Comparative Study of Corneal Endothelial Cell Damage after Femtosecond Laser Assisted Deep Stromal Dissection
Figure 5
Histological evaluation and TUNEL assay of endothelial cells after femtosecond laser cutting. (a) The corneal stroma was edematous and only a small number of keratocytes and endothelial cells could be found in the 50 μm group. (c) Most of the deep stromal cells and the endothelium of the 150 μm group were intact and only swollen changes could be seen in the 150 μm group. (e) No endothelium damage or swollen changes could be observed in the control group. (b) There were many TUNEL positive cells in the 50 μm group. ((d) and (f)) No TUNEL positive cells were found in the 150 μm group or the control group.
