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209%。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. Its 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.
