Corneal densitometry preoperatively and 4 months after Descemet membrane endothelial keratoplasty (DMEK) depending on edema severity. a Preoperative corneal density depending on the area of measurement divided into five annuli ranging from the most central surface (0–2 mm) to the most peripheral annulus (10–12 mm). b Corneal density depending on the area of measurement 4 months after DMEK divided into five annuli ranging from the most central surface (0–2 mm) to the most peripheral annulus (10–12 mm). c Preoperative corneal density depending on the layer of measurement divided into four layers: the anterior 120 µm of the cornea, the posterior 60 µm of the cornea and the central stroma between both layers with variable thickness depending on the total corneal thickness. d Corneal density depending on the layer of measurement 4 months after DMEK divided into three layers: the anterior 120 µm of the cornea, the posterior 60 µm of the cornea and the central stroma between both layers with variable thickness depending on the total corneal thickness. Blue colored bars represent Fuchs endothelial corneal dystrophy (FECD) eyes with preoperative subclinical corneal edema. Red colored cards reperesent FECD eyes with preoperative clinical corneal edema. Error bars = 95% confidence interval
