Retrospective analysis of visual outcomes in retropupillary iris-suture-fixated rigid intraocular lens in a tertiary eye center in southern India.

Abstract

To report clinical outcomes of retropupillary iris-suture-fixated rigid intraocular lens (IFIOL) SETTING: Tertiary care ophthalmic hospital DESIGN: Retrospective study METHODS: This study included all eyes undergoing IFIOL with a minimum follow-up of 6months between April 2017 and January 2019. Patients with preexisting anterior or posterior segment pathologies causing defective vision, uveitis or history of previous intraocular surgeries with exception of cataract surgery were excluded from the study. Data were retrieved from electronic medical records, and we documented demographics, history, position of cataractous lens or IOL, primary/secondary surgery and its complications. Postoperative visual acuity, pupillary response, diplopia, centration of IOL, inflammation were also recorded at the baseline visit and at 1month, 3months and 6months postoperatively. One hundred and ten eyes of 110 patients that underwent IFIOL were evaluated. Twenty-two patients (20%) underwent primary IFIOL, whereas 67 (60.9%) patients had secondary IFIOL. In 18 patients (16.36%), IFIOL was done to reposition decentered/dislocated IOLs. At the final follow-up, there was a significant improvement in corrected distance visual acuity (CDVA) with 87 patients (79.09%) achieving CDVA of 6/12 or better. IFIOL was stable and centered in 101 eyes (91.81%). Two patients (1.81%) had intraoperative complications. Postoperative iritis was seen in 7 patients (6.36%), and 4 patients (3.63%) had rise in IOP. This is a safe, reliable, reproducible technique for aphakia rehabilitation and decentered IOL stabilization with good clinical outcome, especially in a limited resource setting.
