DMEK endothelial corneal transplant (each eye)

The cornea is the transparent external lens on the front of the eye. Corneal transplantation or keratoplasty consists of the replacement of damaged or diseased corneal tissue by healthy corneal tissue from a donor, the corneal endothelial transplant replaces only the posterior layers of the patient's cornea (Endothelium and Descemet) and preserves the rest of the layers (Stroma, Bowman and Epithelium).
