Intraoperative complications of phacoemulsification in pseudoexfoliation: Metaanalysis.

This review analyzed the effect of pseudoexfoliation (PXF) syndrome on the risk for surgical complications during phacoemulsification. Peer-reviewed literature in Medline, Embase, Lilacs, Web of Science, and Cochrane databases was systematically searched, along with gray literature in the Teseo and National Institutes of Health clinical trials database. Clinical trial, cohort, case-control, and cross-sectional studies comparing phacoemulsification complications in patients with and without PXF were identified, and 22 of 30 studies were selected for analysis. Odds ratios (ORs) for posterior capsule rupture or zonular dialysis were calculated and pooled using random-effects models. A random-effects meta-regression model was also generated. Using the random-effects model, the pooled OR was 2.1363 (95% confidence interval, 1.5394-2.9648), which corresponds to a risk of more than 10%. No significant changes to this risk were observed in the cumulative or stratified analyses. Although advances in surgical technique have been made, PXF syndrome continues to be a risk factor in phacoemulsification.
