Sequential versus Concurrent KERARINGS Insertion and Corneal
Collagen Crosslinking for Keratoconus
El-Raggal Tamer (1)

Purpose: To evaluate the safety and efficacy of combined KERARINGS
insertion and CXL performed in 1 or 2 sessions and to present the refractive
outcomes.
Methods: This prospective comparative study included 16 eyes of 10 patients
with progressive mild to moderate keratoconus that were divided into two
groups. Group 1 included 9 eyes that underwent KERARINGS insertion
followed by CXL 6 months later; group 2 included 7 eyes that underwent the 2
procedures at the same day. In both groups channel creation was performed
using the Intralase FS 60.
Results: There was statistically significant improvement in both groups’ UDVA
and CDVA, with significant reduction in refractive error and keratometric values
(p0.05). However,
group 2 revealed more statistically significant reduction of keratometric values
on topographical examination (p¼0.046). The stromal haze that developed in
both groups was more marked and persistent in group 2 than in group 1.
Conclusion: Combined KERARINGS insertion and CXL can be performed
safely in 1 or 2 sessions. However, the same-session procedure appears to be
more effective regarding the improvement in the corneal shape.

Purpose: To describe various endothelial migration healing patterns after
Descemet membrane endothelial keratoplasty (DMEK), to determine
the contribution of the donor and host endothelium in the clearance of a
transplanted cornea.
Methods: In a total of 150 consecutive eyes that underwent DMEK for Fuchs
endothelial dystrophy, re-endothelialization patterns were studied. Of these
eyes, 36 showed a ‘stromal gap’ between the ‘descemetorhexis-edge’ and the
graft, or (partial) graft detachment.
Results: Complete corneal clearance was seen in 28/36 (78%) eyes with a
stromal gap, or (partial) detachment, progressing from the periphery toward
the center; and 27/34 (79%) of eyes with normal visual potential reached a
visual acuity of ?20/40 (?0.5) or better. In three eyes that had the Descemet
graft implanted upside-down, a ‘reversed corneal clearance pattern‘ was
observed, i.e. persistent edema where the graft was attached, while the area
overlying the detachment cleared.
Conclusion: Complete graft attachment may not be required for recovery of
corneal clarity after DMEK, but the presence of donor endothelium in the
recipient anterior chamber may be a prerequisite.

Final Visual Outcome?

Purpose: To provide evidence-based care to patients with traumatic cataract.
Methods: This was a prospective cohort study among all patients presenting at
our hospital with traumatic cataracts between January 2003 and December
2009. All information regarding demographic and ocular trauma was collected
on a pre-tested World Eye Trauma Registry form for both the first visit and
follow-up. In particular, we collected specific information about the morphology
of traumatic cataracts; surgical technique was determined accordingly. Data
were entered and analyzed with regard to the relationship between type of
trauma and resulting injury, results achieved with particular surgical techniques,
and the relationship between morphology and final visual outcome. Outcome
measures: Final visual outcome.
Results: Traumatic cataracts of different morphologies showed significant
differences in final visual outcome (?2 test, P = 0.014).
Conclusion: The morphology of traumatic cataract plays an important role in
determining both the appropriate surgical technique and final visual outcome.

Aim: To review the incidence of orbital diseases in South India and to compare
with other case series published.
Methods: Retrospective review of 6328 consecutive patients with orbital
disease.
Results: Of the 6328 patients, 2161 (34.1%) had inflammatory orbital disease,
1965 (31.0%) had systemic conditions involving the orbit, 1277 (20.1%) had
neoplasm, 600 (9.4%) had congenital lesions, 308 (4.8%) had trauma, and 17
(0.2%) had vascular disease.
Conclusions: The most common causes of orbital disease in South India are
inflammatory (34.1%) and systemic conditions (31.0%). With the exception of
higher incidence of inflammatory etiologies, these data are largely consistent
with prior published reports.

The Two Extremes of Visual Outcome of Paediatric Ocular Trauma:
Case Reports
Abdelsabour Abdelazeem Ashraf
1. Faculty of Medicine, Zagazig University
Objective: To report two rare and very interesting cases of ocular trauma in
children showing the two extremes of visual outcome.
Methods: Two case reports of ocular trauma in children are presented. The first
case is a child who had trauma by a metal antenna of a toy with a remote
controller. The second case is another child who had what appeared to be
a minor fall at the door steps and brought to the hospital with minor lid and
corneal abrasions but with visual loss.
Results: In the first case the father cut the antenna before bringing the child to
the hospital to release the toy. The metal antenna was protruding out of the
closed eyelids and appeared at presentation to have caused severe ocular
damage. Luckily, the eye was completely untouched as the rounded end of
the antenna hooked on the lid margin without damaging the eye. In the second
case, despite the minor external abrasions, the trauma caused optic nerve
avulsion that resulted in complete and irreversible loss of vision.
Conclusions: Ocular trauma in children is a preventable cause of blindness. It
can result in devastating visual loss. Rarely, visual outcome is favourable.
