Purpose: The aim of this study was to assess the final visual outcome and various complications, encountered in the posterior iris-claw intraocular lens (IOL) implantation in aphakic eyes with inadequate capsular support. Methodology: Prospective case series of 30 eyes of 29 patients who underwent posterior iris-claw intraocular lens implantation in a tertiary care center within 1 year (January 2016 to June 2017) with a follow-up period of 6 months. All patients with visually significant posterior segment problems were excluded from the study. Main outcome measures were visual acuity, anterior chamber reaction, corneal edema, the stability of IOL, and cystoid macular edema (CME) at 6 months. Results: Of the 30 eyes enrolled in the study, 24 (86.7%) eyes were taken for elective secondary implantation. Four (13.3%) eyes were for primary iris-claw implantation, where subluxated or dislocated lens was noticed preoperatively. The indications for posterior iris-claw IOL in our study were surgical aphakia (24/30), traumatic subluxation of the cataractous lens (2/30), dislocated lens (2/30), and decentered posterior chamber IOL (2/30). Postoperative mean best-corrected visual acuity (BCVA) was LogMAR 0.3. Analysis of complications showed that the most common postoperative complications were iritis (36%), corneal edema (30%), striate keratitis (26.6%), hyphema (6.66%), iris capture (6.66%), and CME (3.33%). Conclusion: Surgical aphakia is the most common indication for posterior iris-claw IOL implantation. Postoperative mean BCVA is comparable with other methods. Iritis is the most common complication. This technique is a relatively safe and easy procedure learned by postgraduate students.
