Visual quality after epipolis laser <i>in situ </i>keratomileusis surgery in mild and moderate myopia

Abstract

AIM: To comprehensively evaluate of visual quality after epipolis laser in situ keratomileusis(EPI-LASIK)in mild to moderate myopia.METHODS: Sixty cases(120 eyes)undergone EPI-LASIK with equivalent diopter(SE)were divided into two groups: mild myopia group(60 eyes)and moderate myopia group(60 eyes). Objective visual acuity, aberration, contrast sensitivity and glare sensitivity were measured before and 1wk; 1, 6mo after operation, and made comparative analysis. RESULTS: Postoperative uncorrected visual acuity(UCVA)of two groups were better than that of preoperative(PPPPPPPCONCLUSION: Visual quality is poorer in mild myopia patients than that in moderate myopia at early stage after EPI-LASIK. Better visual quality is observed at mid-late stage.
