摘要
目的：对无晶体眼并后囊膜缺损的眼行前房型人工晶体植入和缝线固定后房型人工晶体植入术进行临床对比观察，了解临床效果及并发症。方法：随机对两组病人共１６例进行手术。用美国Ｓｔｏｒｚ公司生产双侧“Ｓ”型弹性袢前房型人工晶体和ＫａｂｉＰｈａｒｍａｃｉａ“Ｃ”袢后房型人工晶体。结果：行前房型人工晶体植入术组，术后视力１０以上占３７５％（３／８），０５以上占５０．０％（４／８）。缝线固定术组无一例达１０以上者，０５以上占２５．０％（２／８）。结论：新型前房型人工晶体植入术显示有更多的优越性。从解剖学观点来说，各种缝线固定技术，很难将晶体袢通过缝线定位在睫状沟处，并对眼组织可能造成不同程度的损伤。
Objective: To identify the clinical effects and complications after anterior chamber intraocular lens (IOL) implantation and fixation of posterior chamber lens by transscleral sutures. Methods:The authors randomized 16 patients with two groups to undergo anterior chamber IOL implantation (8 patients) and posterior chamber IOL implantation (8 patients). Results: The rate of vissual acuity 1.0 was 37.5% in patients with anterior chamber IOL. There were no cases achieved a vissual acuity of 1.0 in patients with fixation posterior chamber lens. Conclusions: The results suggested that the anterior chamber IOL implantation showed more advantages. It was very difficult to fix the haptic of IOL properly into the ciliary sulcus by suturing. The high incidence and great variety of complications were associated with fixation of posterior chamber lens.
