Individuals with less than 3 months of follow-up, chronic uveitis, congenital cataract, previtrectomy retinal detachment (RD), and severe trauma were excluded. All analyses for categorical and binary variables used chi-squared tests. Analyses for continuous variables were performed using multivariate analyses of covariance, adjusting for differences in baseline visual acuity before cataract surgery.Results: The study included 246 eyes of 246 patients. The timing distribution included the following: 140 (57%) eyes underwent same-day PPV, 33 (13%) eyes underwent same-week PPV, and 73 (30%) eyes underwent PPV after 1 week (up to 90 days). When all eyes were included in analysis, there were no statistically significant differences in mean best-corrected visual acuity (BCVA) between groups at last follow-up examination (P = 0.07). When only eyes without known pre-existing ocular disease (N = 157) were included in analysis, there were no differences in mean BCVA between groups at all postoperative timepoints (P > 0.05). The rate of RD did not differ between groups when eyes with and without pre-existing ocular disease were analyzed (P > 0.05).Conclusion: In the current study, there were no statistically significant differences in postoperative BCVA or rates of RD at last follow-up examination in eyes undergoing PPV for RLF on the same day, within 1 week, or later than 1 week after cataract surgery.Keywords: retained lens fragments, pars plana vitrectomy, cataract surgery, retinal detachment
