Long-Term Visual Outcome and Clinical Predictors Following Yamane Sutureless Intrascleral IOL Fixation

Sutureless intrascleral intraocular lens fixation using the Yamane technique is an established option for visual rehabilitation in eyes without capsular support. This study evaluated long-term visual outcomes and predictors of postoperative best-corrected visual acuity (BCVA) following Yamane SFIOL implantation. In this single-center, single-surgeon consecutive case series, patients undergoing surgery for aphakia or lens/posterior chamber intraocular lens ectopia with ≥12 months of follow-up were included. BCVA was measured using a standard Snellen chart and recorded in decimal notation. Univariable screening followed by clinically driven multivariable linear mixed-effect regression was performed. Eighty-seven eyes of 85 patients were analyzed (mean age 68.2 ± 11.4 years; 70.6% male). Median BCVA improved significantly from 0.2 preoperatively to 0.9 postoperatively (p < 0.001), with a median follow-up of 26.5 months. Surgical indication was not associated with postoperative BCVA (B = −0.015, p = 0.752), nor was preoperative comorbidity burden. In multivariable analysis, older age (B = −0.005, p = 0.027), macular edema (B = −0.242, p = 0.035), and prior silicone oil removal (B = −0.237, p = 0.046) were independently associated with lower postoperative BCVA. Yamane SFIOL provides significant long-term visual improvement, while postoperative visual outcomes are primarily determined by age and retinal status.
