超声乳化白内障吸除术治疗慢性肾功能衰竭并发白内障的临床研究

目的 探讨超声乳化白内障吸除人工晶状体植入术治疗慢性肾功能衰竭（肾衰）并发白内障的疗效和手术要点。方法 对12例（23只眼）慢性肾衰进行维持性透析治疗的并发白内障患者，行超声乳化白内障吸除人工晶状体植入术；术前1d和术后第2d行血液透析或腹膜透析治疗；术前停用肝素，并给予止血药物。观察术后视力，角膜、前房和眼底情况。结果 术后1或2周裸眼视力≥0.5者20只眼（87%）；术后1个月裸眼视力稳定在1.0以上者12只眼（52%）。无严重并发症发生。结论 超声乳化白内障吸除人工晶状体植入术是治疗肾衰并发白内障患者较理想的方法；预防术中、术后出血和防治全身并发症是手术医生不可轻视的问题。

Phacoenulsitication and intraocular lens implantation in patients with chronic renal failure and eataract

Objective To report the experience in treatment of phacoemulsification and intraocular lens implantation and to evaluate its efficacy in patients with chronic renal failure and cataract. Methods Twelve patients with chronic renal failure, maintenance dialysis and cataract were treated with phacoemulsification and intraocular lens implantation in 1998 1999. The original disease of renal failure was non diabetic. The average age was 51 years, and the average time course on dialysis was 6 12 months. All the patients were stable on maintenance dialysis, and the blood pressure was controlled in or near normal range. Before the operation, the administration of heparin was stopped, and the hemostatic drug was applied. Results All the procedures were performed on 23 eyes of these patients without any complications. The naked visual acuity after operation improved significantly in comparison with that before the operation. At the postoperative one month of follow up, the visual acuity of 52% of the surgical eyes was above 1 0. Conclusion Phacoemulsification and intraocular lens implantation is effective and safe in chronic renal failure patients with cataract.
