Abstract

This chapter discusses deep lamellar endothelial keratoplasty. Although full-thickness corneal transplantation is the gold standard procedure for the management of corneal diseases affecting clarity and visual function, there are some problems associated with the procedure. These include the need to use sutures and a full thickness corneal wound. The recent improvements in techniques for lamellar replacement of the anterior corneal layers also aid the development of a similar technique for the selective replacement of the diseased corneal endothelium. As the anterior layers remain undisturbed, there is no need for the use of corneal sutures as was used in traditional corneal transplantation. This provides early visual rehabilitation and reduced postoperative astigmatism. The corneal curvature also remains more stable over time and the large shifts in refraction that sometimes occur with corneal grafts do not occur. Large incision DLEK, small incision DLEK, and Descemet’s stripping endothelial keratoplasty are explained.
