Visual Quality and Accommodation With Novel Optical Designs for Myopia Control.
Article in Translational vision science & technology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Purpose: We evaluated through-focus visual performance and accommodative response in young subjects through three segmented multifocal designs for myopia control, mapped on the spatial light modulator of a monocular adaptive optics visual simulator (AOVS), and compared with single vision (SV). Methods: The segmented multifocal patterns included a 4 mm diameter center distance zone and offset peripheral defocus (MP1), astigmatism and coma (MP2), or a combination (MP3). High-contrast logMAR visual acuity (VA) was measured with monochromatic stimuli (555 nm). Ocular aberrations were measured using the Hartmann-Shack aberrometry channel. Measurements were taken for distance viewing and five accommodative demands (AD, up to 4.5 D). Accommodative lag was calculated from the dioptric shift of the maximum retinal image quality metric from the corresponding wave aberrations. Results: Best-corrected logMAR VA was -0.11 ± 0.02 (SV) and slightly reduced by multifocal patterns (-0.08 ± 0.03 [MP1], -0.07 ± 0.04 [MP2], -0.05 ± 0.04 [MP3]). Accommodative lag with SV was lower in emmetropes than myopes (by 0.43D for the largest demand). MP1 significantly decreased accommodative lag in myopes (P = 0.03), unlike MP2 or MP3. Multifocal patterns reduced pupil diameter in myopes at all distances. MP1 improved accommodative response in myopes without compromising distance vision. Conclusions: AOVS helped to understand the interplay of physiological and lens design factors, potentially guiding custom corrections. A center distance with off-centered positive power in the lens periphery could feature suitable properties (peripheral focus and accommodative focus control) for myopia control. Translational Relevance: We demonstrate a two-zone contact lens design that provides excellent visual quality and accommodative response, important properties for myopia control lenses.
