目的:观察糖尿病性白内障患者施行超声乳化联合人工晶状体植入术后视力变化及其影响因素。 方法：对42例48眼糖尿病性白内障患者及48例48眼单纯老年性白内障患者行超声乳化吸除联合人工晶状体植入术，观察术后视力及术后并发症。 结果：与对照组相比,糖尿病组术后视力较差,但两组无明显统计学差异。糖尿病组术后角膜内皮水肿、纤维素性渗出和虹膜后粘连显著增多。 结论:糖尿病患者白内障术后视力的恢复与眼底病变程度、病程及术后并发症的影响有关。

AIM:To investigate the visual acuity change and its influencing factors of diabetic cataract after phacoemulsification and intraocular lens implantation. METHODS:Phacoemulsification and intraocular lens implantation was done in 42 patients (48 eyes) with diabetic cataract and 48 senile cataract patients (48 eyes).Visual acuity and postoperative complications were observed. RESULTS：Compared with the control group, diabetic group postoperative visual acuity was poor, but the two groups was no significant difference. In the diabetic group, postoperative corneal endothelial edema, fibrinous exudation and posterior synechiae of iris increased significantly. CONCLUSION：The visual acuity after the operation was related to the diabetic retinopathy level, diabetic duration and postoperative complications.
