Evaluation of the corneal endothelium in clear grafts after deep anterior lamellar keratoplasty using specular microscopy.
Article in International ophthalmology, 2026. 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 evaluate postoperative endothelial cell function and corneal transparency in patients who underwent deep anterior lamellar keratoplasty (DALK) due to keratoconus (KC), macular corneal dystrophy (MCD), lattice corneal dystrophy (LCD), or corneal scarring.
methodsThis retrospective study included 55 eyes of 55 patients who underwent DALK between 2014 and 2023 and 56 eyes of 56 healthy individuals as controls. Endothelial cell density (ECD) and cell morphology were assessed using specular microscopy, and corneal densitometry measurements were obtained using Pentacam at postoperative months 1, 6, and 12. Outcomes were compared between the patient and control groups and among diagnostic subgroups within the DALK cohort.
resultsAt postoperative month 1, corneal densitometry values were significantly higher in the DALK group compared with the control group (p < 0.0001). Endothelial cell density was significantly lower in the DALK group than in controls (p < 0.0001). No significant difference in ECD was observed among the diagnostic subgroups (KC, MCD, LCD, and corneal scarring) (p = 0.367). In the MCD group, anterior and central 0-2 mm densitometry values at postoperative month 1 were significantly higher than those in the KC and LCD groups (p = 0.026); however, no significant differences were observed at months 6 and 12.
conclusionsAlthough endothelial cell density was reduced in all diagnostic groups after DALK compared with healthy controls, adequate endothelial cell function was preserved. The preservation of endothelial function in patients with macular corneal dystrophy indicates that DALK can be safely performed in this patient population.
