Surface and Antifouling Properties of a Biomimetic Reusable Contact Lens Material.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 comprehensive in vitro and ex vivo study was conducted for a newly developed biomimetic silicone hydrogel contact lens material, lehfilcon A, with poly-(2-methacryloyloxyethyl phosphorylcholine) (PMPC) surface modification. In vitro studies, including Sudan Black staining and fluorescence imaging, were executed to assess the surface wettability and lipid deposition of contact lenses after simulated prolonged exposure. Additionally, the lens surface softness and lubricity were characterized by ex vivo studies, including atomic force microscopy and tribological testing. The PMPC-modified surface stayed hydrophilic and resisted lipid accumulation during the simulated wearing cycles. The coefficient of friction and surface modulus were maintained, even after 30 days of patient use. These findings demonstrate that the PMPC-modified material offers exceptional surface properties and antifouling performance, presenting an advancement in biomimetic contact lens technology.
