目的：探讨白内障超声乳化术后角膜水肿的相关因素。 方法：通过观察532例564眼白内障超声乳化术后第1d角膜水肿的情况，分析角膜水肿与年龄、核硬度、合并青光眼、糖尿病的关系。 结果：患者564眼中角膜水肿共计118眼，发生率为209%。其中70岁以上角膜水肿占24.0%，Ⅳ级核占36.9%，Ⅴ级核为100%。其中抗青光眼术后白内障角膜水肿比例为68.1%，合并有糖尿病白内障角膜水肿比例为48.6%。 结论：白内障超声乳化术后角膜水肿程度与年龄、核硬度程度呈平行关系；糖尿病和抗青光眼术后的患者角膜容易发生水肿反应，反之无眼部手术病史、糖尿病史患者术后角膜水肿发生率低，水肿反应轻。

AIM:To analyze the correlative factors of the corneal edema after cataract phacoemulsification. METHODS:The relations between the corneal edema and age,rigidity of lens nucleus,glaucoma, diabetes in 532 cases (564 eyes) after cataract phacoemulsification were studied. RESULTS:There were 118 eyes of corneal edema in 564 eyes, the rate of corneal edema was 20.9%. The incidence of patients older than 70 was 24.0%,Ⅳ level of lens nucleus was 36.9%,Ⅴ level of lens nucleus was 100%, patients with operation for glaucoma was 68.1%, and patients with diabetes was 48.6%. CONCLUSION:Corneal edema after cataract phacoemulsification surgery has parallel correlation with age and rigidity of lens nucleus. Its easy to occur in patients with diabetes or operation for glaucoma.While, patients with no ocular operation, diabetes mellitus have a lower rate of corneal edema and lighter reaction.
