Clinical Outcomes Of Retropupillary Iris Suture Fixated Rigid Intraocular Lens

To report clinical outcomes of retro-pupillary iris suture fixated rigid intraocular lens (IFIOL) for eyes with compromised capsular bag support and to stabilize decentered IOLs

Tertiary care ophthalmic hospital

This study included all eyes undergoing IFIOL with a minimum follow-up of 6 months between April 2019 and January 2021. Patients with pre-existing 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. Post-operative visual acuity, pupillary response, diplopia, centeration of IOL and inflammation were recorded at the baseline visit and at 1 month, 3 months and 6 months 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 intra-operative complications. Post-operative iritis was seen in 7 patients (6.36%) and 4 patients (3.63%) had IOP rise.

This is a safe, reliable and reproducible technique for aphakia rehabilitation and decentered IOL stabilisation with good clinical outcome, especially in a limited resource setting.
