【摘要】:目的:比较高度近视行飞秒激光小切口角膜基质透镜取出术(SMILE)和飞秒激光辅助的准分子激光原位角膜磨镶术(FS-LASIK)术后早期角膜高阶像差的变化。方法:前瞻性非随机对照研究。收集2018年6月至2019年2月在广西医科大学第一附属医院激光近视矫正中心行近视矫正术的高度近视患者,按手术方式分为SMILE组25例(48眼)和FS-LASIK组20例(38眼)。术前常规检查包括裸眼视力(UCVA)、最佳矫正视力(BCVA)、屈光不正度数(包括球镜、柱镜以及等效球镜)、眼压、Pentacam测量双眼角膜高阶像差,记录患者术后1天、1周、1个月时间段的裸眼视力(UCVA)、各阶角膜高阶像差以及1月时主观视觉质量调查结果。数据验证正态分布时采用独立样本t检验和单因素ANOVA方差分析,非正态分布时采用非参数Mann-Whitney U检验和Wilcoxon秩和检验进行统计学分析。结果:1.FS-LASIK组与SMILE组的有效指数为0.91±0.16和0.92±0.11,术后1月UCVA组间无明显差异(P0.05)。SMILE组组内术后UCVA 1周与1天,1月与1周之间相比提高明显,差异有统计学意义(z=-2.297,P=0.0220.05;z=-2.995,P=0.0030.05)。FS-LASIK术后UCVA随访组内无明显差异(P0.05)。2.FS-LASIK组术后1月总高阶像差RMS、倾斜三叶草差、四阶球差与术前相比增加显著,有统计学意义(P0.05),其余各随访时间点变量无明显差异(P0.05);3.SMILE组术后1月的总高阶像差RMS、垂直慧差、四阶球差与术前相比增加显著,差异有统计学意义(P0.05),术后一周与一天总高阶像差RMS增加变化量差异显著,有统计学意义(P0.05),其余各时间点变量差异不显著(P0.05)。4.两组间比较,术后1月FS-LASIK组较SMILE组总高阶像差RMS、四阶球差增加显著,SMILE组较FS-LASIK组垂直慧差增加显著,差异有统计学意义(t=-2.108,P0.05;t=-3.344,P=0.0010.05;t=-5.793,P0.05),其余各项高阶像差差异均无统计学意义(P0.05)。5.两组手术方式术后1月眼部症状以及主观视觉质量之间无明显差异(P0.05)。结论:1.SMILE与FS-LASIK矫正高度近视术后均不同程度上使角膜的高阶像差改变,FS-LASIK组总高阶像差RMS及球差较SMILE增加更加显著,SMILE垂直慧差较FS-LASIK增加更加显著。2.术后早期FS-LASIK较SMILE角膜高阶像差以及UCVA更加稳定。3.SMILE与FS-LASIK术后早期在患者主观方面均可得到较为满意的术后效果。
