摘要
目的 探讨人工晶状体(IOL)囊袋复合体形态对IOL倾斜和偏心的影响.方法 前瞻性队列研究.年龄相关性白内障超声乳化联合单片折叠型IOL囊袋内植入术121例(121只眼).术后以裂隙灯采集IOL囊袋复合体形态,以Pentacam测量各组IOL偏心和倾斜的方向和程度.结果 IOL植入术后3个月,全压囊组较其余三组合组180度平面偏心量小(t=-2.020,P=0.046),部分压囊组中的鼻侧组较颞侧组在180度平面向颞侧倾斜度大(t= 2.613,P=0.021).结论 晶状体前囊膜撕囊口边缘全部位于IOL光学面上,是保证术后IOL正位的最佳复合体形态.
Abstract
Objective To investigate the influence of intraocular lens(IOL)capsular complex morphology on the tilt and decentration of IOL.Methods It was a cohort study.Ultrasound emulsification combined with single-piece folded IOL capsular bag intraoperative implantation was performed in 121 cases(121 eyes)with age-related cataract.The morphol-ogy of IOL capsular complex was collected postoperatively by the slit lamp,and the direction and degree of the decentra-tion and tilt of the IOL in each group were measured by Pentacam.Results At 3 months after IOL implantation,the decen-tration of the full compression capsule group was smaller than that of the other three combined groups(t=-2.020,P<0.05)in 180-degree plane.The tilt of the nasal group was larger to the temporal side than the temporal group in the partial com-pression group in 180-degree plane(t=2.613,P<0.05).Conclusions All the edges of the anterior lens capsule tear are lo-cated on the optical surface of the IOL,which is the best complex morphology to ensure the orthotropic position of the IOL after the operation.
