Secondary Scleral Fixated Intraocular Lens Implantation in Aphakia – Sutured vs Sutureless SFIOL’s

Abstract

Purpose: To study and compare the safety and efficacy of two techniques of SFIOL implantation, i.e. sutured versus sutureless SFIOL. Methods: 80 aphakic eyes (due to complicated cataract surgeries in the past) were included in our study. Secondary SFIOL implantation was done in all the subjects. Patients were randomly divided into 2 groups using lottery method. Preoperative BCVA, slit lamp examination, fundus examination, macular OCT and IOP were noted for both the groups. In both the groups, SFIOL was implanted after doing anterior vitrectomy. Group A consisted of 40 patients who underwent SFIOL implantation (sutured) using 9-0 prolene suture whereas Group B consisted of 40 patients who underwent SFIOL implantation using Modified Yamane technique (sutureless). Results: Pre-operative BCVA of 26 patients (65%) in Group A and 22 patients (55%) in Group B was found to be less than 3/60. Post-operative BCVA at 6 months follow up was found to be in range of 6/24 to 6/18 in 28 patients (70%) in  Group A and 24 patients(60%) in Group B. We found that the postoperative visual acuity improved in both the groups as compared to preoperative levels but comparison of post operative BCVA between the two groups was not significant. Conclusion: Results of both the techniques are comparable. Long-term data comparing the various techniques used to place SFIOLs will be crucial to identify optimal strategies for SFIOL implantation.
