P value was assessed by the Wilcoxon signed rank test (non-parametric); UT-DSAEK= ultra-thin Descemet stripping automated endothelial keratoplasty; DMEK= Descemet membrane endothelial keratoplasty; BCVA= best corrected visual acuity; logMAR= logarithm of the minimal angle of resolution; SIMK= K-value of simulated keratometry; Avg= average; Cyl= cylinder; D= diopters; ECD= endothelial cell density. Data are presented as mean ± standard deviation (SD). **p < 0.01
