Glanatec is assisting with my FED. But research seems to be concentrated on its effect on endothelial cells. Focus impairment is associated with bullae distorting the epithelial layer. These effects vary in a cycle as epithelial cells are shed or major bullae become ruptured. Is there any research on improving epithelial adhesion to the underlying layer? Can the permeability of the epithelial layer be enhanced to increase the effectiveness of osmosis when a saline solution is used or of evaporation?
