Study design:

研究目的:

本研究根据 FS-LASIK 术后糖皮质激素滴眼液种类不同分组,利用 pentacam测量角膜光密度,iTrace 测量调制传递函数截止频率(MTF cut off),斯特列尔比(SR),总高阶像差 (Total HOA-RMS),低阶像差 (LOA-RMS),采集泪液进行 ELIAS 检测与蕨样变试验,对比两组上述结果差异,以期获得术后最佳激素用药方案  

Objectives of Study:

This study stratified patients into two groups based on the type of topical corticosteroid administered after FS-LASIK. We employed the Pentacam to measure corneal densitometry and the iTrace visual function analyzer to assess optical quality metrics, including the modulation transfer function cutoff (MTF cut off), Strehl ratio (SR), total higher-order aberrations (Total HOA-RMS), and lower-order aberrations (LOA-RMS). Additionally, tear samples were collected for cytokine level quantification via ELISA and for fern pattern testing. The aforementioned parameters were then compared between the two groups to identify the optimal postoperative corticosteroid regimen.
