Results of crescentric lamellar resection in pellucid marginal degeneration

الملخص EN

Purpose; effect of lamellar crescentric resection in the .surgical treatment of pellucid marginal degeneration was evaluated.

Patients and Methods: Awe eyes in five patients with Pellucid marginal degeneration were treated by lamellar crescentric resection (full thickness resec¬tion in one eye).

Post-operative follow-up ranged from 4 to 27 months (mean 19.7).

Uncorrected vis¬ual acuity before the surgery was 20/260 to counting finger which could not be corrected because the cornea had against the rule astigmatism.

Results: Visual acuity of 20/40 or better without correction was obtained in four of nine eyes.

This amount of vision with spectacles was in 6 of nine eyes.

Conclusion: paying attention to high success rate and comparing it with other method* such as pene¬trating keratoplasty (with possibility of graft rejec¬tion), this method seems to be much better than the others.
