To assess the results of a modified technique for scleral fixation of a posterior chamber intraocular lens (IOL) in eyes which had deficient of posterior capsular support.
This retrospective study was comprised of ten patients with deficient posterior capsular support who underwent one-haptic fixation of posterior chamber IOLs, between February 2010 and October 2011. IOL as implanted with one haptic supported on the capsular remnant and the other haptic drawn into the sulcus by anchoring suture without a knot. All patients were evaluated for pre- and postoperative visual acuity, lens centration, intra-and postoperative complications.
A knotless, one-haptic fixation of posterior chamber IOLs has successfully been performed on ten eyes. All cases had inadequate capsular support (i.e. a capsular tear ranged from 5 to 7 clock hours). The average age was 74.25±8.87y (SD). The average postoperative uncorrected visual acuity was 0.51 logMAR. Complications included hyphema in one eye, a mild inflammatory reaction in the anterior chamber in two eyes, and a transient rise in IOP in one eye. Neither IOL tilt nor dislocation was observed and there were no later complications.
In the presence of insufficient capsular support, a knotless, one-haptic fixation of posterior chamber IOLs is a safe and viable option which reduces the operation time, and minimizes postoperative suture-related complications.
评估一种改良技术用于在缺乏后囊膜支撑的眼中进行后房型人工晶状体(IOL)巩膜固定的效果。
这项回顾性研究纳入了2010年2月至2011年10月期间接受后房型IOL单袢固定术的10例后囊膜支撑不足的患者。IOL植入时,一个袢支撑在囊膜残余上,另一个袢通过锚定缝线拉入睫状沟且不打结。对所有患者进行术前和术后视力、晶状体中心定位、术中及术后并发症评估。
已成功对10只眼进行了后房型IOL的无结单袢固定。所有病例的囊膜支撑均不足(即囊膜撕裂范围为5至7个钟点)。平均年龄为74.25±8.87岁(标准差)。术后平均未矫正视力为0.51 logMAR。并发症包括1只眼发生前房积血,2只眼前房出现轻度炎症反应,1只眼眼压短暂升高。未观察到IOL倾斜或脱位,且无后期并发症。
在囊膜支撑不足的情况下,后房型IOL的无结单袢固定是一种安全可行的选择,可缩短手术时间,并将术后缝线相关并发症降至最低。
