  1. Data is shown by median (IQR) μm in 11 patients who underwent DSAEK.
  2. BSCVA, best-spectacle corrected visual acuity; DSAEK, Descemet stripping automated endothelial keratoplasty; IQR, interquartile range; logMAR, logarithm of minimal angle resolution; SA, spherical aberration.
  3. αP values: Mann–Whitney test. Bold numbers indicate P < 0.05.
