Predictive factors and visual outcomes after immediate pars plana vitrectomy for posteriorly dislocated lens fragments during complicated phacoemulsification surgery

Abstract

Purpose: To investigate the prognostic factors for visual outcome in patients undergoing immediate pars plana vitrectomy (PPV) for posteriorly dislocated lens fragments during phacoemulsification surgery. Methods: This was a single-center, retrospective, cross-sectional study of 37 eyes of 37 patients undergoing immediate PPV for posteriorly dislocated lens fragments from 2015 to 2021. The primary outcome measure was changes in the best-corrected visual acuity (BCVA). Additionally, we analyzed the predictive factors for poor visual outcomes (BCVA 50% of lens matter into the vitreous (P 50%), use of an iris-claw lens, and CME.
