PURPOSE
To describe a repositioning technique of a subluxated scleral-fixated rigid intraocular lens (IOL) with haptic holes in eyes with complete or anterior vitrectomy.
DESIGN
Interventional case series.
METHODS
Using a two-port pars plana vitrectomy, a 10-0 polypropylene suture with the free end fixated to a haptic hole cut from another artificial IOL is passed through a paracentesis, then through the hole of the haptic luxated in the vitreous cavity. It is then reanchored at the sclera, repositioning the IOL.
RESULTS
In the two eyes, visual acuity was restored to pre-subluxation levels. During 6-month follow-up, anatomic and functional results were stable, and there were no complications.
CONCLUSIONS
This technique enables repositioning of a subluxated, previously sutured rigid IOL without externalization of the lens or haptics and with good results.
目的
描述一种在已行完全玻璃体切除术或前部玻璃体切除术的眼中，对带有襻孔的半脱位巩膜固定硬性人工晶状体（IOL）进行复位的技术。
设计
介入性病例系列。
方法
采用两通道经平坦部玻璃体切除术，将一根10-0聚丙烯缝线的游离端固定于从另一个人工晶状体上剪下的襻孔，经穿刺口穿过，然后穿过脱位至玻璃体腔的襻孔。随后将其重新固定于巩膜，使人工晶状体复位。
结果
在这两只眼中，视力恢复到半脱位前的水平。在6个月的随访期间，解剖和功能结果稳定，且无并发症。
结论
该技术能够在不使晶状体或襻外露的情况下，对先前已缝合的半脱位硬性人工晶状体进行复位，且效果良好。
