目的评价糖尿病患者后房型人工晶状体植入术的手术时机及白内障囊外摘出（ＥＣＣＥ）与超声乳化白内障摘出（ＰＨＡＣＯ）两种不同术式植入后房型人工晶状体后的并发症和手术效果。方法随机选择近２年来糖尿病患者行白内障囊外摘出（２８眼）及超声乳化白内障搞出（２２眼）两种不同术式植入后房型人工晶状体后的４８例（５０眼）进行随访分析３～１９个月。结果４８例糖尿病患者包括术前空腹血糖高于正常者均安全完成手术。术后平均裸眼视力恢复３０． ５者为 ６０％，其中 ＰＨＡＣＯ组优于 ＥＣＣＥ组。术后主要并发症人工晶状体表面色素沉着、虹膜后粘连及黄斑囊样水肿发生率，ＰＨＡＣＯ组明显低于 ＥＣＣＥ组。结论只要把握好手术时机，尽量减少术后并发症，尤其是采用小切口超声乳化术，多数糖尿病患者可获得满意效果。
Objective To evaluate the timing of surgery for posterior chamber intraocular lens implantation in patients with diabetes mellitus and the complications and surgical outcomes after implantation of posterior chamber intraocular lenses (ECCE) and phacoemulsification cataract extraction (PHACO). Methods Forty-eight patients (50 eyes) with diabetes underwent extracapsular cataract extraction (28 eyes) and phacoemulsification cataract (22 eyes) underwent two types of surgery. ~ 19 months. Results 48 cases of diabetic patients, including preoperative fasting blood glucose were higher than normal safety of surgery. Postoperative average naked eye vision recovery 30. 5 were 60%, of which PHACO group was superior to ECCE group. Postoperative major complications of intraocular lens surface pigmentation, posterior synechia and macular cystoid edema incidence, PHACO group was significantly lower than the ECCE group. Conclusion As long as the timing of surgery, minimize postoperative complications, especially with small incision phacoemulsification, most diabetic patients can get satisfactory results.
