     【摘要】 目的 评价半脱位晶状体超声乳化术中植入囊袋张力环(CTR)的应用效果。方法 对11例(12眼)半脱位晶状体行白内障手术,术中连续环形撕囊后植入囊袋张力环,,对晶状体半脱位范围>1/2圆周者,将囊袋张力环用缝线固定在悬韧带离断一侧巩膜壁上,随后行白内障晶状体超声乳化术,囊袋内植入折叠式人工晶状体。结果 12眼晶状体半脱位白内障患者,均顺利植入了囊袋张力环及后房型人工晶状体。术后患者视力均得以提高,人工晶状体位正,无明显手术并发症。结论 囊袋张力环可提高晶状体超声乳化术的安全性,可防止人工晶状体偏位,减少手术并发症。

    【Abstract】 Objective To evaluate the efficiency of capsular tension ring implantation during phacoemulsification in the subluxated lens.Methods Capsular tension ring was implantedin 11 cases(12eyes)of subluxated lens after continuous curvilinear Capsulorrhexis during phacoemulsiifcation.The capsular tension ring was necessary to be fixmed on sclera if the luxated area was lager than half of acircle.Afterthe ring was implanted,phacoemulsification was performed and foldable intraocularlens(IOL)was implanted.Results All cases were smoothly implanted capsular tension ring and IOL.After the operations,all cases had improved visual acuity,right position of IOL,No seirous complications happened.Conclusion Capsular tension ring implantation could improve the safety of phacoemulsiifcation.It can prevent the lOL deviation and decrease the surgerial complications ......
