Clinical outcome of iris-claw intraocular lens implantation

Abstract

Aim: The aim of this study is to study the indications, visual outcome, and complications in patients undergoing iris-claw intraocular lens (IOL) implantation. Settings and Design: This is a prospective interventional case series conducted between January 2016 and June 2017 in a tertiary care hospital. Materials and Methods: Seventy-nine eyes of 78 patients with aphakia or subluxation of lens of various etiologies were included in the study. Complete ophthalmological examination was conducted. Retropupillary iris-claw IOL implantation was done in the included patients. Patients were followed-up to 6 months for visual acuity, intraocular pressure measurement, and complications. Statistical Analysis Used: Statistical analysis was performed by the Students t-test. Results: The difference between preoperative and postoperative visual acuity was statistically significant in the group of patients undergoing iris-claw IOL implantation as a primary procedure (P < 0.0001). The difference was insignificant in the aphakic patients undergoing secondary IOL implantation. The interval between the primary surgery and the secondary procedure did not make a statistically significant impact on the visual outcome (P = 0.67). Common complications after iris-claw IOL implantation in this study noted were corneal edema, pupil ovalization, raised intraocular pressure, and iris atrophy. Conclusions: Retropupillary iris-claw IOL implantation is a safe and easy method of managing patients with aphakia and subluxation of the lens.
