Figure 6: Endothelial cells were counted in areas opposite of the mark (control) (a) and in the area where the mark was set (marked) (b). Endothelial cell loss was seen only at the contact zones between the Sinskey hook and the Descemet membrane in the near vicinity (brown areas). Mean endothelial cell density was reduced in the areas where endothelial cells were counted (c). Values are presented as mean ± SD relative to control, which was set 100% (, n = 6 per group). Scale bar = 100 μm.
