A pre-Descemet’s endothelial keratoplasty graft has numerous advantages over a Descemet’s membrane endothelial keratoplasty graft.
The extra 10 µm to 15 µm of tissue that the pre-Descemet’s layer is composed of, while not significantly increasing the thickness as compared with a DMEK graft, gives the graft significant handling advantages by acting as a splint, making it a tougher tissue and also allowing the graft to be harvested from younger donor cornea.
A commonly used technique for identification of graft orientation in endothelial keratoplasty grafts such as
