A New Device and Method for Endothelial Graft Preparation in Descemet Membrane Endothelial Keratoplasty (DMEK): A Preliminary Feasibility and Technical Evaluation.
Article in Cureus, 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
backgroundThis study compares the preparation time and the macroscopic integrity of Descemet membrane and endothelium keratoplasty (DMEK) grafts prepared using the modified submerged cornea using backgrounds away (SCUBA) technique compared to those prepared with a newly developed artificial chamber device specifically designed for DMEK preparation. RESEARCH DESIGN AND
methodsThis is a prospective, comparative, randomized, and experimental study. Fifty corneas from 25 donors were used. The inclusion criteria were that both eyes were of the same donor, a scleral ring greater than 3 mm, and corneas unsuitable for clinical use. Preparation time and macroscopic tissue integrity were evaluated at the end of preparation.
resultsThe mean preparation time for both techniques was six minutes (p=0.2). The macroscopic integrity of the graft was similar between the inverted artificial chamber device and the modified SCUBA technique (p=1.00).
conclusionsThe upside-down artificial chamber operating with the upside-down cornea proved reproducible and macroscopically suitable for endothelial graft preparation for the DMEK technique.
