摘要

【正】AIM:To determine the effect of suction duration on thickness and diameter of corneal flap created by microkeratome in porcine eyes in laser in situ keratomileusis (LASIK). METHODS:Sixty porcine eyes were randomly assigned to three groups according to different suction durations:group 1 (10 seconds),group 2(20 seconds),and group 3(30 seconds).A Moria M2 microkeratome(Moria,France)with a 160μm head was used to create a corneal flap.Corneal flap thickness was measured by automated ultrasonic pachymetry, and the flap diameter was measured by a vernier caliper. RESULTS:The flap thickness of group 1,group 2 and group 3 was(146.05±13.46)μm,(157.35±18.95)μm and (169.25±21.02)μm,respectively.There was a statistically significant difference among three groups(P=0.001).The mean flap diameter in groups 1,2 and 3 was(8.63±0.19)mm, (8.89±0.24)mm and(9.06±0.18)mm,respectively.A statisti-cally significant difference was found among groups (P【0.01). CONCLUSION:In LASIK in porcine eyes,an increase in suction duration resulted in a thicker and greater flap.
