Lumican and keratocan have been shown to be significantly decreased in KC [152, 153], yet keratocan has been reported to be highly expressed in the stroma of KC compared to normal or other diseased cornea samples, such as from Fuchs' corneal dystrophy or pseudophakic bullous keratopathy patients [154]. Here, KERA is linked to Fuchs' endothelial dystrophy.
