Comparative study between iris-claw and scleral-fixated intraocular lens in patients with aphakic eye

Abstract

AIM: To analyze the efficacy of iris-claw intraocular lens(ICIOL)and scleral-fixator intraocular lens(SFIOL)in terms of visual outcomes, surgical time, and postoperative complications in the aphakic patients.METHODS: This study was a prospective study with 60 aphakic eyes of 60 patients who attended our outpatient department from October 2018 to February 2020. These patients were divided into two groups and each with 30 patients. Patients in Group I were underwent ICIOL whereas patients in Group II underwent SFIOL implantation. Patients with pre-existing ocular pathologies, previous history of retinal surgery of the eye were excluded. The preoperative and postoperative evaluation was done for the follow up period of 9mo.RESULTS: Twenty-six(87%)patients in the ICIOL group and 24(80%)patients in SFIOL group had best corrected visual acuity(BCVA,LogMAR)with 0.50-0.00 after 9mo follow up. The mean of BCVA(LogMAR)was comparable in both the groups. The surgical time in ICIOL was significantly less than the SFIOL group(P<0.01). Complications related to sutures were significantly more in the SFIOL group. Complications found in the ICIOL group were very mild and harmless. CONCLUSION: The visual outcome was comparable in both groups. ICIOL with fewer complications and requiring less surgical time was found to be a better alternative to SFIOL in the correction of aphakia.
