摘要
目前飞秒激光在角膜屈光手术的应用主要有两类,飞秒激光制作角膜瓣联合基质面行准分子激光切削（FS-LASIK）以及全飞秒激光手术;后者可分为飞秒激光基质透镜切除术（FLEx）和飞秒激光小切口基质透镜切除术（SMILE）.本文回顾了与传统LASIK相比,FS-LASIK手术后裸眼视力、矫正视力、安全指数、有效指数的差别,FS-LASIK术后对比敏感度、高阶像差等客观视觉质量以及主观视觉质量问卷的影响;与FS-LASIK相比,FLEx对术后裸眼视力、波前像差等客观视觉质量以及主观满意的影响;并对三种手术方式的术后的安全性、有效性、可预测性以及在角膜知觉方面的优缺点进行综述.
Currently,the femtosecond laser surgeries can been classified into two main groups by the application in corneal refractive field,the femtosecond laser in situ keratomileusis （FS-LASIK） and allin-one femtosecond laser refractive surgery.The latter one can be assorted into femtosecond lenticule extraction （FLEx） and small incision lenticule extraction （SMILE）.This article reviews the differences of uncorrected visual acuity （UCVA）,best corrected visual acuity （BCVA）,safety index and efficacy index between the FS-LASIK and traditional LASIK,the influence of FS-LASIK to the objective visual quality,such as contrast sensitivity and high order aberration and subjective visual quality,by comparison with FS-LASIK,the effects of FLEx on subjective visual quality,such as UCVA,wavefront aberrations and objective satisfaction.Meanwhile,the safety,efficacy,prediction and the affection on the corneal sensitivity of the three surgeries are summarized.
