An annular corneal microneedle patch for minimally invasive ophthalmic drug delivery.
Article in Science advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Microneedles directly penetrating into the cornea inevitably cause pain, corneal structure damage, and reduced light transmittance. In this work, a minimally invasive annular microneedle (A-MN) patch was developed avoiding direct puncture into the central cornea for ophthalmic drug delivery. The feasible mechanical strength of A-MNs was achieved by adjusting the ratio of PVP-β-CD and PVA to puncture the cornea barrier. Through effective diffusion to corneal stroma, bioavailability of hydrophilic small-molecule drugs, hydrophobic drugs, and macromolecular protein drugs through an A-MN patch was 24.36, 17.47, and 5.36 times higher than that of free drug administration. A-MNs effectively maintained light transmittance of the cornea with a light transmittance of 96.33 to 100%, which was higher than that of S-MNs. Furthermore, A-MNs effectively avoided corneal tissue and nerve damage along with the pain. The efficiency and safety of A-MNs were also examined through both an in vitro cell experiment and an in vivo animal experimental model, which showed great potential in clinical application.
