Video-based evaluation of cataract surgery and intraoperative complications: a single surgeon's 12-year experience.
Article in International 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 intraoperative complications of cataract surgeries, identify their independent risk factors, and determine how complication rates evolve over time by reviewing surgical videos, considering both the surgeon's experience and baseline patient characteristics.
methodsThis retrospective, cross-sectional study evaluated 523 high-quality cataract surgery videos (selected from 1770) performed by a single surgeon with over five years of baseline experience. Videos were divided into group 1 (2010-2017, n = 274) and group 2 (2018-2022, n = 249). Patient cooperation, intraoperative complications, and specific preceding surgical steps were analyzed via video. Cataract grading and pupil diameter were obtained from patient files and video recordings. Univariate and multivariate logistic regression analyses were performed.
resultsUnivariate analysis showed complication rates (p = 0.026), cataract hardness (p = 0.002), and accompanying ocular findings (p = 0.009) were significantly higher in group 1. Patient cooperation was significantly lower in eyes with complications in group 1 (p = 0.003). Multivariate regression analysis revealed that only poor patient cooperation (OR = 4.862, 95% CI 741-13.579, p = 0.003) and higher nucleus grade (OR = 5.510, 95% CI 1.258-24.134, p = 0.024) were significant independent predictors of intraoperative complications.
conclusionPatient cooperation and cataract hardness are the primary independent predictors of surgical safety. It is crucial that high-risk cases are carefully pre-assessed and operated on by experienced surgeons equipped with advanced crisis management strategies. High-quality surgical video recordings provide analytically indispensable insights, proving highly beneficial for both postoperative case review and the training of resident physicians.
