超声乳化联合前段玻璃体切割治疗白内障晶体半脱位

目的:探讨超声乳化联合前段玻璃体切割囊袋内人工晶体植入治疗白内障晶体半脱位临床疗效及可行性.方法:选取因外伤伴有晶状体半脱位的白内障患者36例(36只眼).患者首先做常规白内障透明角膜切口,撕囊、水分离、超声乳化晶状体吸出,同时切除溢出到前房的玻璃体,囊袋内植入人工晶体.结果:36例(36只眼)患者均顺利摘除浑浊的晶状体,成功地保留了后囊膜,并在囊袋内植入了人工晶体,28例患者人工晶体位置较正,8例略向下移位.术后视力0.1~0.5者24例;0.5~1.0者11例;1例失明(均随访半年).结论:超声乳化吸出联合前段玻璃体切割囊袋内人工晶体植入手术治疗晶状体半脱位的白内障是一种安全、有效的手术方式.

Effect of Phacofragmentation Combined Previous Vitrectomy on Lens Semi-dislocation

Objective:To investigate the feasibility and effect of the therapy of lens semi-dis-locating by phacofragmentation combined previous vitrectomy.Methods:36 eyes of 36 patients with lens semi-dislocation were observed.The patients underwent conventional phacofragmentation with transparent corneal incision.The previous vitrectomy was done when the vitreous out flowed into anterior chamber.The postoperative visual change and complications were observed.The mean fellow-up period was 6 months.Results:All the patients had the cataract removed,maintained complete posterior capsular and the intraocular lens were implanted.In 28 eyes the position of arti-ficial lens was in right position,8 eyes were observed intraocular lens decentration.24 eyes have a visual acuity from 0.1 to 0.5,11 eyes have a visual acuity from 0.5 to 1.0,1 eye is blind.Con-clusion: The method to treat lens semi-dislocation by phacofragmentation combined anterior vit-recotemy is feasibility and effective.
