Descemet membrane endothelial keratoplasty information
Method of corneal transplantation
Descemet membrane endothelial keratoplasty (DMEK) is a method of corneal transplantation. The DMEK technique involves the removal of a very thin sheet of tissue from the posterior (innermost) side of a person's cornea, replacing it with the two posterior (innermost) layers of corneal tissue from a donor's eyeball. The two corneal layers which are exchanged are the Descemet's membrane and the corneal endothelium.[1] The person's corneal tissue is gently excised, peeled off, and replaced with the donor tissue via small 'clear corneal incisions' (small corneal incisions just anterior to the corneal limbus. The donor tissue is tamponaded against the person's exposed posterior corneal stroma by injecting a small air bubble into the anterior chamber. To ensure the air tamponade is effective, it is necessary for people to strictly maintain such a posture that they are looking up at the ceiling during the recovery period until the air bubble has fully resorbed.[1][2]
