corneal

 [kor´ne-al]
pertaining to the cornea.
corneal reflex a reflex action of the eye resulting in automatic closing of the eyelid when the cornea is stimulated. The corneal reflex can be elicited in a normal person by gently touching the cornea with a wisp of cotton. Absence of the corneal reflex indicates deep coma or injury of one of the nerves carrying the reflex arc.
corneal transplantation transplantation of a donor cornea into the eye of a recipient, done to improve the vision of patients with distorted curvature of the cornea (keratoconus) or corneal edema, infection, trauma, or intractable pain. Vision should improve beginning the day after surgery with optimal vision 6 to 12 months later. Because the cornea does not have a blood supply, corneal transplants were one of the earliest successful types of organ transplants. Called also keratoplasty.
