超声乳化白内障手术中角膜后弹力层脱离的原因及处理

Reasons and treatment methods of corneal descemet membrane detachment during phacoemulsification

目的:分析超声乳化白内障手术中致角膜后弹力层脱离的原因,探讨预防及处理方法。方法:对我院2010-01/12间954例白内障超声乳化白内障摘除联合人工晶状体植入术中87例87眼各种原因造成的角膜后弹力层脱离的临床资料进行回顾性分析。结果:87例87眼发生不同程度的角膜后弹力层脱离,5例严重脱离,经穿刺注入气泡等处理后效果满意。结论:白内障手术中切口的方式、宽度、位置及手术器械的机械性损伤,患者角膜可能存在的病理改变,是造成角膜后弹力层不同程度的脱离的主要原因,术中早期发现和及时正确的处理,对预防术后并发症及视力的恢复均起到重要作用。
