Surgical and refractive outcomes of a novel modified sclera-fixated Rayner intraocular lens utilizing Gore-tex suture.

Abstract

To evaluate the surgical outcomes of a novel modified scleral-fixated Rayner intraocular lens (IOL) with Gore-Tex suture. Retrospective chart review was conducted who had sclera fixation Rayner IOL and pars plana vitrectomy utilizing Gore-Tex suture without scleral flap between November 2021 and June 2024. Data included best corrected visual acuity (BCVA), spherical equivalent (SE), and complications. Difference between postoperative SE and preoperative predicted refraction are calculated as prediction error (PE). 103 patients (103 eyes) with mean age of 64.7 ± 13.0 years are included. 73 patients are male, and BCVA improved from logMAR 1.12 ± 0.66 (20/263 Snellen) to 0.50 ± 0.56 (20/63 Snellen) (p < 0.001). Mean postoperative SE was -1.32 ± 1.49 D, and mean PE was -0.81 ± 1.16 D. Refractive outcomes showed 76.7% of patients were within ±1.5 D and 92.2% were within ±2.5 D of the refractive target. Postoperative complications included transient elevated intraocular pressure (7.77%), transient hypotony (1.94%), cystoid macular edema (6.80%), vitreous hemorrhage (1.94%), stitch exposure (2.91%), and IOL tilt or subluxation (2.91%). The novel modified scleral fixation technique was safe with transient and tolerable complications. The study observed an average myopic shift 0.81 D in refractive outcomes.
