Risk factors for postoperative endothelial keratoplasty after cataract surgery in patients with Fuchs endothelial corneal dystrophy using anterior segment optical coherence tomography.
Observational study in Japanese journal of 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 analyze anterior segment optical coherence tomography (AS-OCT)-derived risk factors for endothelial keratoplasty (EK) after cataract surgery in patients with Fuchs endothelial corneal dystrophy (FECD). STUDY
designRetrospective observational study.
methodsWe included 73 eyes from 55 consecutive patients with FECD who underwent cataract surgery at three tertiary care institutions between March 2017 and July 2023. We explored the association between preoperative factors (age, sex, incision site, central corneal thickness, anterior chamber depth, components for the anterior and posterior corneal surfaces by Fourier analysis, and signal intensity by AS-OCT) and the requirement for EK within 12 months after cataract surgery. We performed univariate and multivariate regression analyses to calculate the area under the receiver operating characteristic curve (AUC).
resultsOf the 73 eyes, 27 (37.0%) required EK. In the univariate analysis, the higher order irregularity component of the 6 mm posterior corneal surface by Fourier analysis yielded the highest AUC of 0.86 (sensitivity: 0.85; specificity: 0.74). In the multivariate analysis, the asymmetry component of the 3 mm anterior corneal surface by Fourier analysis yielded the highest AUC of 0.94, in addition to age, sex, incision site, and anterior chamber depth (sensitivity: 0.93; specificity: 0.85). Thus, we developed a novel logistic regression model incorporating fully quantitative imaging biomarkers from AS-OCT to estimate the probability of requiring EK.
conclusionThe multiple regression model might provide a practical framework for optimizing surgical planning in patients with FECD undergoing cataract surgery, including deciding for either cataract surgery alone or combined EK.
