Cataract is common after silicone oil repair of retinal detachment due to necrotizing retinitis in acquired immunodeficiency syndrome. Surgical management has not been reported. Twenty-two eyes of 19 patients were reviewed. The majority underwent phacoemulsification with a posterior chamber convexoplano implant without iridotomy Complications included capsular fibrosis and hyphema. Unpredictable refractions in the first 16 eyes prompted refinement of lens calculations and resulted in a reduction in refractive errors. A 3-step modification of intraocular lens calculations is recommended: (1) use of specific sound velocities to calculate axial length; (2) use of convexoplano lenses; and (3) addition of a constant to the lens power to compensate for the refractive index of silicone oil. Good surgical technique and accurate lens calculations should improve management of cataracts that arise after retinal detachment repair with silicone oil in patients with acquired immunodeficiency syndrome.
在获得性免疫缺陷综合征中，因坏死性视网膜炎导致视网膜脱离行硅油修复术后白内障很常见。尚未见手术治疗的报道。对19例患者的22只眼进行了回顾性研究。大多数患者接受了超声乳化术并植入后房型凸平人工晶状体，未行虹膜切开术。并发症包括囊膜纤维化和前房积血。最初16只眼中不可预测的屈光不正促使改进晶状体计算方法，从而减少了屈光误差。建议对人工晶状体计算进行三步修改：（1）使用特定的声速计算眼轴长度；（2）使用凸平人工晶状体；（3）在晶状体屈光度上加一个常数以补偿硅油的折射率。良好的手术技术和准确的晶状体计算应能改善对获得性免疫缺陷综合征患者行硅油视网膜脱离修复术后出现的白内障的治疗。
