The median number of dead cells from 5 consecutive microscopic fields on each eye was 28 in the BAK
DTFC group and 2 in the PF DTFC group (p < 0.001).
The median number of dead cells from 5 consecutive microscopic fields on each eye was 28 in the BAK

The median number of TUNEL-positive endothelial cells, which were counted from 5 consecutive microsco-
pic fields (×400), was 4 in the BAK DTFC group and 0 in the PF DTFC group (p < 0.001).
