IOL Exchange for Refractive Surprises
Kohnen Thomas
1. Department of Ophthalmology, Goethe University
Especially in very long and short eyes, the targeted refraction after cataract
surgery cannot always be achieved. In these cases the surgeon can
choose between different options to increase the patients› visual outcome.
Options include corneal refractive surgery, the implantation of pseudophakic
supplementary intraocular lenses and the exchange of the implanted
intraocular lens. The lecture summarizes indications for this exchange and
explains surgical procedures including their risks and complications.

Is British Drivers License Rule for Central Scotoma Too Strict for
Japanese Glaucoma Patients Who Are Actually Driving?

1. Kofu Kyoritsu Hospital
Purpose: To know if the British driver›s license rules are too strict for the
Japanese. It is unacceptable if there are 4 continuous scotomata within 20
degrees from fixation by binocular Esterman. To know the relation between
binocular Esterman Score (BES) and Functional Field Score (FFS) for the
early glaucoma and NEI VFQ25 and Eli Peli›s driver›s questionnaires (EPDQ).
Method: 61 glaucoma patients (female 14, male 47, average age 67}11 year
old) with Japanese driver›s license, Esterman binocular program by Humphrey
perimeter and Goldmann III4/e test were performed. BES and FFS were
obtained. VFQ25 and EPDQ for low vision drivers were collected.
Result: 6 patients failed the British rule. BES was 86}16, FFS 92}9.6. The
others (55 patients) passed and BES was 94}9.6 and FFS 93±14. There
were no significant differences. To EPDQ, the failed scored 0.3}0.6 and the
passed 2.3}3.3. The passed scored higher, feeling dangerous about driving.
The correlation against VFQ25 was better in BES rather than FFS in early
glaucoma.
Conclusion: The British rule seems too strict for the Japanese. For early
glaucoma cases there was a better correlation for ES than FFS against VFQ25.

and Referral)
Purpose: Analyze outcome of early intervention by AGV in post-contusion
glaucoma. Inclusion criteria: persistent IOP ?35mmHg for 3weeks or nonresolving
total hyphema.
Methods: 21 adults presenting between Mar 2008-Mar 2011 with contusion
injury. Average age: 34.5yrs. No other co-morbidity. 12 had raised IOP at
presentation and 9 developed ocular hypertension within 1 week of the injury.
The mean peak IOP was poorly controlled with maximal medication. Clinical
features: 15 had hyphema, 7 mydriasis, 16 had angle recession, 2 irido-dialysis
and 6 had retinal ischemia. Exclusion criteria: pre-existing glaucoma, uveitis or
long-term steroids. Surgical intervention: Mean intervention was 28th day posttrauma.
Ahmed glaucoma valve (model FP7) was implanted.
Results: Mean IOP 1st post-op was 13mmHg. Cases were reviewed over 1
year. Mean onset of hypertensive phase was 42 days post-surgery followed by
stabilization phase (mean 26 weeks). At 1 year, 19 eyes achieved IOP control
with/without drug (7 without drug). Mean IOP difference: 18.6 (pre and postoperative).
Analysis by Kaplan-Meier method.
Conclusion: Acute sustained IOP rise leads to trabecular injury and high risk of
nerve damage. This study points to a favorable outcome of cases undergoing
early intervention and controlled decompression with AGV implantation.

The Effect of Ahmed Glaucoma Valve Implantation Wrapped with
Human Amniotie Membrane in the Treatment of Refractory Glaucoma

Purpose: To investigate the clinical outcomes and Security of Ahmed glaucoma
valve implantation (AGV) Wrapped with homemade placenta amniotic
membrane in the treatment of refractory glaucoma.
Methods: 40 patients (42 eyes) suffered from refractory glaucoma were
randomly divided into two groups: AGV was in group B, homemade placenta
amniotic membrane was applied in group A. Intraocular pressure (IOP),the
forms of the filtering blebs and the post-operative complications were analyzed
retrospectively for 1-12 months after Surgery.
Results: The IOP in the group B was significantly higher than that in the group
A (F=3.201, p±3 was
demonstrated in 23 eyes (23.7%) of POAG and 23 eyes (37%) of PACG, who
were on medical management. Correlation of IOP change between right and
left eyes was significant in both POAG and PACD groups.
Conclusion: Undilated IOP on baseline and follow-up are the standards for
target IOP estimation. PACD eyes have significant IOP change after dilatation
compared to POAG eyes.

Continuous IOP Monitoring in Glaucoma Patients Treated with
Tafluprost

1. University of Geneva
Objective: To investigate the ability of the Triggerfish® (Sensimed Inc) sensor
to continuously monitor intraocular (IOP) fluctuations throughout twenty four
hours, and to assess the effect of tafluprost (Saflutan®, Santen Inc) on twenty
four hour IOP profile.
Methods: Twenty patients of glaucoma treated with once-daily tafluprost drops
underwent twenty four hour monitoring with the sensor. Recordings obtained
were evaluated for fluctuations.
