目的:分析糖尿病性白内障患者与老年性白内障患者行超声乳化手术后两者视力不同的原因。方法:分别于术后1,2wk;3,6mo,对60眼行超声乳化白内障吸除术的糖尿病性白内障患者(糖尿病组),以及60眼行超声乳化白内障吸除术的老年性白内障患者(非糖尿病组)的手术眼行荧光眼底血管造影(FFA)检查。结果:超声乳化白内障吸除术后,非糖尿病组与糖尿病组视力改善有显著性差异。糖尿病组黄斑水肿的发生率明显高于非糖尿病组。结论:糖尿病性白内障患者行超声乳化吸除术后的黄斑水肿及因糖尿病所造成的糖尿病视网膜病变是影响术后视力的主要原因。

AIM:To analyze the reason for different of visual acuity after phacoemulsification surgery in treating diabetic cataract and senile cataract patients. METHODS:After operation,diabetic cataract patients (60 eyes,diabetic group) and senile cataract patients(60 eyes,non-diabetic group) underwent the fundus fluorescein angiography(FFA) on the postoperative week 1 and 2,month 3 and 6. RESULTS:There was significantly difference in improvement of visual acuity between non-diabetic group and diabetic group after phacoemulsification.Macular edema in diabetic group was significantly higher than that in non-diabetic group. CONCLUSION:Macular edema and diabetic retinopathy are the main reason for affecting visual acuity in patients with diabetic cataract after phacoemulsification.
