Dynamic presbyopia correction in the macular field of view by using a liquid crystal lens.
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 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
A large aperture matrix of tunable liquid crystal lenses (MTLCL) is used for dynamic presbyopia correction. The special electrode design and driving method allow the activation of local lenses at arbitrary lateral positions of the MTLCL. First, the study of tunable wavefronts, which can be generated by such a device, is presented. Then, the image quality at different viewing angles and distances is quantified. A driving algorithm has also been developed to increase the speed of focusing. It is shown that this device may provide continuous focus tunability (from 0 to 2.5 diopters), react within 0.5 s, operate with relatively low voltages (<5 V), and enable diffraction-limited on-axis aberrations. Finally, the results of a comprehensive evaluation of its performance with human subjects are reported, comparing the visual acuity (VA) achieved by using the approach proposed in this project against the natural human VA for objects in the near field.
