Descemet membrane endothelial keratoplasty

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 side of a person's cornea, replacing it with the two 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 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 posture so that they are looking up at the ceiling during the recovery period and until the air bubble has fully resorbed.[1][2]

Indications for DMEK include: [3]

Nomenclature

A minor variation to DMEK is the Descemet Membrane Automated Endothelial Keratoplasty (DMAEK), which involves automated preparation of donor tissue, using a microkeratome or femtosecond laser.[4]

gollark: Depends on what "psychological evaluation" actually means in practice.
gollark: I would assume it would be worsened if you fed in even more politically-relevant data.
gollark: Those NEVER pick up on human biases!
gollark: But what is considered a problematic political statement would be highly dependent on the political views of the people handling applications.
gollark: I didn't say extreme political views, I said political views in general.
