[摘要]目的：分析飛秒激光小切口角膜基质透镜取出术(Small incision lenticule extraction，SMILE)和飞秒制瓣激光辅助原位角膜磨镶术(Femtosecond assisted laser in situ keratomileusis，FS-LASIK)对近视患者角膜厚度和角膜知觉的影响。方法：回顾性收集2017年7月-2019年12月笔者医院眼科收治的行SMILE治疗的25例近视患者临床资料为SMILE组，另择同期行FS-LASIK治疗的25例近视患者临床资料为FS-LASIK组。比较两组术前和术后1周等效球镜度、角膜曲率、角膜厚度、不同位置角膜知觉，两组术后1周中央区角膜帽厚度、全区角膜帽厚度和并发症发生情况。结果：术后1周，两组等效球镜度较术前升高，SMILE组高于FS-LASIK组，差异有统计学意义(P0.05)。结论：与FS-LASIK相比，SMILE治疗近视能显著改善患者视力、角膜曲度和角膜厚度，其制作的角膜帽厚度更薄，对患者角膜知觉损伤更小，同时并发症较少。
