Objective To observe and compare the short-term change of morphology of regenerated subbasal nerve fiber after the femtosecond laser and keratotome for laser in situ keratomileusis(LASIK) using confocal microscope.Methods In this study,40 patients(80 eyes) with refractive error were randomly divided into 2 groups: femtosecond laser was used for LASIK myopic surgery in 20 patients(40 eyes),and keratotome was used in the other 20 patients(40 eyes).The morphology of corneal subbasal nerves was observed with co...

准分子激光原位角膜磨镶术(laser in situ kera-tomileusis,LASIK)是目前角膜屈光手术中的主流术式,角膜瓣的制作是该手术的关键。传统微型角膜刀制作角膜瓣可能出现纽扣瓣、碎瓣等并发症。2003年美国FDA正式批准飞秒激光用于眼科临床,由于飞秒激光制作的角膜瓣预测性、可控性?
