Abstract： 目的:比较应用飞秒激光制瓣准分子激光原位角膜磨镶术(FS-LASIK)与750Hz切削频率和智能脉冲技术(SPT)的经上皮准分子激光屈光性角膜切削术(TransPRK)矫正中度近视的临床效果.方法:采用非随机前瞻性队列研究.纳入FS-LASIK治疗的患者48例90眼和TransPRK治疗的患者47例90眼.所有眼睛都是中度近视(等效球镜度-3.00～-6.00D).FS-LASIK和TransPRK均由Schwind Amaris 750S准分子激光器进行.分别于术前及术后6mo对视力、等效球镜度及各项角膜高阶像差等变量进行分析,评估手术疗效.结果:术后6mo,FS-LASIK和TransPRK术后等效球镜度呈正视并相对稳定.术前和术后两组间术眼SE比较均无差异(P>0.05).术后6mo,FS-LASIK组和TransPRK组患者的总高阶像差、球差及垂直彗差均较术前明显增加(均P<0.001),且FS-LASIK组患者的总高阶像差及垂直彗差高于TransPRK组(均P<0.001).术后6mo,FS-LASIK组和TransPRK组平均疗效指数分别为1.054±0.172和1.082±0.147(t=-0.755,P=0.459).术后6mo,FS-LASIK组平均安全性指数为1.009±0.114,明显低于TransPRK组的1.124±0.213(t=-2.322,P=0.033).结论:FS-LASIK和SPT引导的TransPRK术后远期视力均较好.FS-LASIK组患者的总高阶像差及垂直彗差高于TransPRK组,且FS-LASIK安全性指数低于TransPRK.
