Endothelial keratoplasty: indications and outcomes in a tertiary care center in Lebanon.

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
objectiveThis study aims to assess the indications and outcomes of Descemet membrane endothelial keratoplasty (DMEK) surgeries in Lebanon, where tissues are imported. Focusing on visual acuity (VA) and central corneal thickness (CCT).
methodsThis retrospective chart review analyzed 86 DMEK surgeries performed on 78 patients between 2016 and 2023, examining CCT and VA measured preoperatively and up to one-year post-DMEK. Variables of interest included the rate of rebubbling, intraocular pressure (IOP), tissue preparation methods (preloaded, surgeon-prepared, or pre-stripped/precut tissue), donor age, donor endothelial cell count, time from death to preservation, time from preservation to surgery, and time from death to transplant. The goal was to explore the relationships between these variables and the clinical outcomes.
resultsThe most common indication for DMEK was pseudophakic or aphakic bullous keratopathy (PBK), followed by graft failure and Fuchs' endothelial corneal dystrophy (FECD). Significant improvements in VA and CCT were observed postoperatively (p < 0.001 and p ≤ 0.015 respectively). The mean IOP was 16.8 mmHg at baseline and 17.2 mmHg at 1 year post-operatively. The mean LogMAR score was 1.46 ± 0.16 at baseline, improving to 0.87 ± 0.21 at the 1-year follow-up. The rebubbling rate was 28.7%. Patients who required rebubbling had significantly higher central corneal thickness (CCT) during the first month (p = 0.027), but this difference was not observed over the course of the entire year. However, a notable incidence of postoperative new onset elevation in IOP was documented, affecting approximately 36.5% of patients.
conclusionDespite challenges posed by limited resources and economic constraints in Lebanon, DMEK surgery has shown promising outcomes in improving VA and CCT. Vigilant monitoring and management of postoperative complications, particularly elevated IOP, is essential. Addressing systemic barriers to healthcare access and enhancing corneal transplantation infrastructure are crucial for ensuring equitable delivery of advanced ophthalmic care in resource-limited settings.
