing for eyeballs<br />
as I was before. The need for eyewear hasn’t<br />
gone away. Use social media to promote your<br />
business in a gentle way.”<br />
New Zealand retail consultant Chris<br />
Wilkinson agreed for reaching consumers<br />
online sales and advertising activity is of<br />
greater importance right now.<br />
“There is likely to be less footfall as we<br />
come out of this as consumer behaviour<br />
changes with more ‘purposeful’ journeys, less<br />
browsing and, consequentially, fewer impulse<br />
sales opportunities. More transactions will<br />
likely start online as people browse ranges<br />
and availability but still, the majority will end<br />
in store. This means that businesses need to<br />
redouble efforts around their online profile<br />
and user experience.”<br />
Doubling efforts in-store<br />
User experience in-store is another essential<br />
area optometry businesses need to be working<br />
on as things ramp up, continued Wilkinson.<br />
“Trust, welcome and recognition will be<br />
even more vital as we come out of the Covid<br />
environment. There is already trepidation<br />
from consumers about medical environments,<br />
so any situation which relies on one-on-one<br />
interactions needs extra reassurance and<br />
confidence.”<br />
Lisa Donaldson of Retail X consultancy<br />
said business owners should plan out their<br />
physical stores in line with social distancing<br />
measures, but with user experience at the<br />
forefront of their<br />
mind.*<br />
“Walk your<br />
store as a shopper<br />
would to assess<br />
how your current<br />
environment meets<br />
the recommended<br />
health<br />
requirements.<br />
What can you do<br />
to improve the flow<br />
of shoppers in your<br />
space?”<br />
Katrina Hammon: look at<br />
local marketing<br />
Donaldson<br />
recommended<br />
freeing up space<br />
where you can,<br />
especially in the ‘landing zone’ at the front<br />
of your practice, by removing displays. “You<br />
might have to adapt to trade with less product<br />
on the floor. To support this, you may need<br />
to reorganise storage space, replenish your<br />
product displays more frequently or present<br />
your product in new ways.<br />
“Engage with shoppers through<br />
How will shoppers’ habits change post-Covid?<br />
meaningful, well-thought-out displays and<br />
storytelling – not just loads of product on a<br />
stand.”<br />
Solicitor Katrina Hammon, a franchise<br />
specialist and partner at Wynn Williams in<br />
Christchurch, said she believes that franchise<br />
opportunities may become more desirable in<br />
this new post-Covid climate, offering greater<br />
security to franchise holders.<br />
“The larger, corporate-owned or franchised<br />
networks have been ramping up their<br />
digital marketing and pushing online sales.<br />
Larger competitors will also be leveraging<br />
relationships and special offers to gain more<br />
market share and exploit additional channels<br />
to market to these potential new patients.”<br />
Hammon said it is a big decision, but<br />
if you are now considering a franchise<br />
opportunity, make sure you understand the<br />
fees and exit payments, and complete your<br />
own due diligence. Also look at what help the<br />
franchisor can offer with rent on premises,<br />
especially if you can’t trade.<br />
Consider local marketing initiatives<br />
For those flying solo, she also has good advice.<br />
“[Smaller businesses should] look at local<br />
marketing opportunities… local papers or<br />
radio advertising… building partnerships<br />
and relationships with aged-care facilities,<br />
industry associations, business groups and<br />
even larger businesses may be an option.<br />
Given the diverse population in New Zealand,<br />
it is also sound advice to consider if you could<br />
better market to different ethnic groups. For<br />
example, have advertisements translated for<br />
The Indian News, Chinese Herald or Home<br />
Voice Chinese Newspaper. Your employees<br />
should take the time to understand crosscultural<br />
communication and focus on the<br />
experience being welcoming for all.”<br />
Andrew Judd said<br />
this post-Covid retail<br />
landscape actually<br />
presents some<br />
good opportunities<br />
for independent<br />
optometrists given<br />
their business model<br />
is based on longstanding<br />
patients and<br />
building trust.<br />
“These changing<br />
times offer an<br />
exciting opportunity Andrew Judd: consider<br />
for private practice joint, online promotions<br />
to re-establish the<br />
narrative of our<br />
profession. As a dispensing optician who<br />
qualified with the skills of edging and fitting,<br />
frame repairs and adjustments, I was called<br />
upon over level 4 and level 3 to use those skills<br />
to assist frontline workers. I mention this to<br />
remind our profession that we have many<br />
aspects to patient care. It is the practice that<br />
builds long-term trust and service that will<br />
remain and grow.”<br />

MyHealth1st launches managed<br />
advertising services<br />
By 1st Group<br />
THE COVID-19 PANDEMIC has, to put it mildly,<br />
made things hard for businesses across New<br />
Zealand. Even with lockdown restrictions being<br />
eased and the world slowly returning to the<br />
new normal, consumer confidence is low, so<br />
making sure patients return to your practice<br />
is vital, not only for the financial wellbeing of<br />
your practice but for the eye health of your<br />
patients as well.<br />
Since 1stGroup launched MyHealth1st in<br />
2012, it has been dedicated to one mission –<br />
making it simple for patients to connect with<br />
practices to get the healthcare they need in<br />
a timely and effective manner. This mission<br />
statement drives all our efforts, from how<br />
we consistently improve our online booking<br />
process to the launch and support of new<br />
products and services. As such, expanding<br />
into helping practices succeed through digital<br />
advertising was a necessary step to ensure our<br />
goal of connecting patients with the eye health<br />
services they need.<br />
At MyHealth1st, we understand the<br />
challenges that come with running an<br />
independent optometry practice because we<br />
work with thousands of practices just like yours,<br />
right around New Zealand and Australia. It’s<br />
because of this understanding of the needs of<br />
independent practices that we have developed<br />
our managed advertising service.<br />
So what exactly are we offering? We will<br />
provide managed Google and social media<br />
advertising campaigns for all practices, with<br />
packages and offers being individually tailored<br />
to meet the needs of single practices and<br />
chains alike. Google advertising, an active<br />
social media presence and well targeted social<br />
Covid-19 breathalyser<br />
media advertising on Facebook and Instagram<br />
are of vital importance when it comes to<br />
increasing the visibility of any practice.<br />
An effectively managed Google advertising<br />
plan can help you climb to the top of search<br />
engine rankings, so you can reach more<br />
patients at every stage of the booking funnel,<br />
from patients researching symptoms to<br />
making the decision, to actively booking<br />
an appointment for an eye test, glasses or<br />
contact lens fitting or other consult. Our<br />
team has extensive experience planning,<br />
OHIO STATE UNIVERSITY researchers are testing a new breathalyser that could act as a cheap,<br />
quick and more patient-friendly test for Covid-19 compared with the current deep nasal swab.<br />
The new project builds on primary investigator Professor Perena Gouma’s invention of a<br />
hand-held breath monitor for the early detection of flu. The sensor detects nitric oxide and<br />
volatile organic compounds from a person’s breath, which can indicate the onset of an infectious<br />
disease. Testing for this has now been expanded to two other metabolites that can reveal if a<br />
person is infected with Covid-19, even if they’re<br />
asymptomatic, she said. “Exhaling once in the<br />
breathalyser may help with earlier detection of<br />
the onset of the disease, as well as monitoring<br />
the severity of infection… allowing more timely<br />
therapeutic intervention.”<br />
If proved accurate, the breathalyser could become<br />
a key diagnosis platform for a range of metabolic<br />
diseases such as cancer, Alzheimer’s or diabetes,<br />
by simply choosing the appropriate biomarker to<br />
sample, said Prof Gouma adding it will also allow for<br />
mass screening at airports or other gatherings.<br />
Prof Perena Gouma with the prototype<br />
implementing and managing successful and<br />
cost-effective Google AdWords campaigns. We<br />
want to drive new patients to optical practices<br />
and a managed Google advertising service<br />
allows practices to monitor and measure the<br />
advertising spend and return on investment for<br />
each campaign.<br />
A social media presence is vital, but there’s<br />
no point in putting money or effort into ads<br />
if they’re not being seen by the right people<br />
or the messaging is wrong. Managed social<br />
media advertising can plan and roll out<br />
campaigns across Facebook, Instagram and<br />
LinkedIn and help practices reach the right<br />
people in the right areas to help you achieve<br />
your goals.<br />
With a tailored Google and social media<br />
marketing campaign, you will be able to<br />
reach more patients in your area as well as<br />
re-engage with existing patients that may have<br />
been putting off visiting your practice due to<br />
Covid-19 fears. With our tailored, managed<br />
advertising services your messaging will be<br />
unique to your practice, speaking directly<br />
to your market, speeding your recovery<br />
after this time of economic uncertainty<br />
and differentiating your practice from your<br />
competitors.<br />

Vision therapy inspired by bats<br />
EUROPEAN SCIENTISTS HAVE developed a new therapeutic approach<br />
based on gene therapy, that could provide a new form of sight to<br />
patients suffering from degenerative eye diseases such as macular<br />
degeneration (MD) and retinitis pigmentosa (RP).<br />
MD and RP are caused by the degeneration of photoreceptors.<br />
Researchers from the Institute of Molecular and Clinical Ophthalmology<br />
Basel and the German Leibniz Institute for Primate Research (DPZ)<br />
successfully re-activated degenerated photoreceptors allowing animal<br />
models to see infrared heat signatures without negatively affecting<br />
remaining vision.<br />
The team were inspired by bats and snakes which use infrared heat<br />
signatures alongside typical vision to hunt prey. This enables bats and<br />
snakes to superimpose thermal and visual images in the brain and thus<br />
react to their environment with greater precision. To replicate this, the team<br />
developed a three-component system. The first element was engineered<br />
DNA, ensuring gene coding for the heat-sensitive channel is only expressed<br />
in photoreceptors; the<br />
second, a gold nanorod<br />
that efficiently absorbs<br />
near-infrared light; and<br />
the third, an antibody<br />
to bind the first two<br />
together.<br />
Trialling the system<br />
on mice with retinal<br />
degeneration, the<br />
team confirmed nearinfrared<br />
light effectively excited the photoreceptors and the signal was<br />
transmitted to the higher visual centres in the brain. Encouraged by this,<br />
co-author, Assistant Professor Arnold Szabo from Semmelweis University<br />
in Hungary, tested the model on cultured human retinas, successfully<br />
reactivating their visual circuitry. The study was published in Science.<br />

THE FINAL REPORT on the<br />
government’s long-awaited Health<br />
and Disability System Review<br />
confirmed New Zealand’s health<br />
services and workforce are under<br />
considerable stress and the health<br />
system is complex and fragmented.<br />
Though our system is better than<br />
many, the review sets out a path<br />
towards a better, more sustainable<br />
health system with clear lines of<br />
accountability, said health minister<br />
Dr David Clark. “One that is more<br />
responsive to the needs of local<br />
communities.”<br />
Chaired by health economist<br />
Heather Simpson, the review’s<br />
recommendations include:<br />

population health<br />
l Creating a new crown entity,<br />
provisionally called Health NZ,<br />
focused on operational delivery of<br />
health and disability services and<br />

Primary retinal telangiectasia<br />
By Dr Shanu Subbiah<br />
PRIMARY OR CONGENITAL<br />
retinal telangiectasia, more<br />
commonly called Coats’ disease<br />
or Coats’ syndrome, is a nonhereditary,<br />
developmental, retinal<br />
vascular disorder characterised<br />
by dilatation and exudation of<br />
the retinal vasculature, and an<br />
important cause of leucocoria in<br />
children.<br />
Case report<br />
A 13-year-old boy attended the<br />
emergency eye clinic with a oneday<br />
history of sudden onset loss<br />
of superior field of vision affecting<br />
his right eye. He had been<br />
trampolining the previous day.<br />
There was no history of trauma,<br />
photopsia or floaters. He had no<br />
past ocular history and was in<br />
good general health. He was not<br />
premature and had achieved all<br />
developmental milestones.<br />
On examination, visual acuity<br />
was 6/24+1 right and 6/4 left.<br />
He had a relative afferent pupil<br />
defect in his right eye. He was<br />
orthotropic on cover testing.<br />
Anterior segment examination<br />
was normal. Dilated fundal<br />
examination of his right eye<br />
revealed marked intraretinal<br />
exudation with an inferior<br />
non-rhegmatogenous retinal<br />
detachment and multiple large<br />
telangiectatic vessels with light<br />
bulb-shaped aneurysms (Fig<br />
1 and 2). The left retina was<br />
normal. Indirect indentation<br />
ophthalmoscopy of his right<br />
retina did not reveal any<br />
peripheral retinal tears. Ocular<br />
ultrasound revealed no posterior<br />
segment mass. A provisional<br />
diagnosis of Coats’ disease was<br />
made. Baseline bloods, including<br />
autoimmune and infective panels,<br />
were all normal. Both parents<br />
underwent fundal examination<br />
which was normal.<br />
Considering the patient was<br />
very cooperative, Argon focal<br />
laser was carried out directly to<br />
the telangiectatic vessels in the<br />
right eye. The patient was seen<br />
two weeks later for further focal<br />
laser. A large degree of the exudate<br />
had resorbed with a reduction in<br />
the size of the detachment (Fig<br />
3). Visual acuity had improved to<br />
6/9-2. The patient had a further<br />
final episode of focal laser three<br />
weeks later. Visual acuity improved<br />
and has been maintained at 6/6 in<br />
this eye. Twelve months later the<br />
macula remains flat with peripheral<br />
subretinal fibrosis (Fig 4). There has<br />
been no reoccurrence of subretinal<br />
fluid or exudation.<br />
History<br />
In 1908, George Coats described<br />
“exudative retinitis,” which<br />
was best characterised as<br />
vascular abnormalities with<br />
massive subretinal exudation 1 .<br />
Today, congenital or primary<br />
telangiectasia goes by his name,<br />
Coats’ disease. It consists of<br />
dilated retinal capillaries, microand<br />
macroaneurysms, ischemia,<br />
nonperfusion and retinal vascular<br />
leakage. It typically presents<br />
unilaterally in males.<br />
Four years later, Theodor Leber<br />
described “miliary aneurysms 2 ,”<br />
which were quite similar clinically<br />
to the cases seen by Coats.<br />
The term retinal telangiectasis<br />
was coined by the paediatric<br />
ophthalmologist Algernon Reese<br />
in 1956. He suggested that<br />

aneurysms were one and the<br />
same, occurring either in child or<br />
adulthood 3 .<br />
In 1968, Donald Gass described<br />
a new distinct entity which he<br />
called idiopathic juxtafoveolar<br />
retinal telangiectasis to<br />
differentiate it from Coats’<br />
disease. This resulted in a detailed<br />
classification of all telangiectatic<br />
diseases in 1993 4 .<br />
By 2006, Lawrence Yannuzzi,<br />
using new imaging systems such<br />
as optical coherence tomography<br />
(OCT) and high-speed stereo<br />
angiography, simplified<br />
telangiectasias classification<br />
into two distinct types: Type I,<br />
aneurysmal telangiectasia (Coats’<br />
disease); and Type II, perifoveal<br />
telangiectasia 5 . Now when we<br />
refer to macula telangiectasia or<br />
MacTel, we are often talking about<br />
the common bilateral disease<br />
(Type II) that we see in middleaged<br />
patients.<br />
Aetiology<br />
Coats’ disease is a non-hereditary<br />
ocular disease. The exact<br />
underlying mechanism remains<br />
unknown but a mutation of the<br />
norrin disease protein (NDP) gene<br />
has been proposed 6 , as this results<br />
in a deficiency of the protein<br />
norrin which regulates vascular<br />
development in the developing<br />
retina.<br />
The pathophysiological<br />
processes of Coats’ disease include<br />
the breakdown of the blood-retina<br />
barrier at the level of the vascular<br />
endothelium, predominantly<br />
affecting the capillaries but often<br />
with focal arterial involvement.<br />
Subsequent leakage leads to<br />
aneurysm formation and vessel<br />
blockage with exudation of blood,<br />
lipid and fibrin into the intra<br />
and subretinal spaces 7 . Vascular<br />
endothelial growth factor (VEGF),<br />
which plays an important role in<br />
the formation of normal retinal<br />
vessels and vascular permeability,<br />
is also elevated 8 .<br />
The end result is exudative<br />
retinal detachment. Chronic<br />
detachment can involve the<br />
anterior segment secondarily and<br />
lead to neovascular glaucoma and<br />
blindness 9 .<br />

NEUROTECH AND ARTIFICIAL<br />
intelligence start-up C Light has<br />
developed a non-invasive, fast<br />
and objective retinal eye-tracking<br />
technology to help doctors<br />
quickly and more accurately<br />
diagnose neurological conditions,<br />
such as multiple sclerosis (MS).<br />
Based at the University<br />
of California Berkeley’s tech<br />
incubator, the company was<br />
formed around a tracking<br />
scanning laser ophthalmoscope<br />
(TSLO) developed by C Light cofounder<br />
Dr Christy Sheehy. The<br />
TSLO technology measures the<br />
motion of the eye on a cellular<br />
scale; movements as small as<br />
1/100 the size of human hair.<br />
“The back of your eye is actually<br />
the front of your brain. We use<br />
AI paired with eye tracking to<br />
create a digital fingerprint of<br />
your neurological health with<br />
unprecedented speed and<br />
sensitivity,” said co-founder Dr<br />
Zachary Helft. “Other technologies<br />
use the pupil to track eye motion,<br />
Dr Zachary Helft<br />
but our technique images<br />
the retina for 120 times more<br />
sensitivity… C Light measures eye<br />
motion that has been otherwise<br />
invisible through existing pupil<br />
tracking technologies.”<br />
In this era of digital health, C<br />
Light is creating a completely new<br />
data stream about the status of<br />
brain health via the eye, said Dr<br />
Sheehy. “Our growing databases<br />
and accompanying AI can change<br />
the way we monitor and treat all<br />
neurological diseases for future<br />
generations.”<br />
Patients can be tested in<br />
10 seconds, are free to blink<br />
and don’t require eye drops or<br />
dilation, said Dr Sheehy. Though<br />
testing has begun with MS,<br />
future applications can extend<br />
to Alzheimer’s, Parkinson’s,<br />
Amyotrophic lateral sclerosis (ALS)<br />
and concussions, she added.<br />

Art and optics:<br />
The beautiful and the curious<br />
By Susanne Bradley<br />
In the artist’s self-portrait as Saint Lucy, patron of sight, the eyes on a plate<br />
have been replaced with the medication that cured da Silva from acute<br />
diplopia<br />
(Left) da Silva’s glass eyes were inspired by the museum’s diseased eye<br />
models. The double pupil represents her experience of double vision<br />
THE BRITISH OPTICAL<br />
Association Museum’s<br />
latest exhibition,<br />
Pathos Ocularis – The<br />
Beautiful and the<br />
Curious, was inspired<br />
by artist Iluá Hauck da<br />
Silva’s own experience<br />
of dry eye, diplopia<br />
and photophobia.<br />
Brazilian-born da<br />
Silva, the museum’s<br />
third artist-inresidence,<br />
is an artist<br />
and glassmaker<br />
who specialises<br />
in anatomical<br />
and pathological<br />
symbolism. Drawing<br />
inspiration from her<br />
personal experiences,<br />
the museum’s<br />
collections and from<br />
Iluá Hauck da Silva<br />
medical, scientific and<br />
historical research<br />
conducted in the College of Optometrists’ library, da Silva’s exhibition<br />
creates a modern-day ‘cabinet of curiosities’ dedicated to eyes.<br />
Her residency at the museum resulted when a collector friend<br />
commissioned an eye sculpture, she said. “I thought I’d go to the British<br />
Optical Association Museum, which I had been meaning to visit for<br />
quite some time, to look at eye models and get inspired. My friend and I<br />
booked an appointment with curator Neil Handley and during our visit…<br />
Neil asked to see my work and immediately asked me if I wanted to<br />
exhibit there, which I was delighted about!”<br />
Conceptually, da Silva said her art focuses on the human condition<br />
with body parts and internal organs featuring heavily in her work.<br />
“Growing up in Brazil as the daughter of a doctor, I spent countless time<br />
in hospitals and practices… I have always had an interest in the depiction<br />
of medicine,” she said in the podcast, Through the eyes of an artist.<br />
Developing work about ocular pathology felt particularly pertinent,<br />
said da Silva, as she developed sixth nerve palsy and acute diplopia in<br />
2015, after contracting a severe ear infection which spread. Her residency<br />
and this exhibition offered da Silva an opportunity to creatively explore<br />
eye dryness and photophobia, conditions she still suffers as a result of her<br />
illness. “Creating art that raises awareness of (these conditions), as well<br />
as how to prevent and soothe their symptoms, is not only relevant, but<br />
important to the general public.”<br />
Although the exhibition is a story of recovery, da Silva wanted to<br />
include the word ‘pathos’ in the title as in many cultures it “evokes<br />
suffering and pain, thus prompting empathy and compassion in the<br />
viewer for the sufferer,” she said.<br />
The British Optical Association Museum at the College of Optometrists<br />
in London was founded in 1901. It is the oldest optical museum in the<br />
world with a collection of more than 28,000 items. The Pathos Ocularis<br />
exhibition has been extended due to Covid-19 and will be available to<br />
visit by appointment for a minimum of six weeks once current restrictions<br />
have been lifted in the UK.<br />

US MEDICAL START-UP Rebion has<br />
developed a handheld paediatric vision<br />
scanner to help clinicians screen for<br />
amblyopia.<br />
The Blinq scanner can detect even<br />
subtle strabismus, said inventor Dr David<br />
Hunter, head of ophthalmology at Boston<br />
Children’s Hospital and co-founder of<br />
Rebion. “It can help facilitate earlier<br />
identification of children who need visionsaving<br />
treatment when therapy is likely to<br />
be more effective and reduce unnecessary<br />
referrals to ophthalmologists.”<br />
Dr Hunter and co-inventor Dr<br />
David Guyton, professor of paediatric<br />
ophthalmology at Johns Hopkins Hospital, said eye charts work well for<br />
six-to-seven-year-olds and some five-year-olds but detect amblyopia too<br />
late to fully treat. “Though photo screeners help identify more children at<br />
risk of amblyopia, their accuracy is limited by low detection of strabismus<br />
and high false positive rates,” said Dr Hunter.<br />
Using a polarised laser scan to probe the nerve fibres inside the retina,<br />
Blinq can detect a 1° misalignment between foveas, a sign amblyopia is<br />
present, he explained. “When detected with precision, misalignment of<br />
the foveas identifies essentially 100% of children who have amblyopia,<br />
with fewer false positives compared with photo screeners.” The scanner<br />
also calculates a binocularity score indicating whether a child requires<br />
referral to an ophthalmologist for further investigation.<br />
Two separate studies supporting Blinq’s effectiveness were presented<br />
at the American Academy of Ophthalmology. One, including 80 children,<br />
found Blinq offered 100% accuracy and a false referral rate of just 3%.<br />

US-BASED OPHTHALMIC device manufacturer BVI has launched<br />
CryoTreq, a single-use, handheld cryo-surgery device it claims will<br />
“revolutionise” retinal tear and detachment treatment.<br />
Developed in partnership with Professor Stanislao Rizzo, a retinal<br />
surgeon with the University of Florence, the CryoTreq functions<br />
without external connections to other equipment, gas tanks or power<br />
and does not require any service or maintenance, said BVI. “Within a<br />
minute of opening the sterile blister I am ready to treat retinal tears or<br />
detachment, whether I’m in my office or in the operating room,” said<br />
Prof Stanislao.<br />
CryoTreq enables a minimally invasive ab externo approach to<br />
treat retinal tears and detachments, providing an alternative to laser<br />
photocoagulation, especially for lesions located towards the anterior<br />

FEATURE<br />
By Louise Wood<br />
ELECTRONIC CIGARETTES<br />
(E-CIGARETTES) or vaping devices heat<br />
nicotine, flavours and other chemicals to create<br />
a vapour the user inhales. Vaping has been<br />
marketed as a substitute for tobacco cigarettes to<br />
help smokers kick their addiction, but vaping’s<br />
harmful effects are still largely unknown.<br />
Nicotine is addictive¹ and is found in the<br />
majority of e-cigarettes, potentially making<br />
them as addictive as tobacco, leading the US<br />
Food and Drug Administration to classify<br />
them as “tobacco products”. More worryingly,<br />
a 2019 study found 64% of e-cigarette users<br />
in New Zealand were still smoking tobacco²,<br />
compounding health risks.<br />
Vapour vs tobacco?<br />
The health implications of vaping are starting<br />
to emerge in the literature. A paper published<br />
last year in Respiratory Research, revealed<br />
the bacterial persistence and inflammatory<br />
potential in the lungs caused by e-cigarette<br />
vapour is similar to that found in a tobacco<br />
smoker³. Lead researcher Dr Deirdre Gilpin<br />
said, “Bacteria have long been associated with<br />
the development of lung diseases, such as<br />
bronchitis and pneumonia, where smoking<br />
plays a role. Our study is the first of its kind<br />
which aimed to compare the effect of cigarette<br />
smoke and e-cigarette vapour on key lung<br />
bacteria. E-cigarettes are perceived as being<br />
safer and we are really concerned about that.”<br />
Nicotine in tobacco and e-cigarettes is<br />
associated with cardiovascular risks and<br />
activation of carcinogenic pathways, including<br />
proliferation and angiogenesis, and can<br />
predispose a person to inflammation, infection<br />
and neoplastic disease¹ , ⁴. Studies have also<br />
shown second-hand e-cigarette exposure leads<br />
to the same nicotine blood levels as secondhand<br />
cigarette smoke inhalation⁴. Plus, like<br />
tobacco, e-cigarettes contain high levels of<br />
formaldehyde and other carcinogens, such as<br />
acetaldehyde⁴, and a 2015 study showed an<br />
increase in bacterial virulence and decrease in<br />
host defence with e-cigarettes when compared<br />
with tobacco⁵.<br />
Tobacco and the eye<br />
We have long understood how smoking<br />
tobacco can affect the integrity of the ocular<br />
surface and contribute to the development<br />
of macular degeneration and cataracts.<br />
Chronic smoking has also been linked to<br />
squamous metaplasia and loss of goblet cells<br />
which makes it a significant risk factor in the<br />
development of ocular surface disease⁶ , ⁷.<br />
Smoking promotes molecular and<br />
pathological changes in the body: vascular<br />
inflammation, endothelial cell abnormality,<br />
oxidative and toxic damage⁸. These changes can<br />
lead to the development of macular degeneration<br />
and choroidal neovascular membranes. An<br />
increased prevalence of age-related cataracts<br />
has also been associated with smoking⁹. Several<br />
biological mechanisms have been put forward<br />
for the likely cause including oxidative damage,<br />
chemicals causing lens toxicity and opacity and<br />
increased aldehyde levels in smokers’ blood<br />
which modifies lens proteins.<br />
Vaping and the eye<br />
The effect of vaping on ocular health is still<br />
widely unknown but literature is evolving.<br />
Complaints of eye irritation by users and<br />
bystanders when exposed to vaping aerosols<br />
have been reported but there’s been few peerreviewed<br />
studies. Formaldehyde is a biproduct<br />
of combustion in tobacco and e-cigarettes<br />
and the American National Cancer Institute<br />
warned that when airborne, it can cause a<br />
burning sensation and watering of the eyes.<br />
Another known eye irritant, propylene glycol<br />
is also one of the common base ingredients of<br />
vape e-liquid. Exposure to it can cause ocular<br />
and respiratory irritation 10 .<br />
In the first study of its kind, published in<br />
September 2019, Malaysian researchers looked<br />
at ocular surface data from 21 vapour users<br />
and compared it with 21 non-smokers¹¹. They<br />
looked at the clinical features of the ocular<br />
surface, tear breakup time, fluorescein breakup<br />
time, surface staining, tear meniscus and<br />
Schirmer test scores to evaluate ocular surface<br />
health. Results revealed a significant reduction<br />
in non-invasive tear breakup time, fluorescein<br />
breakup time and tear meniscus height when<br />
compared with non-smokers, while an increase<br />
in vaping voltage increased tear film instability,<br />
indicating vapour users experience moderateto-severe<br />
symptomatic dry eye when compared<br />
to healthy non-smokers.<br />
There has been no specific research into<br />
other ocular side effects of e-cigarettes though<br />
a 2014 study found that nicotine can affect the<br />
eye when ingested¹². In this study, patients<br />
who chewed nicotine gum had significantly<br />
thinner choroids than non-gum chewers,<br />
possibly as a result of reduced ocular blood<br />
flow from the vasoconstrictive properties of<br />
nicotine. Thus, given the presence of nicotine<br />
in most e-cigarettes, it is reasonable to assume<br />
comparable side effects. Similarly, an increased<br />
prevalence of age-related cataracts may be<br />
connected to the toxic chemicals found in<br />
e-cigarette vapour in much the same way<br />
studies have found with tobacco use.<br />
In conclusion<br />
Vaping is becoming a popular craze, especially<br />
among younger people. Vaping products have<br />
been found to transiently reduce blood flow<br />
and oxygen use in the body, and the eye has a<br />
great demand for both. It may take decades to<br />
categorically determine if it is a safer longterm<br />
option than tobacco, but e-cigarette use<br />
is rapidly increasing and preliminary research<br />
shows close similarities between the two.<br />
We should continue to counsel patients on<br />
their lifestyle choices and how these may affect<br />
their health with time. E-cigarettes may be<br />
used as an alternative to tobacco to help with<br />
smoking cessation but should be stopped as<br />
soon as possible to mitigate long-term health<br />
issues, including eye disease.<br />

Vaping legalities in NZ<br />
The Ministry of Health (MoH) ruled<br />
the sale of nicotine-containing vaping<br />
devices was legal in New Zealand in May<br />
2018. Following criticism, the Smokefree<br />
Environments and Regulated Products<br />
(Vaping) Amendment Bill was put to<br />
Parliament on 24 February <strong>2020</strong> to:<br />
• Ban the sale of vaping products to under-18-year-olds<br />
• Stop vaping or smokeless tobacco use in smokefree areas<br />
• Prohibit advertising of vaping products<br />
• Restrict the sale of flavoured vaping products and e-cigarettes<br />
to R-18 specialty stores, and limit general retailers’ sales to three<br />
flavours<br />
• Introduce a product safety system, enabling the MoH to recall,<br />
suspend and issue warnings about vaping products<br />
“The Bill aims to strike the right balance between making sure<br />
vaping is available for smokers who want to use it as a quit tool<br />
for cigarettes while ensuring vaping products are not marketed or<br />
sold to children and young people,” said associate health minister<br />

But many are concerned restrictions don’t go far enough,<br />
including some who profit from the industry. “Currently, it appears<br />
that anyone will still be able to make a purchase from an overseas<br />
website and have the product shipped to their door, which may<br />
bypass age restrictions and quality controls,” said Paul Williamson<br />
from Shosha, the country’s largest retailer of e-cigarettes.<br />
The government has set a long-term goal of making New<br />

CXL-assisted infection reduction: a<br />
randomised clinical trial evaluating the<br />
effect of adjuvant CXL on outcomes in<br />
fungal keratitis<br />

Ophthalmology <strong>2020</strong> Feb;127(2):159-166<br />
Design: Randomised control trial of 403 patients<br />
with smear-positive filamentous fungal keratitis.<br />
Eyes were randomised to one of four treatment<br />
arms: (1) topical natamycin 5% alone; (2) topical<br />
natamycin 5% plus cross-linking (CXL); (3) topical<br />
amphotericin B 0.15% alone; or (4) topical<br />
amphotericin B 0.15% plus CXL.<br />
Outcome: There was no difference in culture<br />
positivity 24 hours after commencing treatment<br />
between those randomised to amphotericin or<br />
natamycin, regardless of whether they received<br />
CXL. Those that received CXL had worse visual<br />
acuity (VA) outcomes: best corrected VA was<br />
0.22 logMAR (2.2 Snellen lines) worse at three<br />
weeks and 0.32 logMAR (3.2 Snellen lines) worse<br />
at three months. There was no difference in<br />
infiltrate, scar size or adverse events between<br />
the groups.<br />
New RP therapy<br />
SCIENTISTS HAVE DEVELOPED a new gene<br />
therapy approach that could treat retinitis<br />
pigmentosa (RP).<br />
Genetics, virology and ophthalmology<br />
researchers from Trinity College Dublin and<br />
University College London (UCL) teamed up<br />
to deliver a normal, functioning copy of the<br />
RP2 gene, which provides instructions for<br />
making a protein essential for normal vision,<br />
into ‘mini retinas’, engineered from stem cells<br />
and containing a defective form of the gene.<br />
The mini retinas successfully took up the<br />
functioning RP2 gene and produced the<br />
essential protein resulting in significant<br />
improvement, said PhD researcher Ciara<br />
Shortall, co-author of the study published in<br />
Stem Cell Reports.<br />
“It is an important development that we<br />
can now reproduce so many elements of<br />
inherited disease using these mini retinas.<br />
It makes it possible for us to study in<br />
detail why people go blind and try to find<br />
ways to prevent blindness,” said Professor<br />
Michael Cheetham from UCL which led the<br />
development of the mini retinas to road-test<br />
the gene therapy.<br />
Limitations: This study was performed in<br />
India, where there is a high incidence of fungal<br />
keratitis often associated with agricultural<br />
exposure. The spectrum of organisms<br />
responsible for fungal keratitis in New<br />
Zealand and other developed countries may<br />
be different and exhibit dissimilar response<br />
patterns to treatment. As the study included<br />
eyes with fungal keratitis due to multiple<br />
filamentous organisms, only small numbers<br />
of individual fungi were included making it<br />
difficult to detect the presence of a benefit for<br />
CXL for any particular organism.<br />
Comment: Fungal keratitis remains a<br />
challenging condition to manage. Despite the<br />
recent interest in CXL as a treatment option in<br />
microbial keratitis, this article suggests there<br />
is no benefit in using adjuvant CXL in the<br />
treatment of filamentous fungal keratitis and it<br />
may result in worse visual outcomes.<br />
Efficacy of amniotic membrane<br />
transplantation for the treatment of corneal<br />
ulcers<br />
Schuerch K, Baeriswyl A, Frueh BE, Tappeiner C<br />
Cornea <strong>2020</strong> Apr;39(4):479-483<br />
Design: Retrospective analysis of 149<br />
patients treated with amniotic membrane<br />
transplantation (AMTX) for refractory corneal<br />
ulcers. The underlying cause of the ulcers<br />
were diverse, including herpetic, bacterial and<br />
rheumatic disease, previous corneal surgery,<br />
bullous keratopathy, limbal stem cell deficiency<br />
and neurotrophic ulcers.<br />
Outcome: The mean duration between ulcer<br />
onset and AMTX was 42 ±46 days. However,<br />
it occurred much earlier for cases following<br />
chemical injury (mean 14 days) compared to<br />
bacterial keratitis (mean 65 days). In 70% of<br />
cases, a single AMTX was sufficient to achieve<br />
epithelial closure: 21% within the first month,<br />
40% within one to three months and 9% within<br />
three to six months. Epithelial closure was also<br />
achieved in 41% and 40% respectively of those<br />
undergoing a second and third AMTX. The<br />
highest epithelial closure rates were found in<br />
neurotrophic, herpetic and bacterial ulcers (93%,<br />
85% and 80% respectively). The lowest success<br />
rates were found in ulcers after corneal surgery<br />
or associated with rheumatic disease (52% and<br />
57% respectively).<br />
Limitations: This was a retrospective study<br />
with no control group.<br />
Comment: Amniotic membranes contain a high<br />
concentration of fibroblast growth factors and<br />
cytokines. It forms a mechanical barrier and<br />
promotes epithelial recovery while suppressing<br />
inflammation. It offers a valuable treatment<br />
option to promote corneal epithelial healing<br />
in refractory ulcers particularly neurotrophic,<br />
herpetic and bacterial ulcers. Even if not initially<br />
successful, a second or even third AMTX may<br />
result in epithelial healing.<br />
A case-control study of keratoconus risk<br />
factors<br />
Moran S, Gomez L, Zuber K, Gatinel D.<br />
Cornea <strong>2020</strong> Jun;39(6):697-701<br />
Design: Single centre, prospective case control<br />
study evaluating 202 patients with keratoconus<br />
and 355 controls. Patients were surveyed<br />
regarding their ophthalmic and medical<br />
histories and data regarding multiple variables<br />
was gathered and analysed.<br />
Outcome: After multivariate analysis, the<br />
following factors showed significant results:<br />
eye rubbing with knuckles or fingertips, history<br />
of dry eye, male sex, night-time work, increased<br />
screen time, prone and side sleep position were<br />
all associated with keratoconus. Conversely,<br />
sleeping supine was found to be a protective<br />
factor. No link was found between a family<br />
history of keratoconus and development of the<br />
condition.<br />
Limitations: Most of the data required for this<br />
study was reliant on patients’ history which is<br />
dependent on patient recollection and subject<br />
to recall bias, and there was a relatively small<br />
number of patients included.<br />
Comment: The high prevalence of keratoconus<br />
in New Zealand is well known. Despite great<br />
improvements in diagnosis and management<br />
in recent years, the underlying pathogenesis<br />
is still a subject of debate. Eye rubbing has<br />
long been implicated as an exogenous<br />
environmental factor in the development of<br />
keratoconus, however this study also implicates<br />
other associations including sleep position,<br />
night-time work and screen time. These<br />
associations may merit further investigations<br />
and may guide future advice to patients at risk.<br />

EYLEA ® (aflibercept) EYLEA is used in ophthalmology. Prescription medicine. 40 mg/mL solution for intravitreal injection containing aflibercept. INDICATIONS: EYLEA (aflibercept)<br />
is indicated in adults for the treatment of neovascular (wet) age-related macular degeneration (wet AMD), visual impairment due to macular oedema secondary to central retinal vein<br />
occlusion (CRVO), visual impairment due to macular oedema secondary to branch retinal vein occlusion (BRVO), diabetic macular oedema (DME), visual impairment due to myopic choroidal<br />
neovascularisation (myopic CNV). DOSAGE REGIMEN AND ADMINISTRATION: 2 mg aflibercept (equivalent to injection volume of 50 µL). The interval between doses injected into<br />
the same eye should not be shorter than one month. Once optimal visual acuity is achieved and/or there are no signs of disease activity, treatment may then be continued with a treatand-extend<br />
regimen with gradually increased treatment intervals to maintain stable visual and/or anatomic outcomes. If disease activity persists or recurs, the treatment interval may be<br />
shortened accordingly. Monitoring should be done at injection visits. There is limited information on the optimal dosing interval and monitoring interval especially for long-term (e.g. >12<br />
months) treatment. The monitoring and treatment schedule should be determined by the treating ophthalmologist based on the individual patient’s response. If visual and anatomic outcomes<br />
indicate that the patient is not benefiting from continued treatment, EYLEA should be discontinued. For wet AMD: Based on the physician’s judgement of visual and/or anatomic outcomes,<br />
the treatment interval may be maintained at two months or further extended using a treat-and-extend dosing regimen, by increasing injection intervals in 2- or 4-weekly increments while<br />
maintaining stable visual and/or anatomic outcomes. If visual and/or anatomic outcomes deteriorate, the treatment interval should be shortened to a minimum of four weeks based on<br />
anatomical and/or visual outcomes. Generally, once optimal visual acuity is achieved and/or there are no signs of disease activity, the treatment interval may be adjusted based on visual and/<br />
or anatomic outcomes. Treatment intervals greater than four months (16 weeks) between injections have not been studied. For CRVO: Treatment is initiated with one injection per month for<br />
three consecutive months. After the first three monthly injections, the treatment interval may be adjusted based on visual and/or anatomic outcomes. For BRVO: Treatment is initiated with<br />
one injection per month for three consecutive months. After the first three monthly injections, the treatment interval may be adjusted based on visual and/or anatomic outcomes. For DME:<br />
Treatment is initiated with one injection per month for five consecutive months, followed by one injection every two months. After the first 12 months, the treatment interval may be adjusted<br />
based on visual and/or anatomic outcomes. For myopic CNV: EYLEA treatment is initiated with one injection of 2 mg aflibercept (equivalent to 50 µL). Additional doses should be administered<br />
only if visual and/or anatomic outcomes indicate that the disease persists. Recurrences are treated like a new manifestation of the disease. CONTRAINDICATIONS: Known hypersensitivity<br />
to aflibercept or excipients; ocular or periocular infection; active severe intraocular inflammation. PRECAUTIONS: Endophthalmitis, increase in intraocular pressure; immunogenicity;<br />
arterial thromboembolic events; bilateral treatment; risk factors for retinal pigment epithelial tears; treatment should be withheld in case of rhegmatogenous retinal detachment, stage 3 or 4<br />
macular holes, retinal break, decrease in best-corrected visual acuity of ≥30 letters, subretinal haemorrhage or intraocular surgery; treatment not recommended in patients with irreversible<br />
ischemic visual function loss; population with limited data (diabetic macular oedema due to type 1 diabetes, diabetic patients with HbA1c >12%, proliferative diabetic retinopathy, active<br />
systemic infections, concurrent eye conditions, uncontrolled hypertension, in myopic CNV there is no experience in the treatment of non-Asian patients, previous treatment for myopic CNV<br />
and extrafoveal lesions), see full Data Sheet for effects on fertility, pregnancy, lactation, effects on ability to drive or use machines. INTERACTIONS: No formal drug interaction studies have<br />
been performed. ADVERSE EFFECTS: Very common: conjunctival haemorrhage, visual acuity reduced, eye pain. Common: retinal pigment epithelial tear, detachment of retinal pigment<br />
epithelium, retinal degeneration, vitreous haemorrhage, cataract, cataract cortical, cataract nuclear, cataract subcapsular, corneal erosion, corneal abrasion, intraocular pressure increased,<br />

Understanding<br />
Charles Bonnet Syndrome<br />
By Naomi Meltzer<br />
IMAGINE BEING A passenger in a car and a<br />
brick wall suddenly appears in front of you, or<br />
rows of brown, high-rise buildings start to sway<br />
and bend gracefully towards you. Perhaps, as<br />
you prepare for bed, you pull back your covers<br />
and find a brown, furry thing there. You’re not<br />
afraid because although you have no pets,<br />
you have seen this furry thing quite frequently<br />
recently.<br />
These are real examples of Charles Bonnet<br />
Syndrome (CBS) as told to me by sane, lucid and<br />
sometimes, understandably, extremely anxious<br />
people.<br />
Another patient of mine recalled finding<br />
her retirement village garden planted with<br />
gloriously coloured flowers and even thanked<br />
the gardener before returning to her apartment<br />
to find the flowers had disappeared. While<br />
another said she saw an army of Roman-like<br />
soldiers, marching around the room before<br />
disappearing into the ceiling. Her husband<br />
laughed and called her a “silly old ding-bat”.<br />
Though CBS hallucinations are rarely the<br />
stuff of horror movies, they are confusing and<br />
worrying for patients, leading many to question<br />
their own sanity.<br />
Patient hallucination description, involving Lilliputian visions, which<br />
are commonly seen in patients suffering from CBS³<br />
The syndrome is named after the 18thcentury<br />
Swiss naturalist and philosopher<br />
Charles Bonnet who first described the visual<br />
hallucinations in 1760, after his 87-year-old<br />
grandfather began telling him what he’d been<br />
seeing. Bonnet’s grandfather was thought<br />
to have macular degeneration and possibly<br />
cataracts and, until quite recently, it was<br />
thought that CBS only occurred in conjunction<br />
with macular degeneration. Recent research,<br />
however, indicates it’s associated with a loss of<br />
a patient’s visual ability to distinguish an object<br />
from its background, which can occur with<br />
many visual or neurological conditions.<br />
Mary Lou Jackson, an ophthalmologist and<br />
director of the Vision Rehabilitation Center at<br />
Harvard Medical School, has published several,<br />
frequently quoted papers investigating CBS<br />
in glaucoma patients. Her research indicates<br />
CBS occurs in similar frequency in glaucoma<br />
patients to other eye and neurological<br />
conditions and also concluded its appearance<br />
is most closely linked to contrast sensitivity loss<br />
rather than visual acuity.<br />
In CBS, a person often sees complex visual<br />
hallucinations such as patterns like brickwork,<br />
“Not one, but a whole herd of elephants, blocking the main street of Taupo…”<br />
said Gael Spence, sharing one strange, realistic hallucination 2<br />
basketwork or lace, superimposed on everyday<br />
items like walls or furniture, or people,<br />
animals or inanimate objects, not necessarily<br />
identifiable as something previously seen. The<br />
defining elements which differentiate CBS from<br />
other hallucinatory conditions include:<br />
l Well-formed visual hallucinations the patient<br />
can describe, rather than vague flashes of light<br />
l Insight into the unreal nature of the<br />
hallucination, especially after it is explained to<br />
the patient. For example, a patient told me how<br />
on waking she’d found papers scattered on her<br />
bedroom floor. She knew there was no open<br />
window and no pile of papers that could be<br />
blowing around, yet she still got out of bed to<br />
pick them up before they disappeared<br />
l Some degree of vision loss before<br />
experiencing the hallucinations<br />
l No other previously diagnosed psychiatric<br />
or neurological diagnoses to explain the<br />
hallucination, i.e. the patient appears to have<br />
no other sign of dementia or cognitive change<br />
CBS hallucinations are thought to<br />
originate in the brain. Many attribute them<br />
to deafferentation causing a lack of true<br />
visual input into the<br />
visual cortex, which<br />
results in a release<br />
phenomenon analogous<br />
to phantom pain after<br />
limb amputation. Others<br />
simply describe the<br />
phenomenon as the<br />
brain trying to fill in the<br />
gaps in a patient’s vision,<br />
where, without visual<br />
input, unregulated visual<br />
cortex activity emerges<br />
as hallucinations.<br />
28 | NEW ZEALAND OPTICS JULY <strong>2020</strong>
EDUCATION<br />
The exacerbation of social isolation<br />
Regardless of the origin, it is well documented<br />
that the occurrence of visual hallucinations<br />
increases at times of sensory deprivation,<br />
such as when a person is socially isolated or<br />
in the early hours of the morning when the<br />
sufferer is awake, but there is nothing much<br />
else happening. Usually it disappears when<br />
distractions, such as the radio or television, or<br />
some new activity are initiated.<br />
The prevalence of CBS in elderly patients is<br />
reported to be anywhere from 0.5% to 40%;<br />
the high variance due to CBS frequently being<br />
attributed to mental illness. Generally, however,<br />
it is thought to affect about 30% of patients<br />
with some form of vision loss. But it is believed<br />
to be heavily under reported due to patient<br />
anxiety about the onset of dementia and<br />
negative comments from family, friends and<br />
medical personnel.<br />
My experience, from talking to almost all of<br />
my low vision patients about CBS, is that this<br />
anxiety is warranted. It does not matter how<br />
sensitively I initiate the conversation, a large<br />
proportion of accompanying family and indeed<br />
patients, will immediately make some sort of<br />
joke or negative comment. For those who have<br />
experienced CBS however, I can usually sense a<br />
change in body language immediately.<br />
A simple question such as, “has<br />
anything like that ever happened<br />
to you?” can result in a myriad<br />
of responses from tears of relief<br />
to embarrassment or anger that<br />
nobody took them seriously when<br />
they tried to speak of it.<br />
Although CBS is usually associated Charles Bonnet<br />
with visual hallucinations, it also occurs<br />
with other sensory deprivation. There are<br />
similar phenomena reported for the olfactory<br />
and auditory senses. Olfactory deprivation has<br />
been shown to result in functional changes<br />
and even structural changes, such as decreased<br />
mucosa thickness in the nose and possible<br />
changes in the number of receptor neurons.<br />
In the auditory pathways, tinnitus is defined<br />
as a perception of a sound that is not related<br />
to an acoustic source or electrical stimulation.<br />
Usually, but not always, this is associated<br />
with hearing loss. It can range from simple<br />
sounds to complex musical or even verbal<br />
hallucinations. Was Beethoven experiencing<br />
auditory CBS?<br />
One experience of a 99-year-old widow<br />
continues to resonate with me. Fiercely<br />
independent and very lucid, this lady had<br />
resisted moving out of her home into a rest<br />
home for a long time. Three weeks after she<br />
gave in and moved, and before staff<br />
had really got to know her, she<br />
noticed a man standing by her bed<br />
in the early hours of the morning.<br />
As she watched he floated up into<br />
the top corner of her wardrobe and<br />
disappeared. He appeared several<br />
times over the next few weeks and<br />
unwilling to speak to staff about it for fear<br />
that they would write her off as a dementia case,<br />
she concluded it was the ghost of a previous<br />
occupier and continued to worry he was trying<br />
to tell her something. As she related this to me,<br />
her younger sister who was hearing all this for<br />
the first time was clearly aghast at what must<br />
have been a frightening experience alone in<br />
this new place. She asked her sister, was it her<br />
husband who appeared by her bed leaning<br />
over her? “Oh no” said the 99-year-old with a big<br />
smile, “he was much more handsome.”<br />

Residual refractive error after<br />
cataract surgery<br />
By Drs Ye Li and Mo Ziaei<br />
CATARACT SURGERY IS the most<br />
commonly performed operation globally,<br />
with over 30,000 performed per annum in<br />
New Zealand. The surgery has transformed<br />
into a refractive procedure in recent years,<br />
with patients often expecting the surgery<br />
to minimise their dependence on glasses.<br />
However, residual refractive error following<br />
surgery is still relatively common. In 2015,<br />
postoperative visual and refractive outcomes<br />
in New Zealand were found to be comparable<br />
to international standards¹, which aims to<br />
have 85% of patients achieve a spherical<br />
equivalent (SE) within 1 dioptre (D) and 55%<br />
of patients within 0.5D of the intended target².<br />
This translates into more than 4,500 patients<br />
a year with a residual refractive error of >1D<br />
following surgery every year.<br />
Multidisciplinary care of the cataract patient<br />
is continuously evolving to meet postoperative<br />
refractive benchmarks, with the development<br />
of an assortment of intraocular lenses (IOLs),<br />
advanced biometric measurements, modern<br />
IOL calculation formulae and the improvement<br />
in surgical options available to perform<br />
postoperative enhancement.<br />
Current cataract surgery techniques<br />
Phacoemulsification remains the gold standard<br />
technique for cataract surgery. It has replaced<br />
previously conventional methods such as<br />
intracapsular cataract extraction (ICCE),<br />
extracapsular cataract extraction (ECCE)<br />
and manual small incision cataract surgery<br />
(MSICS), due to advantages in visual outcomes<br />
and a lower complication rate.<br />
Recently, the femtosecond laser has been<br />
employed for use in cataract surgery due<br />
to theoretically higher precision in surgical<br />
incisions, more predictable capsulotomy<br />
and reduced ultrasound energy. There is a<br />
sparsity of large, long-term studies comparing<br />
femtosecond laser-assisted cataract surgery<br />
to phacoemulsification, however, at this<br />
stage, there is no compelling evidence to<br />
suggest significant differences in refractive<br />
or visual outcomes. One European registry<br />
study suggests that femtosecond laserassisted<br />
cataract surgery has a similar<br />
intraoperative complication profile compared<br />
with phacoemulsification but a higher rate of<br />
postoperative refractive surprise due to corneal<br />
oedema and posterior capsule opacification.<br />

Minimising preoperative sources of error<br />
Recognising potential sources of postoperative<br />
refractive error is instrumental in achieving<br />
desirable postoperative outcomes. In most<br />
cases, a detailed ocular history, thorough<br />
examination and appropriate imaging is<br />
adequate for detecting significant risk factors<br />
that converge to lead to inappropriate IOL<br />
power selection. Such risk factors include<br />
ocular surface disease (OSD), contact lens<br />
wear, prior refractive surgery, keratoconus,<br />
astigmatism and extremes of axial length<br />
(AL).<br />
Ocular surface disease<br />
OSD is an underdiagnosed condition that has<br />
a prevalence of 5-50% globally. One study of<br />
patients presenting for cataract assessment<br />
revealed that 77% of cases exhibited corneal<br />
fluorescein staining, while only 22% had a<br />
formal diagnosis of dry eye. Untreated OSD<br />
resulting in hyperosmolarity and tear film<br />
instability, compromises the quality of the<br />
refractive surface, which directly affects<br />
keratometric measurements and can lead to<br />
erroneous measurements of keratometric<br />
astigmatism. Errors in measured astigmatism<br />
can be significant in IOL power calculations,<br />
particularly for astigmatic correcting (toric)<br />
IOLs.<br />
Error due to OSD can be avoided<br />
through vigilant assessment and subsequent<br />
comprehensive treatment of the ocular surface<br />
for at least four weeks, at which point repeat<br />
biometry measurements will be necessary.<br />
Treatment should involve frequent lubrication<br />
and lid hygiene with adjuvant treatment<br />
such as topical steroid and oral azithromycin<br />
reserved for recalcitrant cases.<br />
Contact lens wear<br />
Contact lens wearers are also subject to an<br />
increased risk of postoperative refractive<br />
error. Extensive contact lens wear leading<br />
to prolonged hypoxia and subsequent<br />
corneal warpage can influence the<br />
accuracy of keratometric measurements³.<br />
Discontinuation of contact lens wear for<br />
a minimum of two to three days for soft<br />
lens and one to two weeks for rigid gas<br />
permeable lenses, prior to biometric and<br />
topographic measurements, is essential. A<br />
more prolonged discontinuation period may<br />
be required if the preoperative biometric<br />
and topographic measurements still exhibit<br />
evidence of corneal warpage, and multiple<br />
visits and measurements may be required in a<br />
small proportion of patients.<br />
Refractive surgery<br />
Prior refractive surgery, such as laser in<br />
situ keratomileusis (LASIK), laser epithelial<br />
keratomileusis (LASEK), photorefractive<br />
keratectomy (PRK) and radial keratotomy<br />
(RK), can instigate multiple errors in<br />
IOL power calculations due to erroneous<br />
preoperative keratometric measurements⁴.<br />
Traditional topography and biometry<br />
devices only measured the anterior radius<br />
of curvature while assumptions were made<br />
about the posterior cornea contribution<br />
for the index of refraction. After all types<br />
of refractive surgery, with the exception of<br />
RK where anterior-posterior changes are<br />
relatively proportional, these assumptions<br />
are violated. If not accounted for, patients<br />
with myopic refractive surgery generally<br />
experience a hyperopic shift following<br />
cataract surgery and a myopic surprise<br />
can be expected after hyperopic refractive<br />
surgery. Development of multiple modern<br />
IOL formulae and supplementary adjustment<br />
tools have tailored calculations to account for<br />
these factors, but it remains prudent upon<br />
the referring optometrist and the cataract<br />
surgeon to actively ask for a history of<br />
refractive surgery.<br />

FOR ALL EYE CARE PROFESSIONALS<br />

Keratoconus<br />
Other conditions resulting in corneal<br />
irregularities, such as corneal ectasia, present<br />
similar challenges in IOL calculations. Accurate<br />
biometry measurements are notably difficult to<br />
obtain in patients with keratoconus, especially<br />
in those with severe disease who are more<br />
prone to cataract formation due to concurrent<br />
atopy and possible previous topical steroid<br />
use. Displacement of the steep axis causing<br />
misalignment with the visual axis and the<br />
presence of severe corneal distortion induces<br />
error in keratometric measurements and<br />
effective lens position, typically resulting in an<br />
underestimated IOL power and postoperative<br />
hyperopia. In preoperative assessments, vigilant<br />
detection for keratoconus, accurate staging and<br />
obtaining an understanding of the patient’s<br />
disease status and possible progression can be<br />
essential in minimising postoperative refractive<br />
error which may have accentuated downstream<br />
effects due to future interventions that may be<br />
required for the treatment of the ectatic process<br />
(eg. keratoplasty).<br />
Astigmatism<br />
Astigmatism can be challenging to address<br />
and accurate assessment of its magnitude<br />
is helpful in surgical planning. Previous<br />
research has revealed the residual refractive<br />
error is more common in individuals with<br />
higher levels of preoperative astigmatism.<br />
Varying degrees of astigmatism are managed<br />
differently. Patients with 1D often benefit from<br />
a toric IOL⁵. A recent meta-analysis showed<br />
that toric IOLs are superior in astigmatism<br />
correction compared to corneal incisions, but<br />
these lenses need to be placed accurately on<br />
the steep axis in order to effectively neutralise<br />
astigmatism⁶.<br />
Axial length and modern formulae<br />
Patients with extremes of AL are also more<br />
prone to refractive surprise. The use of<br />
modern biometry devices that use optical<br />
coherence tomography (OCT) to generate<br />
Fig 3. LASIK enhancement in a patient with hyperopic<br />
refractive surprise following routine cataract surgery<br />
accurate AL measurements as well as modern<br />
formulae has led to a significant reduction<br />
in refractive error. The recently introduced<br />
formulae analyse multiple biometric<br />
parameters such as AL, keratometry, lens<br />
thickness, anterior chamber depth and whiteto-white<br />
distance, and employ regression<br />
models or artificial intelligence to better<br />
predict the postoperative position of the IOL<br />
(effective lens position) and improve refractive<br />
outcomes. In one recent study, the refractive<br />
accuracy was found to be most challenging to<br />
achieve in short eyes

Business post-Covid-19: our new normal<br />
By David Pearson<br />
THE COVID-19 PANDEMIC will likely change<br />
the way we do business for a long time<br />
to come. For most businesses’ turnover is<br />
down and owners are having to deal with<br />
an environment that is constantly changing,<br />
affecting inventory requirements (especially<br />
those reliant on imports) and staffing capacity.<br />
Maintaining profitability or, in some cases<br />
viability and liquidity, can prove challenging.<br />
Here are some key elements to increase the<br />
likelihood of success.<br />
Short-term cash flow forecast<br />
Prepare a 13-week cash flow forecast. This<br />
is often an eye-opening exercise and will<br />
effectively capture most entities’ business cycles.<br />
The forecast will help navigate stormy waters<br />
in the near-term, as it will highlight shortfalls<br />
in necessary cash balances. Maintaining an<br />
up-to-date forecast will allow you to easily<br />
identify if and when there is an upcoming risk of<br />
running out of cash and will reveal if borrowing<br />
requirements fall short of actual availability from<br />
credit lines. You will need to ensure any forecast<br />
is subject to regular revisions in light of Covid-19<br />
and its ongoing impact on the market.<br />
Being in a position to identify when cash<br />
may be short puts you on the front foot to<br />
source more capital or organise new payment<br />
arrangements for extended loan facilities, tax<br />
payment plans, starting conversations about<br />
supplier arrangements and/or liaising with<br />
landlords regarding rent relief.<br />
Monitor actual against forecast<br />
Cash is king! A business can be reporting<br />
profits but still have trouble meeting current<br />
obligations to lenders and key creditors. Having<br />
accurate, monthly financial statements can<br />
prove invaluable in keeping on top of where<br />
your cash flow is at in real time. This also helps<br />
you to fully utilise short-term cash flow to its<br />
full capacity, allowing you to identify problems<br />
that may develop as patients become slower<br />
to pay or don’t pay at all. Some problems<br />
may also not be immediately recognised,<br />
including changes in product/service demands,<br />
increasing overhead costs, use of obsolete<br />
pricing methods or increasing competition due<br />
to industry adaptation.<br />
Where possible review all non-essential<br />
expenses and capital projects to identify<br />
opportunities to free up cash surpluses quickly<br />
if needed. Reviewing inventory levels cannot<br />
be underestimated as post-Covid optimums<br />
may be quite different to pre-Covid optimums<br />
and these changes may also free up working<br />
capital. Finally, ensure your patients clearly<br />
understand your payment terms which must<br />
be targeted at minimising credit terms.<br />
Learning by doing<br />
When faced with great uncertainty, we<br />
have three options: remove the uncertainty<br />
and proceed; proceed anyway and adjust<br />
as necessary; or do nothing. If we assume<br />
option one is unrealistic and option three is<br />
unacceptable, we’re left with only one option<br />
– take action, learn and adapt. The objective<br />
of adaptive management is to provide a<br />
framework that drives action now, despite<br />
uncertainty. The goal is not necessarily a<br />
predetermined target, at least not initially, it’s<br />
about achieving incremental change: take<br />
a small step, reflect, learn, adjust and take<br />
another small step.<br />
Adaptation goes past simply responding to<br />
disruptive events; it also means seeking out<br />
and seizing opportunities created by market<br />
forces. At times like this, it’s this sort of iterative<br />
decision making that should be the foundation<br />
of your strategic planning.<br />
Short-term action plan<br />
The potential output of a short-term action<br />
plan should be a succinct, fit-for-purpose plan<br />
that prioritises the what, who and when for<br />
your business, and can be used as a roadmap<br />
in upcoming months as well as a discussion<br />
document for sharing with stakeholders. The<br />
following areas should be noted:<br />
l Current government rules and requirements<br />
for your business<br />
l What you know for certain, what you can be<br />
doing now to prepare<br />
l Short-term goals<br />
l SWOT analysis<br />
l Overall solvency<br />
l Working capital needs<br />
l Supply chain continuity, logistics<br />
l Patients and sales<br />
l Employment issues and business structure<br />
l Finance and funding (cashflows, plans etc.)<br />
Ideally, a short-term action plan should focus<br />
on a 90-day time period that lends itself to<br />
becoming the basis for a reviewed annual plan.<br />
It’s important you not only focus on the threats<br />
and weaknesses of the current market, but<br />
also identify opportunities to reinvent, grow or<br />
diversify your business offerings and operating<br />
style. While you may not be in the right place<br />
financially to take advantage of these now, they<br />
could possibly be worked into your long-term,<br />
more growth-orientated action plan.<br />
While the above tools will help ensure<br />
your business is well placed to adapt to this<br />
uncertain operating landscape, it’s paramount<br />
the planning put in place is robust and brutally<br />
honest. There is no room for rose-coloured<br />
glasses here! Remember, your business is there<br />
to serve you, not for you to serve it; being<br />
aware of what you need to get out of the<br />
business will provide direction and guidance<br />
for forward momentum.<br />

Continued from p31<br />
When counselling patients regarding<br />
postoperative residual refractive error,<br />
it is important to acknowledge the<br />
patient’s concern and ensure preoperative<br />
measurements are reviewed to confirm the<br />
correct IOL was implanted. After ensuring<br />
the correct IOL was implanted, it is also<br />
important to reiterate that residual refractive<br />
error is not an uncommon issue. Patient<br />
reassurance regarding the availability of<br />
solutions can eliminate potential distress<br />
and dissatisfaction, but before committing<br />
to an enhancement procedure, it is vital to<br />
ensure the patient understands the visual<br />
consequences, particularly if they are left<br />
myopic after surgery and are enjoying the<br />
benefits of unintended “monovision”.<br />
Conclusion<br />
Advances in cataract surgery have enabled<br />
patients to achieve improved visual<br />
outcomes, with the rise of more IOL options,<br />
surgical accessories and improved precision<br />
in IOL power calculation . Despite such<br />
developments, postoperative refractive error<br />
remains relatively common.<br />
Refractive error after cataract surgery<br />
can be minimised through recognition<br />
and correction of potential risk factors. In<br />
instances where the amount of refractive<br />
error is perceived as unacceptable,<br />
enhancement procedures can provide<br />
excellent refractive and visual outcomes.<br />
Whilst perfection in postoperative<br />
refraction cannot yet be guaranteed,<br />
achieving patient satisfaction is absolutely<br />
within reach through patient-centred care,<br />
appropriate counselling and adequate<br />
utilisation of enhancement procedures<br />
following cataract surgery.<br />

Vision monitor app<br />
UK-BASED OKKO Health has launched a new<br />
app allowing eye care practitioners (ECPs) to<br />
monitor their patients’ eyes remotely.<br />
Developed by vision scientists, optometrists<br />
and ophthalmologists, the app instructs<br />
patients to tap on visual cues and pattern<br />
anomalies to assess their visual acuity and<br />
contrast sensitivity. It uses a secure online<br />
portal for ECPs to access readings and identify<br />
patients needing help.<br />
Founder Dr Stephanie Campbell said she<br />
is optimistic about the positive impact the<br />
software will have on vulnerable patients. “With<br />
our app, they can now track key indicators of<br />
De Rigo’s early Christmas<br />
their eye health from the safety of their own<br />
homes. I have no doubt this technology will be<br />
a sight-saver for many.”<br />
DE RIGO HAS launched a Christmas promotion to help independents tempt customers back into<br />
practices while creating a bit of fun and reward participating staff.<br />
“Covid-19 has been very challenging for everyone, however<br />
New Zealand has led the world with its recovery,” said De<br />
Rigo’s Chris Hanley. “De Rigo NZ is running a Christmas<br />
promotion to help continue that recovery by giving practice<br />
staff an added incentive to gain extra Christmas gifts.”<br />
The promotion is running for the next six months and the<br />
rewards catalogue is full of local brands and products which<br />
will also support local businesses, he said.<br />
To be eligible, a practice must stock four De Rigo brands<br />
with a minimum of 12 pieces in each brand. The campaign<br />
runs from 1 June to 30 November <strong>2020</strong>.<br />

When marketing and a crisis don’t mix!<br />
By Siu-Yin Shing<br />
BEFORE EYEWEAR, I worked in PR and marketing for the fashion<br />
sector, so I understand how essential it is for businesses to broadcast<br />
the right messages in today’s social media world because, if you get it<br />
wrong, people are quick to voice their opinion. So, I was curious, when<br />
I saw how many people were angry at cut-price, online frame and lens<br />
company Polette Eyewear. “Ooooo, what did they do to upset their<br />
followers?” I thought.<br />
It wasn’t hard to spot the issue.<br />
Right now, we are in the worst pandemic of<br />
our lifetime. Covid-19 is on the news every day.<br />
Different countries are tackling it (or not) in all<br />
sorts of different ways but wherever you are,<br />
there is no way of not knowing about it.<br />
In the UK, the news regularly reported there<br />
were not enough protective medical supplies for<br />
healthcare workers as cases continued to rise.<br />
It became a top priority to source and deliver<br />
enough masks and sanitisers and other personal<br />
protective equipment (PPE) for health staff on<br />
the frontline, fighting the virus to keep their<br />
patients alive.<br />
Riding the back of this, at the beginning<br />
of the outbreak in Europe in March, Polette<br />
thought it was a good idea to run a See clear,<br />
stay safe promotion giving away two free face<br />
masks with every purchase. The response was<br />
immediate and angry, upsetting about 95% of<br />
the company’s followers on social media.<br />
People felt they were at best insensitive to<br />
the pandemic; at worst, helping to fuel it. Many<br />
asked, “Why give masks to ordinary people like<br />
us when medical staff don’t even have enough<br />
and they are the ones battling Covid-19,” and,<br />
“Why not donate what you have to them?” Both<br />
very valid questions!<br />
Polette’s ill-considered pandemic promotion<br />
Was Polette insensitive?<br />
After SARS in 2002, almost everyone across Asia adopted the habit of<br />
wearing a mask for minor things like a common cold. Wearing a mask<br />
is normal practice; it’s no big deal. But this is not the case in all cultures.<br />
Polette has factories in China and when the outbreak first happened,<br />
masks were hard to find, so many businesses in Hong Kong, for example,<br />
gave out free masks to the general public as a marketing tool.<br />
So I don’t think Polette purposely meant to be<br />
insensitive, but their marketing team should have<br />
done more research and a lot more thinking and<br />
discussing before they jumped into grab some<br />
publicity off the back of the pandemic.<br />
Fuelling the furore<br />
The public reaction was so negative, Polette<br />
made two separate statements explaining its<br />
reasons for the campaign.<br />
The first apologised for any<br />
‘miscommunication’ then rattled on about caring<br />
for its staff in China and the self-proclaimed<br />
good work the company was doing to provide<br />
masks to all, and that the company had values<br />
and heart, “…maybe you considered it misplaced<br />
tonight but if you follow us, you should by now<br />
know where our hearts stand! We thank you for<br />
your support and sorry for hurting all of your<br />
feelings! Polette loves you.”<br />
Instead of quelling the rage, the statement<br />
fuelled it with many lambasting the way they<br />
thought the company had responded with an ad<br />
rather than any words of contrition.<br />
Statement number two was written by the<br />
boss, “Hello everyone, I am Pierre Wizman, I am<br />
French and the founder of polette.com. Our last<br />
communication was not an advertisement but<br />
an act of support in this crisis! I regret that our<br />
34 | NEW ZEALAND OPTICS JULY <strong>2020</strong>
STYLE NEWS<br />
message was wrongly interpreted, and I<br />
hope you will understand our intention<br />
was never about business but to share<br />
information...”<br />
Again, the statement was long. Again,<br />
Wizman attempted to explain why the<br />
company had run the promotion, “…It is<br />
purely an act of kindness from a country<br />
that is slowly getting out of the crisis.”<br />
But instead of apologising, he claimed<br />
the negative response was not deserved,<br />
“Polette is a brand that always puts a stress<br />
on solidarity and benevolence. All our<br />
actions express more than this message<br />
itself!” He continuing with how good<br />
the company has been and called on its<br />
followers “…to remain united… Polette is a strong and loving family and<br />
will continue to be! Love Pierre Wizman.”<br />
He might have ended the statement with ‘love’, but again all it did<br />
was compound the situation. The company was labelled “arrogant” for<br />
blaming its audience for not understanding what the company was<br />
trying to achieve and stating it was simply trying to do everyone a favour.<br />
This is a non-apology. The company said it was sorry, but then went on<br />
to say that it hadn’t actually done anything wrong and it wasn’t its fault<br />
it had been misunderstood. It even said its followers understood that –<br />
after it had deleted most of the really bad comments, leaving behind just<br />
the not-so negative ones in an attempt to rewrite social media history.<br />
My advice to Polette’s marketing team is to do a lot more research<br />
about different cultures before they launch their next promotional<br />
campaign and, if they muck up again, don’t issue a statement trying to<br />
justify what they did otherwise they will lose yet more of their current<br />
and future customers. Sometimes there is simply no way to rectify a<br />
marketing disaster, except to say, “Sorry. We messed up and we will learn<br />
from it. We can now see why this may be insensitive. Please forgive us.”<br />
How this relates to you<br />
Polette is a big company, so perhaps you’re thinking, what can an<br />
independent practice learn from this? The key for any business of any<br />
size when it comes to your marketing ideas is to know and understand<br />
your audience. If the area you practise in is family orientated for example,<br />
make sure you run events and promotions aimed at families, with plenty<br />
of eyewear suitable for the entire family. Be thoughtful about which topics<br />
might upset your audience, but also think about what might grab their<br />
attention. For families, children’s health is always at the heart of their<br />
parents’ interest and actions, so a good campaign idea might focus on<br />
simple tips to help protect their children’s eyes and eye health, for example.<br />
Many independent practice owners are often a little afraid to use social<br />
media to promote their businesses. Some may even choose not to have<br />
a social media presence to avoid the possibilities of backlash and dealing<br />
with angry or unreasonable customers. But don’t be afraid to reach out to<br />
customers and potential customers through social media and, if you do<br />
get it wrong, to apologise and show empathy. Consumers would much<br />
rather deal with a business that can demonstrate these traits and, if you<br />
handle the situation well, you can actually turn a negative situation into a<br />
positive one.*<br />
So, in summary, here’s a couple of ideas for building awareness for your<br />
business online:<br />
l Understand your local area – is it family, older people or business<br />
orientated, for example? And what sort of things do your audience enjoy/<br />
find interesting/important? Target social media interaction appropriately<br />
l Follow local groups to keep up to date with what’s happening and gain<br />
an even greater understanding of and involvement in your local area,<br />
offering your help and expertise when appropriate to reach more groups<br />
within your area<br />
l Consider timely promotions and information for your audiences. In the<br />
summer say, run a special sunglasses promotion; during winter, when<br />
people are more indoors, on their devices,<br />
discuss blue-light lenses for example<br />
Everyone wants to see instant results<br />
with marketing, but successful marketing<br />
is based on creating a lasting impression<br />
of your business among your target<br />
audience. All marketing should be viewed<br />
as a long-term investment, building<br />
subsequent promotions to gain a lasting,<br />
positive reputation. There is no point in<br />
having a great looking practice, top quality<br />
optometrists and dispensers, offering<br />
great products if you don’t tell people<br />
about it. But, most importantly, do your<br />
research to really understand your practice’s<br />
demographics, so whatever you do say,<br />
makes a good impression on those you’re wishing to reach and, if you do<br />
get it wrong, apologise!<br />

Decades of California style<br />
American surf brand O’Neill was founded in 1952 by Jack O’Neill in San<br />
Francisco and, nearly 70 years later, still embodies its original laidback,<br />
California style. O’Neill’s new optical range includes Kellsy, a glossy, crystal<br />
layered 100% plant-based and biodegradable acetate frame, available<br />
in bright teal, brown, black or purple. Kellsy’s stainless steel moulded<br />
temples and adjustable core-wire tips ensures a comfortable fit. Model<br />
Aidan offers a sheet stainless<br />
steel front and bespoke O’Neill<br />
acetate printed temples,<br />
available in four different colour<br />
combinations. O’Neill also offers<br />
a smaller fit for younger surfers.<br />

Bradley Walsh, the<br />
Dr Who and Coronation<br />
Street actor, footballer and<br />
witty presenter of UK ITV’s The<br />
Chase, now starring in Bradley<br />
Walsh & Son: Breaking Dad on<br />
TVNZ, suffers from blepharitis.<br />
It was during a Chase episode that<br />
viewers flocked to Twitter remarking<br />
on Walsh’s odd behaviour when<br />
he decided to speak out about<br />
his condition. Walsh developed<br />
blepharitis in his teens and told<br />
This Morning hosts that viewers<br />
often mistake him for being<br />
drunk because of his condition. “People don’t realise I have seriously<br />
bad blepharitis. I have to take one pill a day (anti-allergy medication)<br />
for it or I really struggle.” Walsh said he is pondering surgery as a<br />
solution to his problem. “I am going to need my eyes operated<br />
on at some point to sort it out. So many times, people have<br />
commented on how I look. But they don’t realise<br />
that if I take medication, I’m fine,” he said.<br />

Chalkeyes presents...<br />
Read all about it<br />
By David Slack<br />
IF YOU ARE reading this in its lustrous<br />
glossy printed form, you have in your hands<br />
a suddenly quite rare and precious thing: a<br />
magazine.<br />
Things are in turmoil in all kinds of ways<br />
and the media is not missing out on its share.<br />
That party was well underway before this<br />
pandemic.<br />
The worse it gets, the more it seems to<br />
echo farming in 1984: there was clearly a place<br />
for it; there was also clearly no way things<br />
could go on the way they were. Things were<br />
proceeding on the fond assumption the glory<br />
days of export dollars for slabs of frozen meat<br />
and bales of wool would return and all we had<br />
to do was wait and dish out subsidies. It was a<br />
delusion.<br />
Media has had a long, golden age, awash<br />
in advertising dollars. Now those dollars are<br />
being hoovered up by Facebook, Google and<br />
YouTube. Good luck ever getting them back.<br />
Moreover, in a world of free online media,<br />
how do you get people to pay?<br />
For farming, the moment of truth arrived<br />
in 1984 with Rogernomics. In came the free<br />
market, out went the subsidies; no more<br />
oxygen for the patient. For several years, it<br />
was awful carnage. Eventually farming found<br />
a new level; off it went again. Before long, the<br />
accepted wisdom was it had all been inevitable<br />
and the sector was the better for it.<br />
What will become the accepted wisdom<br />
for the media? Probably the prevailing order<br />
was no longer the right size or shape, that<br />
a sustainable future lies beyond the present<br />
arrangement of huge media organisations and<br />
expensive executives.<br />
What are the prospects for those of us who<br />
toil in this particular field, making lustrous<br />
publications, and what are the prospects for<br />
you, the reader, who might like to turn their<br />
lustrous pages?<br />
It doesn’t take all that much to tell a story.<br />
You need someone to begin with, “once upon a<br />
time”, and you need an audience that wants to<br />
hear what happened after that. That’s what the<br />
media is at its heart, perhaps with a preference<br />
sometimes for the story that involves<br />
something that someone, somewhere doesn’t<br />
want anyone to hear.<br />
In this digital world, it’s become possible<br />
to do that without much costly overhead. So,<br />
how about in place of the costly giants, we get<br />
an abundance of smaller operations, offering<br />
many different perspectives to many different,<br />
smaller audiences – crucially – connecting<br />
people sharing a common interest? They<br />
might live in the same neighbourhood, they<br />
might have a love for the same subject, they<br />
may follow a particular field, let’s say, oh,<br />
optometry and ophthalmology.<br />
The important thing is that whatever you<br />
do, whatever your interest, the media can<br />
enrich it, improve it, if it does its job well. The<br />
effect can be remarkable.<br />
For many years now I have had an<br />
association with a newspaper man in Mexico.<br />
His family had a small daily paper, a modest<br />
affair. He went off to study journalism in<br />
America, came home with a head full of ideas<br />
about freedom of the press in a country where<br />
there was none. This was 40 years ago. Back<br />
then, what got printed was determined by how<br />
much someone paid, or how much you were<br />
being threatened. He set about making a whole<br />
new kind of newspaper, one that printed the<br />
truth without fear or favour; no kickbacks, no<br />
censorship. They put it in the paper and put it<br />
on the streets. Every vested interest hated it.<br />
The people loved it.<br />
In the face of fierce and unending resistance<br />
and intimidation, he and his young idealistic<br />
team kept their nerve. They kept on reporting<br />
Credit: pxhere.com<br />
without fear or favour and each day more<br />
people bought a copy, and day by day, year<br />
upon year, that little newspaper grew. Today<br />
they print some of the country’s biggest daily<br />
newspapers and their influence, through<br />
exposing corruption, has been profound. They<br />
continue to succeed because their readers know<br />
they will be able to read in those newspapers<br />
what they cannot find anywhere else.<br />
In an age where you can read for free about<br />
Kardashians and trash, the publication that<br />
reports what no one else is reporting is the one<br />
you turn to. When the online world seems to<br />
be subverting democracy, publications that<br />
speak to our interests and values, that cares<br />
about our community of interest, about you,<br />
are something to prize.<br />
When the dust settles, I hope those will be<br />
the hearts still beating.<br />
