准分子激光原位角膜磨镶术治疗近视并发症的分析

目的:探讨准分子激光原位角膜磨镶术(LASIK)治疗近视并发症的预防和处理措施.方法:500例(1 000眼)近视患者(-0.751D～-15.00D)行LASIK.术后随诊12个月,观察并分析其并发症.结果:术中负压吸引失败5眼(0.5%),角膜瓣形成不全6眼(0.6%),游离瓣12眼(1.2%),角膜血管翳出血28眼(2.8%),角膜瓣层间异物残留20眼(2%),角膜上皮内生及植入7眼(0.7%),结膜下出血160眼(16%),术后眩光及夜驶困难26眼(2.6%).偏心切削40眼(4%),中央视岛形成5眼(0.5%),弥漫性板层角膜炎DLK8眼(0.8%),青光眼2眼(0.2%),感染2眼(0.2%),术后屈光欠矫或过矫1.00D者50眼(5%).结论:LASIK治疗近视安全有效,但仍存在并发症,有提高手术技巧和完善手术设计的必要性.

Complications of excimer laser in situ keratomileusis for myopia

Objective:To analyze the complications of excimer laser in situ keratomileusis for myopia.Methods:LASIK was run on 1000 eyes in 500 patients with myopia.All of them were fallowed up for a period of 12 months.Results: In 1000 eyes,there was intraoperative inadequate suction in 5 eyes(0.5%),incomplete cap in 6 eyes(0.6%),free cap 12 eyes(1.2%),corneal pannus hemorrhage 28 eyes(2.8%),interface debris 20 eyes(2%).epithelial in growth and implantation 7 eyes(7%).Sudconjunctival hemorrhage 160 eyes(16%).postoperative night glare 26 eyes(2.6%).eccentric ablation(>0.5 mm) 4 eyes(4%).Central insland 5 eyes(5%) undercorrection and over-correction(>1.00 D)50 eyes(5%) DLk 8 eyes(0.8%) Glucoma 2 eyes(0.2%) intection 2 eyes(0.2%).Conclusion:Lasik was a safe and effective method for correcting myopia,although there were complications.
