摘　　要：角膜屈光手术目前主要分为表层角膜屈光手术、板层角膜屈光手术与飞秒激光透镜取出术3大类,均广泛应用于屈光不正的矫正。虽然大多数患者在术后能够获得理想的裸眼视力,但术后高阶像差的增大往往导致眩光、重影、夜视力下降等并发症的发生。角膜屈光手术中影响高阶像差的因素非常多,笔者就角膜屈光手术类别以及角膜瓣/帽、矫正度数高低、光学区直径大小、光学区偏心程度、不同准分子激光切削模式对术后高阶像差大小的影响进行综述。At present,corneal refractive surgery is mainly divided into three categories:superficial corneal refractive surgery,lamellar corneal refractive surgery and femtosecond laser lens extraction,all of which are widely used in the correction of refractive errors.Although most patients obtain ideal uncorrected distance visual acuity after surgery,the increase of higher-order aberrations often leads to complications such as glare,ghosting,and decreased night vision.There are many factors that influence higher-order aberrations in corneal refractive surgery.This review summarized the types of corneal refractive surgery and the influencing factors of higher-order aberrations during corneal refractive surgery including corneal flap/cap,degree of correction,optical zone diameter,optical zone eccentricity,and different excimer laser ablation modes.
