Abstract

Purpose: To describe the technique of modified girth-hitch suture for one-side transscleral fixation to rescue a single-haptic dislocation.

Methods: In this surgical technique report, dislocated scleral-fixated posterior-chamber intraocular lenses (IOLs) were secured to the sclera using a 10-0 polypropylene suture looped around the IOL haptic. Three types of IOL were secured in this study (four cases of one-piece polymethyl methacrylate (PMMA) IOL, one case of three-piece acrylic IOL with PMMA loop, and one case of acrylic foldable IOL with a two-plate loop design).

Results: Six patients, who had subluxation of the scleral-fixated posterior-chamber IOL due to single-knot dehiscence, underwent refixation of scleral-fixated IOL surgery using this technique. In all cases, successful repositioning with stable and central fixation of the IOLs was achieved. No intraoperative or postoperative complications were noted.

Conclusion: Internal refixation with a girth-hitch suture is a relatively quick and convenient method for the management of a dislocated IOL haptic on one side.

修复巩膜固定式人工晶体单触点脱位的改良腰带钩缝合技术。

目的：描述一侧经巩膜固定的改良环扣缝合技术，以挽救单个触点脱位：在该手术技术报告中，使用 10-0 聚丙烯缝线环绕 IOL 触点，将脱位的巩膜固定后房 IOL 固定在巩膜上。本研究固定了三种类型的人工晶体（4 例 1 片式 PMMA 人工晶体、1 例带 PMMA 环的 3 片式丙烯酸人工晶体和 1 例带双板环设计的丙烯酸折叠式人工晶体）：结果：6 名因单结开裂导致巩膜固定的后房型人工晶体移位的患者采用该技术接受了巩膜固定人工晶体复位手术。所有病例都成功实现了人工晶体的重新定位和稳定的中心固定。术中和术后均未发现并发症：结论：使用环状缝合线进行内固定是处理一侧人工晶体触点脱位的相对快捷方便的方法。
