【摘要】：目的統(tǒng)計人工晶狀體取出術及置換術的臨床資料,分析人工晶狀體取出術的手術原因及置換術后療效。 方法回顧性分析本院2008年9月至2013年9月收治的133例(135眼)人工晶體取出術,統(tǒng)計患者的術前臨床特征、手術指征、取出晶狀體時間及類型、新裝人工晶狀體型號及位置,術后療效等。 結果所有患者根據是否植入新晶體分為兩組。單純人工晶體取出術84例(85眼),其中前房型人工晶狀體常因角膜內皮失代償(41%)、繼發(fā)性青光眼(30%)取出,后房型人工晶狀體眼多發(fā)生了視網膜脫離等眼底疾病(48%)；同期人工晶體置換術共49例(50眼),其中44例原晶體位于后房。置換指征依次是晶狀體移位／脫位(74%)、屈光度錯誤(10%)、人工晶狀體混濁(8%)等。取出的人工晶狀體材料以一片式疏水性丙烯酸(38%)為主,其次是聚甲基丙烯酸甲酯(26%)。白內障術后有到兩個人工晶狀體取出高峰,分別位于術后1年內和7-12年。置換術多使用一片式硬性晶狀體植入前房或虹膜固定(58%)。置換術后視力顯著提高(p0.05),未出現嚴重并發(fā)癥。 結論人工晶狀體植入后發(fā)生移位／脫位是取出的最主要原因,屈光度錯誤、人工晶狀體渾濁、角膜炎、眼內炎等并發(fā)癥比例均有所下降。置換人工晶狀體可有效處理白內障術后相關并發(fā)癥。
[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.
