Modified surgical technique for repeated epikeratophakia surgery in aphakic eyes.
BACKGROUND
Incomplete epithelial removal from the peripheral keratectomy at the time of repeat epikeratophakia surgery can lead to interface downgrowth and consequent failure, as observed in the case reported herein. We present a modification of the standard surgical technique aimed at avoiding such complication.


METHODS
A 69-year-old white female underwent a third aphakic epikeratophakia modified to reduce the risk of epithelial interface downgrowth, which had caused a previous failure. The aphakic tissue lens, 8.5 mm in diameter, was sutured into a corneal pocket obtained at a deeper level, inside the peripheral keratectomy used for the previous two procedures.


RESULTS
Useful visual acuity (20/60) was obtained and the refractive outcome remained stable up to 1 year postoperatively. Epithelial interface downgrowth did not recur.


CONCLUSIONS
Despite the possible risk of perforation while undermining the recipient cornea at a deeper level, the modified technique might offer a more effective method of preventing epithelial downgrowth after repeat epikeratophakia surgery.
