Comparative Functional and Morphological Data of Different IOL Dislocation Undo Methods

Background/Objectives: This study compared the results of iris-sutured, late spontaneously dis-located IOL-capsular bag complexes with IOL exchange using anterior chamber intraocular lenses (ACIOL) in a tertiary reference center in Lithuania. Methods: A prospective observational study was conducted between 2017 and 2019 involving 80 patients (83 eyes) with late spontaneous IOL-capsular bag dislocation. Patients underwent repositioning and fixation of the dislocated IOL to the iris (IF group) or IOL exchange with an ACIOL implant (ACIOL group). Pre- and postoperative assessments included best-corrected distance visual acuity (BCDVA), intraocular pressure (IOP), corneal endothelial cell density (ECD), and macular thickness (evaluating whether cystoid macular edema (CME) has occurred). Results: Both groups showed a significant improvement in BCDVA, with a more remarkable improvement in the IF group (median: 0.1 logMAR) than in the ACIOL group (median: 0.3 logMAR), p=0.001. Corneal astigmatism increased significantly in the ACIOL group (p
