Comparative Study of Corneal Endothelial Cell Damage after Femtosecond Laser Assisted Deep Stromal Dissection

Figure 4

Representative images from scanning electron microscopy (SEM) of endothelial cells in the cutting area after femtosecond laser cutting. ((a) and (b)) The laser created a substantial endothelial damage area in the 50 μm group. The damaged endothelium presented with many small cavities resembling holes in a sponge, and the normal hexagonal structure was destroyed. ((c) and (d)) Only sporadic cells presented with swollen changes in the 150 μm group. ((e) and (f)) No obvious damage was noted in the control group.
