endothelial keratoplasty
Selective corneal transplantation technique replacing only the diseased endothelial layer.
Full Definition
Endothelial keratoplasty is a partial-thickness corneal transplantation procedure that selectively replaces only the diseased posterior layers of the cornea, including the endothelium, Descemet's membrane, and sometimes posterior stroma. This technique offers advantages over full-thickness penetrating keratoplasty including faster visual recovery, reduced risk of rejection, and maintenance of structural integrity. Common variants include Descemet's stripping endothelial keratoplasty (DSEK) and Descemet's membrane endothelial keratoplasty (DMEK). The procedure is indicated for endothelial dystrophies, bullous keratopathy, and other conditions affecting primarily the posterior corneal layers.
Usage
Usage note: Encompasses several specific techniques including DSEK and DMEK.
