３０例（４７只眼）糖尿病性白内障施行囊外白内障摘除及人工晶体植入术，其手术并发症与非糖尿病人无差异，唯术后视力差异有显著性。影响糖尿病患者术后视力的主要原因是增殖性视网膜病变（Ｐ＜０．００１）。糖尿病组未合并糖尿病性视网膜病变及合并单纯性糖尿病性视网膜病变与非糖尿病组差异无显著性（Ｐ＞０．０５），提示糖尿病合并增殖性视网膜病变的患者做白内障摘除及人工晶体植入术应当谨慎。
30 cases (47 eyes) of diabetic cataract were treated by extracapsular cataract extraction and intraocular lens implantation. There was no difference between the surgical complications and non-diabetic patients. The differences of postoperative visual acuity were significant. The main cause of postoperative visual acuity in diabetic patients is proliferative retinopathy (P <0.001). Diabetic patients without diabetic retinopathy and simple diabetic retinopathy and non-diabetic patients showed no significant difference (P> 0.05), suggesting that diabetic patients with proliferative retinopathy and cataract extraction and intraocular lens implantation Be cautious.
