To describe a technique for suturing a dislocated intraocular lens (IOL) with 25-gauge (G) instruments.
Non-comparative interventional case series performed at a single center. Five patients with a dislocated IOL underwent 25-G transconjunctival sutureless vitrectomy (25G-TSV) with a temporary externalization of the haptics to fixate the IOL. Three IOLs enclosed in the lens capsule were dislocated into the vitreous and removed from the capsule with 25G-TSV using perfluorocarbon liquid. The best-corrected visual acuity and surgical complications resulting from this technique were recorded.
In all cases, the IOL was fixed stably and remained well positioned. The visual acuity was improved or maintained in all cases. There were no intraoperative or postoperative complications except for one eye with a postoperative iris capture of the sutured IOL.
Findings indicate that 25G-TSV is a practical and safe method for fixating a dislocated IOL.
描述一种使用25号（G）器械缝合脱位人工晶状体（IOL）的技术。
在单一中心进行的非对比性介入病例系列研究。5例IOL脱位患者接受了25G经结膜无缝合玻璃体切除术（25G - TSV），并临时将袢外置以固定IOL。3例包裹在晶状体囊袋内的IOL脱位至玻璃体腔，在25G - TSV中使用全氟碳液体将其从囊袋中取出。记录该技术导致的最佳矫正视力和手术并发症。
所有病例中，IOL均稳定固定且位置良好。所有病例的视力均得到改善或维持。除1只眼术后出现缝合IOL的虹膜嵌塞外，无术中或术后并发症。
研究结果表明，25G - TSV是固定脱位IOL的一种实用且安全的方法。
