Low endothelial cell count and clear corneal grafts.

Specular microscopic study on clear corneal grafts indicates that at times surprisingly low endothelial cell density can maintain the grafted cornea in a relatively dehydrated state. The critical limit of the endothelial cell count for corneal decompensation is thought to be 700 cells/mm2. This communication reports 13 cases of clear corneal graft with endothelial cell count below 700 cells/mm2.
