Abstract Details


To evaluate the corneal endothelial cell density and hexagonality one year after laser assisted keratomileusis using mitomycin C.


Imam Hossein Medical Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran.


One hundred and three eyes from 52 patients who underwent laser assisted sub-epithelial keratomileusis using mitomycin C 0.02% for 15 to 30 seconds entered this study. Corneal endothelial cells were evaluated using specular microscopy before and one year after the surgery considering endothelial cell density and hexagonality. Also the corneal thickness was measured before and one year after the surgery.


The mean endothelial cell density before surgery was 2870±368/mm2 which changed to 2828±30/mm2 one year after the surgery (p=0.182). Polymegathism was 24±7 before the surgery which changed to 25±7 one year after the surgery (p<0.039).The average stromal ablation debt was 65 micron (22 to 131 micron) and the remaining corneal thickness one year after the surgery was 488±2 micron (405 to 567 micron) (p<0.001).


Using mitomycin C (0, 02% for 15 to 30 seconds) during the laser assisted sub-epithelial keratomileusis did not significantly change the corneal endothelial cell density one year after the surgery but the change in polymegathism was significant. FINANCIAL INTEREST: NONE
