Lasik治疗屈光不正术中并发症的临床分析

目的：分析Lasik手术中并发症发生的原因和预防处理措施。方法：应用Schwind Supratome微型角膜切开刀和Lasersight LSX型准分子激光对232例448眼行Lasik手术。结果：并发症有游离角膜瓣2眼（0．45％），角膜瓣形成不全4眼（0．9％），结膜下出血195眼（43．53％），角膜血管翳出血9眼（2％），角膜瓣位置信离4眼（0．9％），薄角膜瓣2眼（0．45％），角膜层间异物残留18眼（4．01％）。结论：Lasik治疗屈光不正安全有效，手术技巧提高和熟练掌握机器的性能有助于减少并发症和增加手术的安全性。

The clinical analysis of the complications of laser in situ keratomileusis for ametropia

Objective:To analyze the causes of the complications of excimer laser in situ keratomilusis (Lasik)during operation as well as how to prevent and treat the complications.Methods:Lasik was performed on 232 patients (448eyes)with Schwind supratome and Lasersight LSX excimer laser.Results:The complications included:(1)free corneal cap,2 eyes(0.45%);(2) incomplete corneal cap,4 eyes (0.9%);(3)corneal limbal vascular pannus bleeding,9 eyes (2%);(4)subconjunctival hemorrahage,195 eyes (43.53%);(5)decentral flap,4 eyes (0.9%);(6)thin flap,2 eyes (0.45%);(7)corneal interface foreign bodies,18 eyes(4.01%).Conclusion:Although Lasik has been demonstrated to be a safe and effective way in correcting the ametropia,the development of the ophthalmologist's techniques is helpful in reducing the complications and increasing the safety of Lasik.
