【摘要】：目的统计人工晶状体取出术及置换术的临床资料,分析人工晶状体取出术的手术原因及置换术后疗效。方法回顾性分析本院2008年9月至2013年9月收治的133例(135眼)人工晶体取出术,统计患者的术前临床特征、手术指征、取出晶状体时间及类型、新装人工晶状体型号及位置,术后疗效等。结果所有患者根据是否植入新晶体分为两组。单纯人工晶体取出术84例(85眼),其中前房型人工晶状体常因角膜内皮失代偿(41%)、继发性青光眼(30%)取出,后房型人工晶状体眼多发生了视网膜脱离等眼底疾病(48%)；同期人工晶体置换术共49例(50眼),其中44例原晶体位于后房。置换指征依次是晶状体移位／脱位(74%)、屈光度错误(10%)、人工晶状体混浊(8%)等。取出的人工晶状体材料以一片式疏水性丙烯酸(38%)为主,其次是聚甲基丙烯酸甲酯(26%)。白内障术后有到两个人工晶状体取出高峰,分别位于术后1年内和7-12年。置换术多使用一片式硬性晶状体植入前房或虹膜固定(58%)。置换术后视力显著提高(p0.05),未出现严重并发症。结论人工晶状体植入后发生移位／脱位是取出的最主要原因,屈光度错误、人工晶状体浑浊、角膜炎、眼内炎等并发症比例均有所下降。置换人工晶状体可有效处理白内障术后相关并发症。
[Abstract]:Objective to analyze the clinical data of intraocular lens extraction (IOL) and intraocular lens replacement (IOL). Methods from September 2008 to September 2013, 133 cases (135 eyes) of intraocular lens extraction were retrospectively analyzed. The preoperative clinical features, surgical indications, time and type of lens extraction, the type and location of new intraocular lens were analyzed. Curative effect after operation. Results all patients were divided into two groups according to the implantation of new lens. Eighty-five eyes of 84 patients underwent intraocular lens extraction, in which anterior chamber intraocular lens was often removed due to corneal endothelial decompensation and 41%, and secondary glaucoma was 30%. Retinal detachment and other fundus diseases often occurred in posterior chamber intraocular lens (IOL) eyes, and 49 cases (50 eyes) underwent intraocular lens replacement (IOL) in the same period, among which 44 cases were located in posterior chamber. The index of replacement was lens displacement / dislocation (74%), diopter error (10%), intraocular lens opacity (8%) and so on. The main IOL material was one hydrophobic acrylic acid 38, followed by poly (methyl methacrylate). There were two peaks of intraocular lens extraction after cataract surgery, within 1 year and 7-12 years after cataract. One piece of hard lens implantation in anterior chamber or iris fixation is often used for replacement. The visual acuity was significantly improved after replacement (P 0.05) without serious complications. Conclusion displacement / dislocation after intraocular lens implantation is the main reason for removal. The rate of complications such as lens opacity, keratitis, endophthalmitis and other complications are all decreased due to wrong diopter, intraocular lens opacity, keratitis and endophthalmitis. Intraocular lens replacement can effectively deal with postoperative complications of cataract.
