高度近视患者LASIK术前预防性光凝的临床观察

目的 观察高度近视患者LASIK术前行预防性氩离子激光光凝的疗效。方法 LASIK术前对高度近视患者常规行直接眼底镜、三面镜和间接眼底镜配合巩膜压迫法检查，对明确有周边视网膜变性或伴干性裂孔的高度近视患者42例(45只眼)行氩离子激光光凝治疗。结果 高度近视患者42例(45只眼)氩离子激光光凝术后周边视网膜变性及干性裂孔区封闭良好，色素斑形成明显。LASIK术后6个月随访，术前行氩离子激光光凝的患者视网膜情况良好，未发生裂孔源性视网膜脱离。结论 LASIK术前对明确有视网膜变性或伴干性裂孔的高度近视患者预防性行氩离子激光光凝治疗，疗效确切，是预防LASIK术后出现裂孔源性视网膜脱离的重要措施。

Clinical observation of argon laser photocoagulation before laser in situ keratomileusis on the high myopia

Objective To investigate the effect of argon laser photocoagulation before LASIK operation on the high myopia.Methods By direct ophthalmoscope,Goldmann three mirror contact lens and indirect ophthalmoscope with scleral depress examination,45 eyes of 42 high myopia were detect with peripheral retinal degeneration or retinal hole and conduct argon laser photocoagulation before LASIK operation.Results The retinal condition of 45 eyes of 42 high myopia was stable after LASIK operation by followed up 6 months.Conclusion The effect of argon laser photocoagulation before LASIK operation on the high myopia is confirmed.It's an important method to prevent retinal detachment after LASIK operation.
