Posterior Capsule Rupture and Vitreous Loss in Cataract Surgery: A Retrospective Analysis from a Swiss Tertiary Center.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To determine the incidence of posterior capsule rupture (PCR) and vitreous loss (VL) during cataract surgery in a Swiss tertiary care center. Furthermore, we aimed to evaluate preoperative risk factors associated with PCR/VL, including pseudoexfoliation (PEX), age, type of anesthesia, and the Triemli Cataract Score (TCS), a locally implemented preoperative risk assessment tool for surgical complexity. Methods: This retrospective single-center cohort study included all phacoemulsification and refractive lens exchange procedures performed at Stadtspital Zürich between January 2021 and late August 2024. Data were retrieved from the Dendrite clinical database of the TCS and supplemented through manual chart review and surgical reports for identification of intraoperative complications. Univariable and multivariable logistic regression analyses were performed to evaluate associations between preoperative factors and the occurrence of PCR and/or VL. Results: A total of 2'719 eyes were included in the study. PCR and/or VL occurred in 52 eyes (1.9%), including 45 cases of PCR (5 with concomitant VL) and 7 additional cases of isolated VL due to zonulolysis. In univariate analysis, PEX and a TCS ≥3 were significantly associated with an increased risk of PCR and/or VL (OR 2.72; p=0.003 and OR 2.38; p=0.002, respectively), while topical (vs. general) anesthesia was associated with a reduced risk (OR 0.51, p=0.019). In multivariate analysis, only PEX remained an independent risk factor (OR 2.38; p=0.013). The association between TCS ≥3 and PCR/VL just missed statistical significance (OR 1.79; p=0.057). Conclusion: The rate of PCR and/or VL during cataract surgery at a Swiss tertiary care center is comparable to international statistics. PEX is a strong and independent predictor for these complications; although the predictive power of TCS did not reach statistical significance in multivariable analysis, the observed trend suggests that risk-based preoperative scores such as the TCS may support risk-stratification and surgical planning in clinical practice.
