The innermost layer of the cornea is called the endothelium. The endothelium is a carpet of cells that progressively die and are not rebuilt during life.
When the number of these cells is too low, the cornea loses its transparency. Following trauma, surgery or inflammation inside the eye, these cells can decrease in number.
The solution to the problem is surgery, namely: transplantation.
To carry out the intervention it is essentially necessary to eliminate the old internal layer and thanks to a small spatula that “scratches” the inner surface a cornea disk that was previously cut to size (whose thickness is about 80 microns) is inserted. Within a few days, the disk remains adherent and the cells resume their normal guaranteed corneal transparency.
Ultimately, this intervention allows you to retrieve fast visuals, and in the case of bad engraftment of the transplant, this can easily be replaced.
