Abstract

Purpose: To describe a modified scleral fixation technique for a four-haptic foldable intraocular lens using 10-0 looped polypropylene sutures, aimed at reducing suture exposure risks and enhancing centration stability in eyes with inadequate capsular support.

Methods: This retrospective interventional study included nine eyes of nine patients, who underwent modified scleral fixation of a four-haptic foldable intraocular lens between January 2023 and January 2024.

Results: Over a mean follow-up period of 10.89 months, postoperative logarithm of the minimum angle of resolution best-corrected visual acuity improved significantly (20/43 vs. 20/130 preoperatively). The mean intraocular lens tilt was 0.27 ± 0.09 µ m, with acceptable endothelial cell loss (9.96%). No intraoperative or postoperative complications were observed.

Conclusion: This technique performed through a small incision, achieves reliable intraocular lens positioning and visual improvement via four-point fixation while effectively eliminating suture-related complications.

环形缝合线辅助巩膜固定4环触觉人工晶状体。

目的：描述一种改良的巩膜固定技术用于使用10-0环聚丙烯缝合线进行4触觉可折叠人工晶状体（IOL），旨在减少缝合线暴露的风险，提高眼膜支持不足的眼睛的集中稳定性。方法：回顾性介入研究包括2023年1月至2024年1月期间接受改良巩膜固定4触觉可折叠IOL的9例患者的9只眼。结果：平均随访10.89个月，术后LogMAR最佳矫正视力（BCVA）明显改善（20/43 vs.术前20/130）。平均IOL倾斜0.27±0.09µm，内皮细胞损失（9.96%）可接受。术中、术后均无并发症。结论：该技术通过小切口进行，通过四点固定实现可靠的IOL定位和视力改善，同时有效地消除了缝合线相关并发症。
