Methods: Iris-sutured PC IOL operations performed at Giresun University Faculty of Medicine, Giresun Training and Research Hospital Ophthalmology Clinic between January 2017 and May 2023 were examined retrospectively. The study included thirty-six eyes from 32 patients who had foldable acrylic IOL implantation using peripheral iris-sutured due to aphakia in the absence of capsule support. We aimed to evaluate patients who could not place an IOL for any reason during cataract surgery, who underwent iris-sutured PC IOL surgery at least two months after cataract surgery, and who were followed up for at least one year.

Results: A total of 36 eyes of 32 patients were included. Mean overall follow-up was 9.5±3.56 months (range 6-54 months). There was an overall improvement in best-corrected visual acuity from mean preoperative logMAR 1.02±0,60 to postoperative logMAR 0,23±0,05. While the preoperative average astigmatic error was 1.72±0.55D, the postoperative average astigmatic error was 1.69±0.87D (p=0.512). Complications of intraocular surgery with iris fixation with sutures included transient low-grade uveitis (4 eyes [11%]), IOL dislocation (1 eye [3%]), retinal detachment (3 eyes [8%]), early cystoid macular edema (CME) (7 eyes [19%]), late CME (4 eyes [11%]), and bullous keratopathy (1 eye [3%]). Endophthalmitis was not observed in any patient.

Conclusion: In the absence of capsule support, small-incision peripheral iris-sutured of 3-piece acrylic foldable IOL appears to be an effective and safe technique. Keywords : Aphakia, Iris-sutured posterior chamber IOL, Absence of capsule support, Secondary IOL implantation
