Prescription patterns in DMEK: European survey.
Article in Journal of cataract and refractive surgery, 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
purposeTo assess current prescription patterns in Descemet membrane endothelial keratoplasty (DMEK) in Europe.
settingCountries affiliated with the European Cornea and Cell Transplantation Registry and the European Vision Institute Clinical Research Network.
designCross-sectional study (European survey).
methodsAn electronic survey was distributed to 16 national societies to gather data on prescription patterns for DMEK. Responses were categorized by 3 clinical goals: prevention of postoperative endophthalmitis, graft rejection, and pupillary block and glaucoma.
resultsResponses from 136 surgeons revealed that medication protocols mainly came from departmental protocols (54%) or personal experiences (48%) rather than national guidelines (22%) (multiple answers were allowed). Infection prevention primarily relied on intraoperative (72%) and postoperative (92%) antibiotics, with preoperative use less common (18%). Steroids were the mainstay for rejection prevention, used intraoperatively (59%), postoperatively (100%), and occasionally preoperatively (13%). Steroids were typically tapered to once daily after 6 months (46%) and discontinued after varying durations (65%). Dexamethasone was the preferred steroid. For high-risk DMEK, the most common approach was adding another topical (30%) or systemic immunosuppressive drug (24%), such as cyclosporine or mycophenolate. For graft rejection, most respondents increased topical steroid frequency (85%) or added (peri)bulbar steroid injections (42%). Pupillary block and glaucoma prophylaxis mainly involved intraoperative mydriatics (34%); intraocular pressure-lowering agents were rarely used (0.7% to 2.2%). For steroid-induced ocular hypertension, the common approach was switching to a lower-potency steroid (40%) or reducing steroid frequency (43%).
conclusionsCurrent prescription patterns in routine and high-risk DMEK vary significantly, reflecting the lack of standardized guidelines.
