Popis: Purpose: This study evaluated the long-term outcomes of managing posterior chamber intra-ocular lens (IOL) (PCIOL) subluxation through pars plana vitrectomy (PPV) with IOL iris suturing. Settings and Design: Retrospective chart review. Methods: Patients who underwent PPV with iris-sutured IOL (IS-IOL) for IOL subluxation between January 2008 and April 2021 at a tertiary center with a minimum of 6 months of follow-up were included. The patients were divided into two groups: those who had prior PPV and those who had not undergone the procedure. Results: A total of 54 patients underwent iris suturing of a subluxated IOL. Among them, 36 (66%) had previously undergone PPV, while 18 patients (33%) had not. The etiology of PCIOL subluxation was uncertain in 20 (37.0%), prior PPV in 17 (32%), and following complicated cataract surgery in 11 (20%) cases. The mean time between original IOL insertion and IS-IOL was 6.1 ± 7.0 years. The mean follow-up duration was 46.8 ± 39.7 months. The mean post-operative best corrected visual acuity (BCVA) was logMAR 0.43 ± 0.52 at final follow-up, a significant improvement from pre-operative BCVA. Vision was significantly better in the group with no prior PPV (logMAR 0.54 ± 0.59 vs. 0.21 ± 0.23 at final follow-up, P = 0.026). At final follow-up, 34 (63%) eyes had BCVA of 20/40 or better. The most common complication was cystoid macular edema, attributed to the IS-IOL in 13 (21.4%) eyes, 11 (68.6%) of which resolved or improved. Conclusions: The management of posterior chamber IOL subluxations with PPV and iris suturing of the subluxated IOL is a safe technique that provides excellent long-term visual outcomes.
