LONG-TERM OUTCOMES OF SUTURELESS INTRASCLERAL INTRAOCULAR LENS FIXATION IN CHILDREN AND ADULTS: Single-Surgeon Case Series With and Without Haptic Flanging With Up to 11 Years of Follow-Up.

Abstract

Report and compare long-term outcomes and complications of sutureless scleral tunnel (SST) and flanged haptic (FH) scleral-fixated intraocular lens, with spontaneous intraocular lens (IOL) dislocation as primary outcome measure. Retrospective single-surgeon case series of 95 SST and 458 FH eyes from 2011 to 2022 (553 total eyes). Demographics, surgical indications, ocular history, visual acuity, and complication rates were collected. Reoperation-requiring spontaneous IOL dislocation rate was significantly different ( P = 0.0167) between FH (3.7%) and SST (10.5%). Mean follow-up was 3.31 ± 0.30 versus 1.58 ± 0.07 years for SST and FH, respectively. There was no significant difference between preoperative (20/305 vs. 20/300) or final postoperative (20/77 vs. 20/62) visual acuity. Other complications included any cystoid macular edema (20.0% vs. 25.3%), elevated intraocular pressure (16.8% vs. 9.6%), IOL tilt requiring reoperation (5.3 vs. 0%), haptic exposure (2.1% vs. 3.3%), and reverse pupillary block (4.2% vs. 1.1%). Haptic flanging resulted in fewer eyes meeting the primary end point of IOL dislocation. We reported the longest-to-date follow-up of both nonflanged SST IOL fixation and our FH-modified Yamane technique. Our FH-modified Yamane technique represents a safe, durable, and potentially superior option for scleral-fixated intraocular lens.
