To report the clinical outcomes and complications in eyes with subluxated intraocular lens (IOL) repositioned with a looped 10.0 polypropylene suture.
Retrospective study, Retina Ophthalmic Research Center , Izmir
Nineteen eyes of 19 (12 male, 7 female) patients with subluxated IOL underwent repositioning with a looped 10.0 polypropylene suture from 2009 to 2020 were included in this retrospective study. Looped 10.0 polypropylene suture was suspended the haptic or passed through the haptic root of the IOL and fixed to sclera. Surgical approach was performed depending on position and type of IOLs with minimal manipulation and intraocular complication risk. Preoperative and postoperative (po) best corrected visual acuity (BCVA), spherical equivalent (SE), refractive astigmatism (RA), intraocular pressure (IOP), location of subluxation, etiology and po complications were analyzed.
Mean age of patients was 73.6±9 years. Mean duration from cataract surgery to subluxation was 77.6±51.5(8-156) months. Mean follow-up was 61.2±54.1(6-152) months. Four(21.1%) patients had pseudoexfoliation, 3(15.3%) history of yag laser capsulotomy, two(10.5%) myopia, five (26.3%) atopic conjunctivitis, 1(5.3%) trauma, 2(10%) history of vitreoretinal surgery. Subluxation of IOL was located mostly inferiorly (57%). Mean BCVA was improved from 0.89±0.9(0.05-3.10)logMAR to 0.43±0.4(0-1)logMAR (p=0.03). Mean po SE was -0.50±1.4 D and RA was 1.04±1.2D. Seven patients had high IOP.Mild IOL dislocation and corneal edema was seen in two patients whereas cystoid macular edema was observed in one patient.
Long term outcomes of repositioning of subluxated IOL with looped 10.0 polypropylene suture revealed that this surgical technique is an easy, safe and effective surgical option for such cases.
