COMPARISION OF SUTURED VERSUS SUTURELESS SCLERAL FIXATED INTRAOCUALR LENS AT A TERTIARY EYE HOSPITAL, NEPAL

Abstract

Background: One of the best options for correction of aphakia is scleral fixated intraocular lens. It can be implanted either using suture or without the use of suture. Each technique has its own pros and cons. The aim of this study was to compare the visual outcome and complications between the suture and sutureless technique of scleral fixation intra ocular lens.

Methods: It was a retrospective study done at a tertiary eye hospital in Koshi Province, Nepal where data of patients who underwent scleral fixated intraocular lens implantation from March 2017 to June 2017 were analyzed. Aphakic patients with absence of capsular support, subluxated lens (>180˚) and patients with posteriorly dislocated IOL with minimum follow up of 6 months were included in the study. All the data were entered into the SPSS version 20, descriptive analysis was done and independent t-test was applied to test the statistical significance.

Results: Sixty-six eyes of 66 patients were included in the study. Out of which 51.5% underwent sutured and 48.5% underwent sutureless scleral fixated intraocular lens implantation. Male: female ratio was 1.6:1. Most common indication for scleral fixated intraocular lens was traumatic dislocation of lens. Mean postoperative vision of sutured and sutureless SFIOL when compared, sutured SFIOL was found to have statistically significant improvement. Most common complication was corneal edema in both the groups.

Conclusions: Both techniques of scleral fixated intraocular lens showed satisfactory improvement in vision, but sutured SFIOL showed better vision postoperatively.
