改良后房型人工晶状体缝线固定术临床观察

目的：评价改良的后房型人工晶状体经巩膜缝线固定术的临床疗效。方法：将82例拟行后房型人工晶状体经巩膜缝线固定术的患者随机分成两组：改良后的无巩膜瓣线结埋藏式及经睫状体平坦部固定组;常规的有巩膜瓣经睫状沟缝线固定组。分别观察两组的手术时间、术后视力、术后并发症。结果：本研究中改良组的手术时间平均为39.95±5.87min,常规巩膜瓣组的时间平均为45.77±5.21min,两组手术时间存在显著差异。术后视力两组无显著差异。两组均未发生线结外露缝线磨损、术后眼内炎、视网膜脱离并发症。常规巩膜瓣组易出现人工晶状体光学部夹持现象。结论：改良的后房型人工晶状体经巩膜缝线固定术是一种矫正无足够后囊膜支持眼的安全、有效、简洁的术式。

Clinical observation on improvement of posterior chamber intraocular lens implantation with suture fixation

AIM:To assess the clinical effect on improvement of posterior chamber intraocular lens(IOL)implantation with transscleral suture fixation.

METHODS: Totally 82 cases were divided into two groups, one group with non-sclera flap and the pars plana location for IOL transscleral fixation of suture ends were buried into the sclera, the other group with sclera flap and the ciliary sulcus location for IOL transscleral fixation. The operation time, visual acuity and postoperative complications were compared.

RESULTS: There was significant difference in operation time between two groups. There was no significant difference in visual acuity. No cases of suture erosion, postoperative endophthalmitis, retinal detachment. Pupillary capture of the IOL optic occurred more frequently in the ciliary sulcus group with sclera flap.

CONCLUSION: Improvement of posterior chamber IOL implantation with transscleral suture fixation is a safe and effective and simple method for correction of eyes in the absence of adequate posterior capsular support.
