Knot-free suture scleral fixation of dislocated intraocular lenses: clinical results of a novel surgical technique

Abstract

Purpose: To describe and report surgical outcomes of a novel, knot-free technique to manage dislocated intraocular lenses (IOLs). Setting: Beyoglu Eye Education and Research Hospital, Istanbul, Turkey. Design: Retrospective observational clinical study. Methods: The files of 47 patients were retrospectively reviewed, and the patients who had a follow-up time of 6 months or more were included in this study. The surgery of every case was watched for the surgical complications and calculation of the surgical time. The postoperative complications and success rate were specifically tabulated. Results: Thirty-five eyes of 35 patients were included in this study (23 men, 12 women; mean age 63.1 +/- 19.2 years). The mean followup time was 22.5 +/- 9.9 months. The mean surgical time was 28.2 +/- 6.8 minutes. Corrected distance visual acuity improved significantly after surgery (P = .001). Anatomic success rate was 97.1% after a single surgery. Most common complications included transient intraocular pressure (IOP) elevation (n = 2), persistent IOP elevation (n = 1), mild IOL tilt (n = 1), mild IOL decentration (n = 1), secondary IOL dislocation requiring intervention (n = 1), transient corneal edema (n = 1), and bullous keratopathy (n = 1). Discussion: Knot-free suture scleral fixation of dislocated IOLs was a minimally invasive approach for the management of dislocated IOLs and required only two 20-gauge corneal incisions without the need for scleral flaps or incisions. This technique had a low complication rate and delivered successful results in most cases. Copyright (C) 2021 Published by Wolters Kluwer on behalf of ASCRS and ESCRS
