- P value was assessed by the Paired-t test for BCVA, pachymetry and donor age, and by the Wilcoxon signed rank test (non-parametric) for graft ECD and diameter. 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; y= years; ECD= endothelial cell density. Data are presented as mean ± standard deviation (SD)
