The course of diabetic retinopathy following extracapsular cataract extraction with posterior chamber lens implantation in eyes previously treated by laser photocoagulation for diabetic retinopathy was retrospectively studied in 33 eyes (33 patients). In 20 eyes (61%) there was no change in the retinal status postoperatively. In 13 (39%) there was postoperative progression of diabetic retinopathy compared with the fellow non-operated eye, in which progression occurred in nine eyes (27%). The severity of the preoperative status affected the incidence of progression. Four eyes (12%) developed complications of diabetic retinopathy--that is, rubeosis iridis and vitreous haemorrhage--which regressed after lasering. Cystoid macular oedema developed in 13 eyes (39%) and its incidence varied according to the postoperative course of diabetic retinopathy. The majority of the eyes showed a postoperative improvement in vision.
对33例患者的33只眼睛进行了回顾性研究，这些眼睛之前因糖尿病性视网膜病变接受过激光光凝治疗，之后接受了囊外白内障摘除联合后房型人工晶状体植入术。术后，20只眼睛（61%）的视网膜状况无变化。13只眼睛（39%）的糖尿病性视网膜病变较未手术的对侧眼出现术后进展，其中9只眼睛（27%）出现进展。术前状况的严重程度影响进展发生率。4只眼睛（12%）发生糖尿病性视网膜病变并发症，即虹膜红变和玻璃体出血，激光治疗后消退。13只眼睛（39%）发生黄斑囊样水肿，其发生率根据糖尿病性视网膜病变的术后病程而异。大多数眼睛术后视力改善。
