Effect of prior intravitreal injections on the risk of posterior capsule rupture during cataract surgery: a single-surgeon matched case-control study.
Article in BMC ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeTo evaluate the impact of a history of intravitreal injections (IVI) for various retinal diseases on the risk of posterior capsule rupture (PCR) during cataract surgery in a single-surgeon setting. MATERIALS AND
methodsThis retrospective, matched case-control study included 93 eyes of 74 patients who underwent phacoemulsification after prior IVI (anti-VEGF and/or dexamethasone) and 93 control eyes without prior IVI, matched for age, gender, laterality and axial length. All surgeries were performed by the same experienced surgeon. The primary outcome was the incidence of PCR. Statistical analyses was performed using Chi-square tests and logistic regression.
resultsAll eyes in the IVI group had received at least two injections (mean: 5.71 ± 3.5). PCR occurred in 3 eyes (3.2%) in both the IVI and control groups (p = 1.00). There was no statistically significant difference in overall intraoperative complication rates between the two groups (8.6% vs. 7.5%, p = 0.79). Logistic regression analysis revealed no significant association between PCR and the number of injections, injection agent (anti-VEGF or dexamethasone), time from first injection to surgery, or retinal disease subtype (p > 0.05 for all).
conclusionIn this study, a history of IVI was not associated with an increased risk of PCR or other intraoperative complications during cataract surgery. These findings suggest that cataract surgery following IVI can be safely performed by an experienced surgeon without an increased risk of PCR.
