葡萄膜炎并发白内障的超声乳化术疗效观察

Phacoemulsification and posterior chamber intraocular lens implantation in uveitic cataract

目的寻求一种对葡萄膜炎伴粘连性小瞳孔白内障的摘出更有效的手术方法。方法对６２例（６８只眼）小瞳孔白内障患者施行超声乳化联合人工晶状体植人术，随访３～１２个月。结果术后６８只眼瞳孔基本圆，９４．１％的患者视力有不同程度的改善，随访３个月以上的６１只眼中，５２只眼视力＞０．５。术中后囊破裂４例，术后角膜水肿２３例，瞳孔纤维渗出膜４例。结论粘连性小瞳孔白内障采用超声乳化吸出术，能获得良好的视力和圆瞳孔，能减轻对虹膜的刺激、损伤，减少术中、术后并发症。

Objective To evaluate the safety and efficacy of phacoemulsification for uveitic cataract. Methods 68 consecutive eyes of 62 patients with various causes of uveitis received posterior chamber intraocular lens implantation following scleral tunnel incision and phacoemulsification for visually disabling cataract. The safety and efficacy of operation were studied prospectively. Result Visual acuity was improved in 94. l% in a few days after surgery and the final visual acuity was 0. 5 or better in 52 eyes. Intraoperative complication was a posterior capsular break (4 eyes ). Postoperative complications were minimal corneal edema(23 eyes ), fibrinous pupillary membrane (4 eyes ). Conclusion Phacoemulsification can be carried out in patients with visually disabling uveitic cataract.
