摘　　要：患者男性,87岁,白内障术后右眼视物模糊10余年,查体可见角膜中央大片后弹力层皱褶,结合病史及前节OCT等辅助检查初步诊断为右眼陈旧性角膜后弹力层脱离,根据共聚焦显微镜结果判断褶皱区域无内皮细胞,于是先后行右眼后发性白内障联合残余皮质抽吸术以及右眼角膜后弹力层剪除和前房成形术,术后患者视力提高。本文结合病理检查分析了该患者大片后弹力层脱离后角膜透明的原因以及内皮代偿的方式,并总结了预防术源性角膜后弹力层脱离的要点以及注意事项。The patient,an 87 years old man,had suffered blurred vision of right eye more than 10 years from cataract surgery.Physical examination showed wide descemet’s membrane folds in the central cornea.According to medical history and auxiliary examinations such as anterior segment OCT,the patient was initially diagnosed with Descemet’s membrane detachment in right eye.Therefore,the patient decided to undergo a series of surgeries including posterior capsular phacoemulsification,residual cortex aspiration,descemet’s membrane removal and anterior chamber plasty in right eye.The patient achieved ideal visual acuity after surgical treatment.Combining with the laboratory pathological examination,this article analyzed the causes of corneal transparency after wide descemet’s membrane detachment and the ways of endothelial compensation.In addition,the key points and precautions of avoiding descemet’s membrane detachment during phacoemulsification were also summarized.
