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.
