Lamellar crescentic resection is an effective nonpenetrating surgical treatment for pellucid marginal corneal degeneration, but the visual recovery period may be drawn out, according to an Iranian study.

Mohammad A. Javadi, MD, and colleagues at Labbafinejad Medical Center in Tehran evaluated 15 eyes of nine patients who underwent lamellar crescentic resection for the correction of pellucid marginal corneal degeneration. Preoperatively, best corrected visual acuity ranged from 20/200 to 20/500 with a mean 19 D of against-the-rule astigmatism. Follow-up ranged from 13 to 57 months.

Postoperatively, patients had with-the-rule astigmatism with a mean of 16 D at 6 weeks and 10.5 D at 6 months. During the second postop year, astigmatism declined further to 4.3 D. BCVA was 20/40 in 71% of eyes at final follow-up, and no significant complications occurred during the study period.

The study is published in the March/April issue of Journal of Refractive Surgery.
