Agreement between swept-source OCT and Scheimpflug biometers in ocular measurements.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThis study evaluated the agreement of the ocular parameters obtained with the two optical biometers, the IOLMaster 700 and the Galilei G6 Lens Professional. PATIENTS AND
methodsA comparative prospective study was conducted on 159 eyes of 91 adult patients using the IOLMaster 700 and Galilei G6 devices by a single examiner. Agreement between ocular biometric parameters: white-to-white (WTW) distance, keratometry (flat (K1) and steep (K2), mean (Km)) of anterior, posterior, and total corneal surfaces, central corneal thickness (CCT), anterior chamber depth (ACD), and axial length (AL) were assessed using Bland-Altman analysis. Keratometry measurements were further transformed into power vector components J0 and J45 for astigmatism analysis. Clinically significant differences were defined as deviations in biometric parameters translating to differences of 0.25 D or more in refractive outcomes.
resultsStatistically and clinically significant difference was identified for ACD (mean difference: -0.15 mm), posterior corneal metrics: K1 (0.39 D), K2 (0.42 D), Km (0.41 D) and J0 (0.05 D) and total corneal metrics: K1 (0.95 D), K2 (0.91 D), Km (0.93 D) and J0 (0.13 D). No significant differences were found for J45 components of posterior and total K, WTW, CCT, and AL measurements.
conclusionThe difference in measurements of anterior chamber depth (ACD), posterior K, and total K metrics are clinically significant making the two devices are clinically significant and not interchangeable. These variation in metrics can impact the refractive outcomes of refractive and cataract surgery with toric IOLs.
