(cornea disorder) Pathological process affecting the transparent anterior portion of the fibrous coat of the eye.

(corneal disorder) A non-neoplastic or neoplastic disorder that affects the cornea. Representative examples include keratitis, bullous keratopathy, and squamous cell carcinoma.

(corneal disorders) Your cornea is the outermost layer of your eye. It is clear and shaped like a dome. The cornea helps to shield the rest of the eye from germs, dust, and other harmful matter. It also helps your eye to focus. If you wear contact lenses, they float on top of your corneas. Problems with the cornea include Refractive errors; Allergies; Infections; Injuries; Dystrophies - conditions in which parts of the cornea lose clarity due to a buildup of cloudy material. Treatments of corneal disorders include medicines, corneal transplantation, and corneal laser surgery. NIH: National Eye Institute

Symptoms that suggest corneal involvement (eg, rather than simple conjunctivitis) include unilateral involvement, pain (foreign body sensation and ache--not just a gritty sensation), particularly with exposure to light (photophobia), and decreased visual acuity.
