Abstract:

目的 探讨聚乙二醇滴眼液对准分子激光上皮下角膜磨镶术(LASEK)后角膜雾状混浊(haze)影响的临床研究。方法 回顾性分析2009年3月-2010年3月行LASEK的患者45例90只眼的临床资料。患者屈光度(?4.68±2.30)D(?1.75~?6.50D),随机分为聚乙二醇滴眼液组(试验组)和对照组,术后定期随访观察两组角膜haze形成、角膜上皮愈合时间、视力恢复情况及屈光度。结果 术后1、3、6个月,两组haze形成差异无统计学意义(P>0.05),试验组术后第1、3、5天角膜刺激症状明显轻于对照组(P<0.05),上皮愈合速度较对照组更快(P<0.05)。结论 LASEK术后应用聚乙二醇滴眼液虽然能减轻术后患者角膜刺激症状,能促进角膜上皮更快愈合,但是不能减轻haze的形成。
