What is the Descemet membrane endothelial keratoplasty ( DMEK ) procedure?

Descemet Membrane Endothelial Keratoplasty (DMEK) DMEK is a partial-thickness cornea transplant procedure that involves selective removal of the patient’s Descemet membrane and endothelium, followed by transplantation of donor corneal endothelium and Descemet membrane without additional stromal tissue from the donor.

How long after DMEK can a cornea be grafted?
