Abstract

The description of the pre-Descemet’s layer (PDL) brought with it the opportunity to perform a new kind of endothelial transplantation, which included transplantation of the Dua’s layer or the PDL together with the Descemet’s membrane (DM), and endothelial cells. This procedure was termed as pre-Descemet’s endothelial keratoplasty (PDEK). This chapter aims to cover discussion on air pump-assisted PDEK and presents a detailed description on this technique. As compared to DMEK, PDEK gives the ability to use younger grafts thus giving a higher initial count of endothelial cells to start out with. This makes the graft less susceptible to both primary and secondary graft failure. Despite being more robust, the PDEK graft still behaves like the DMEK graft does in terms of graft handling, complete graft unfolding including edge unfolding, graft centration, graft adhesion, etc. Advantages and some tips and tricks of air pump-assisted PDEK are also provided in this chapter.
