In vivo characterization of morphologic changes in the lens during accommodation as a function of age by use of OCT with swept-source technology.
Observational study in Japanese journal of ophthalmology, 2025. 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
purposeTo characterize the in vivo morphologic and biometric changes in the lens during accommodation as a function of age by use of swept-source OCT technology STUDY
designObservational, prospective study
methodsComplete optometric and ophthalmologic examinations were performed on all the patients to determine their eligibility for inclusion in the study. The examinations included anterior segment measurements obtained using swept-source OCT. Morphologic parameters of the lens were analysed under accommodative stimuli of 0, -1, -2, -3, and -6 D. A second measurement was taken 10 minutes after the first.
resultsThree hundred eyes of 300 patients were enrolled in the study. Structural changes in the lens were observed, specifically in the anterior and posterior radii, which decreased with accommodation, and the total thickness of the lens, which increased. In patients aged younger than 40 years, significant changes were found in the curvature radius and lens thickness during accommodation. In patients aged older than 40 years, these changes began to diminish. Significant differences between stimuli (P <.05) were observed in all the groups, demonstrating lens variation during accommodation and its dependence on age. Repeatability analysis showed an intraclass correlation coefficient of >0.700 for all the parameters.
conclusionsDuring accommodation, the anterior and posterior curvatures of the lens decrease, while its thickness increases. Age-related differences remained significant, indicating persistent changes over time. Swept-source OCT demonstrated high repeatability, particularly for anterior curvature, thickness, and tilt, even under accommodation.
