EFFECT OF ARCUATE INCISION ON POST-KERATOPLASTY ASTIGMATISM

Abstract

This work is a report 0/9 cases ofarcuate incision for correction 0/astigmatism, after penetrating keratoplasty. Plannings were based OJJ corneal topography, and the first operation was always arcuate incision alone. 11,e secondary plans were based on refractive errors. The mean of preoperative astigmatism was 6D with the range of5 to 9/). After arcuate incision a/the graft-host interface in the firs' operation, 'he mean reduction ofastigmatism was 3. OS/) with the range 0[0.5- 4.5]). Mean spherical equivalent change was O.16D. Arcuate incision is an appropriate methodfor correction ofastigmatism after PK and can he considered a.s a single procedure for [ow astigmatism, although the results may be unprediaable:
