central corneal clouding clouding, central corneal Diffuse, hazy appearance of the cornea due to oedema of the central region of the cornea, usually associated with the wearing of hard contact lenses (mainly PMMA), but it may also occur in keratoconus, Fuch's endothelial dystrophy or disciform keratitis.
