Aim: This study aims to evaluate the safety, effectiveness, and complications of posterior iris-claw intraocular lens (IOL) in aphakic patients with inadequate capsular support. Patients and Methods: This prospective interventional study was conducted in 100 eyes of 99 patients between July 2013 and June 2017. Surgical aphakia with inadequate capsular support, large zonular dialysis, subluxated lens, dislocated lens, dislocated IOL, and aphakia following congenital cataract surgery were included. Preoperative and postoperative best-corrected visual acuity (BCVA) and the occurrence of various vision-threatening complications such as iridocyclitis, decentration, vitritis, cystoid macular edema, and retinal detachment were considered during the follow-up period. Results: One hundred eyes of 99 patients who fulfilled the criteria were included. The mean follow-up period was 13.5 months (4–24 months). About 90% of patients had improvement in vision with postoperative BCVA of 6/12–6/6, 7% had visual improvement with postoperative BCVA of 6/18–6/36, and 3% had a drop in visual acuity with BCVA < 6/60. About 15% developed iridocyclitis in the immediate postoperative period and responded well to topical steroids. Nearly 2% developed vitritis during the follow-up period and 1% developed rhegmatogenous retinal detachment. None had decentration or cystoid macular edema during the follow-up period. Conclusion: Posterior iris-claw IOL implantation is a safe, effective, and timely procedure in aphakia with inadequate capsular support in the hands of a skilled experienced surgeon.
