Note that 7 patients contributed eyes to two different study groups (study included a total of 115 patients).

Values are presented as means ± standard deviation.

CCT: central corneal thickness.

DMT: Endothelial/Descemet's membrane complex (En/DM) thickness.

DRI: En/DM rejection index, defined as DMT divided by CCT multiplied by 33.
