Normative Values on Stromal Curvature, Power and Corneal-Stromal Curvature Ratios From a Hybrid AS-OCT.
Observational study in Clinical & experimental ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundTo establish normative values for stromal curvature and its relationships to anterior and posterior curvature.
methodsRetrospective observational study. Data were obtained from 75 eyes of cataract surgery patients using a high-resolution anterior segment optical coherence tomograph (AS-OCT; MS-39, CSO). Data analysis included anterior, stromal, and posterior curvature across multiple zones (1.0-5.0 mm), and derived curvature ratios.
resultsThe anterior-to-stromal curvature ratio (ASR) remained stable (1.016-1.007), while the stromal-to-posterior (SPR) and anterior-to-posterior (APR) ratios exhibited trends of slight change (SPR: 1.149-1.167; APR: 1.167-1.175). The refractive power analysis revealed incremental effects across one, two, and three refractive surface models, emphasising the importance of integrating posterior and stromal curvature data into optical assessments.
conclusionThis study provides the first normative values for stromal curvature and its ratios with anterior and posterior curvature. These findings may have implications for corneal- and lens-based surgeries and diagnostics.
