Vignetting and peripheral double images with intraocular lenses.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Intraocular lenses (IOLs) are widely used, yet raytrace evaluations show that vignetting at very large angles limits the visual field of the focused image, though this is not specifically noticed by patients. A rare patient observation of peripheral double images in both eyes was modeled to demonstrate that a second image can be formed more peripherally by light missing the IOL, with simulated images illustrating the effect. Bothersome "dark shadows" that are reported by a small percentage of IOL patients, called negative dysphotopsia, have a similar cause, but are never reported as double images. The eyes had average dimensions, but the iris was thinner on the temporal side, with a nasally decentered pupil, and a distinct gap between the iris and the IOL, which all permit additional light to miss the IOL to create the second image.
