| Summary: | This video will demonstrate the steps to performing a PDEK graft: loading the graft, making a bubble, preparing the recipient eye, and closing the incision. As the names imply, DMEK refers to transplantation of the Descemet's Membrane and endothelium whereas PDEK refers to transplantation of pre-Descemet's layer, Descemet's membrane and endothelium. The video will carefully demonstrate PDEK technique, which offers the ability to use young donor grafts with a greater volume of endothelial cell transfer. In addition, the pre-Descemet's layer gives a splinting effect to the graft that allows it to be handled more easily and surgery to be completed faster and more successfully than a DMEK graft. The air pump assisted PDEK and the endoilluminator assisted PDEK techniques that help increase success of surgery will also be discussed in the video, along with further references for the viewer interested in learning more.
