两种角膜屈光手术矫正近视及散光术后干眼情况比较

Comparison of Dry Eye Outcomes After SMILE and FS-LASIK for Myopia and Astigmatism

目的对比全飞秒激光小切口角膜微透镜取出术(SMILE)与半飞秒激光制瓣联合准分子激光(FS-LASIK)两种手术方式治疗近视及散光术后的干眼情况。方法选取2017年9月-2018年9月我院近视中心行激光治疗近视的患者68例,分为SMILE组及FA-LASIK组,两组患者分别进行相应的激光治疗近视手术,进行为期6个月的随访,比较两组手术术后的泪膜破裂时间(TBUT)及泪液分泌量(SchirmerI试验)。结果结果显示,两组患者术后早期的泪液分泌情况与泪膜破裂时间均比术前显著下降,随时间延长有逐步恢复的迹象。而FS-LAISK的TBUT及泪液分泌情况均显著低于SMILE组,两者间有显著差异(P<0.05)。结论 SMILE手术与FS-LASIK相比,对术后干眼影响更小。

Objective To compare the dry eye situations after femtosecond laser small incision lenticule extraction(SMILE) and femtosecond laser in situ keratomileusis(FS-LASKI) for myopia. Methods 68 myopic patients in our hospital from September 2017 to September 2018 were selected and divided into SMILE group(38 cases) and FS-LASIK(30 cases).SMILE group was underwent SMILE surgery while FS-LASIK group was underwent FS-LASIK surgery. The tearbreak-up-test(TBUT) and Schirmer I test at 1-month, 3-month and 6-month after surgery were compared between the two group. Results The results that TBUT and Schirmer I test were both significantly lower than preoperative levels in both groups and recovered over time. Both of them recovered faster in SMILE group than in FS-LASIK group and the difference is significant(P<0.05). Conclusion SMILE surgery is better than FS-LASIK surgery in the matter of dry eye.
