Descemet or dmek membrane endoterlial keratoplasty

What is descemet’s membrane endothelial keratoplasty?

Descemet membrane endotherlial keratoplasty or dmek is a type of partial corneal transplant that consists of replacing the innermost diseased cell layers of the cornea with healthy ones from a donor, without affecting the middle layers.

In which cases is it done?

Descemet membrane endothelial keratoplasty is performed in most patients with corneal endothelial injury (posterior corneal transplant) It is rarely used because it is a complex procedure.

Previous exams

A complete ophthalmological examination is necessary prior to surgery.

The intervention

The surgery is microscopic through microincisions, and the diseased layers of the patient are replaced by the healthy ones of the donor. This surgery is characterized by a much faster recovery than with conventional corneal transplantation.


Like all surgery, it has risks of complications after it (infections, rejection, granuloma…).
