目的:探讨虹膜夹型人工晶状体(verisyse)植入治疗外伤术后无晶状体眼的术后视功能及并发症,以期为外伤术后无晶状体眼的术式选择、手术方法提供一些临床依据。方法:回顾2006-08/2008-07来本院住院的外伤术后无晶状体眼患者42例43眼随机纳入试验组和对照组,以虹膜夹型人工晶状体植入作为试验组,晶状体悬吊作为对照组。作术后视力、角膜内皮及并发症的比较。结果:试验组所有病例术中1次固定成功,术后裸眼视力均较术前提高,最佳矫正视力均达到或接近术前最佳矫正视力。术后少数患者出现一过性高眼压、人工晶状体光学面倾斜、偏斜、脱位、眩光等并发症,所有病例中均未出现玻璃体积血、脉络膜脱离等并发症。两组术后视力、角膜内皮细胞及并发症差异无统计学意义。结论:虹膜夹型人工晶状体植入治疗外伤术后无晶状体眼具有操作简单及安全的优点。适合于无后囊、前房深浅正常及角膜内皮正常的病例。

AIM:To investigate the visual function and complications of iris-clip intraocular lens(verisyse) implanting to cure aphakic eye after trauma operation,to offer some clinical basis for the selection of surgical procedure and the ways of operation for aphakic eye after trauma operation.METHODS:A retrospective review was conducted for consecutive patients that received suture iris-clip intraocular lens(experimental group)and intraocular lens suspension(control group)for aphakic eye after trauma operation in our hospital from Aug.2006 to July.2008,and to compare the visual acuity,corneal endothelium and complications after operation.RESULTS:All cases in experimental group were fixed successfully one time,postoperative uncorrected visual acuity improved compared with before operation,the best corrected visual acuity(BCVA) came at or near the preoperative BCVA.No complications such as vitreous hemorrhage or choroidal detachment occurred.There was no significant statistical difference between two groups in visual acuity,corneal endothelium and complications after operation.CONCLUSION:The advantage of iris-clip intraocular lens(verisyse) implanting is simple to manipulate and safe and suitable for cases of lack of posterior capsule,normal depth of anterior chamber and normal corneal endothelium cells.
