Purpose: To describe a modified scleral fixation technique for a 4-haptic foldable intraocular lens (IOL) 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 9 eyes of 9 patients, who underwent modified scleral fixation of a 4-haptic foldable IOL between January 2023 and January 2024. Results: Over a mean follow-up period of 10.89 months, postoperative LogMAR best-corrected visual acuity (BCVA) improved significantly (20/43 vs. 20/130 preoperatively). The mean IOL tilt was 0.27 ± 0.09 µm, with acceptable endothelial cell loss (9.96%). No intraoperative or postoperative complications were observed. Conclusion: This technique performed through a small incision, achieves reliable IOL positioning and visual improvement via four-point fixation while effectively eliminating suture-related complications.
