周边视网膜变性光凝后LASIK手术的疗效观察

目的了解准分子激光原位角膜磨镶术(LASIK)前近视患者周边视网膜变性的发生情况,评价对其行眼底激光光凝治疗后再行LASIK手术的疗效及安全性。方法对拟行LASIK术的1015例2030只眼扩瞳后用Volk Digital WideField前置镜和三面镜详查眼底,对于囊样变性、格子样变性、干性裂孔、亚临床视网膜脱离等眼给予532nm激光预防性光凝,经随访稳定有效后再择期行LASIK手术(B组),其余未行眼底激光预防性光凝的手术患者为A组。观察两组术后1周、1和6个月、1年裸眼视力以及B组眼底情况。结果在1015例(2030只眼)中,发现周边视网膜变性共146例237只眼。A组937例1874只眼和B组72例106只眼患者LASIK手术后1周、1个月、6个月、1年裸眼视力差异无显著意义;B组患者LASIK手术后1和6个月、1年散瞳后复查眼底见视网膜病变程度稳定,变性区无进展和演化,无视网膜脱离发生。结论LASIK术前对所有患者进行详细、全面的眼底检查是十分必要的,对于有临床意义的周边视网膜变性在LASIK术前给予预防性激光光凝是安全和有效的,能够有效防止视网膜裂孔及脱离的发生,对LASIK术后的裸眼视力无明显影响。

Efficiency of 532nm Laser Photocoagulation Before LASIK Surgery

Objective To investigate the degeneration of myopia before LASIK and evaluate the efficiency and safety of treatment with 532nm laser photocoagulation.Methods LASIK was performed in 1015 consecutive patients (2030 eyes).Before operation,the funds were examined with Volk Digital Wide Field biconvex lens and three-mirror lens.The patients without 532nm laser photocoagulation were as group A with severe retinal degeneration and that with 532nm laser photocoagulation performed were as group B.The uncorrected vi...
