Excimer laser in situ keratomileusis (LASIK) is a typical surgical technique which precisely cutting cornea to rectify refractive error with excimer laser.Since the safety,stability,predictable postoperative vision affirmed,it has been accepted by multiple myopia patients in recent years.AC/A is a significant composition of visual function.Nowadays,numerous scholars have pay close attention to its transformation after LASIK,and this paper reviewed the variation trend of AC/A,the influencing factors and its possible mechanisms.%准分子激光原位角膜磨镶术(excimer laser in situ kemtomilleusis,LASIK)是一种矫正患者异常屈光状态的手术方式,它运用准分子激光对表层屈光介质进行精准切削,从而改变角膜的屈光度,使患眼恢复至正视状态,由于其安全性、稳定性好,术后效果肯定,近年来已在广大近视人群中大量推行.调节性集合比调节(accommodative convergence/accommodation,AC/A)是一项反映视功能的重要指标,近年来,已有不少学者对该项指标在LASIK术后的变化进行观察研究.我们就其变化趋势、影响因素以及可能的机制等进行综述.
