The cornea is the transparent front part of the eye that covers the iris, pupil, and anterior chamber. The cornea, with the anterior chamber and lens, refracts light, with the cornea accounting for approximately two-thirds of the eye's total optical power. Various disorders affecting the cornea can lead to pain, irritation, reduced vision, and sometimes blindness.

  • Corneal abrasion - a medical condition involving the loss of the surface epithelial layer of the eye's cornea as a result of trauma to the surface of the eye.

  • Corneal dystrophy - a condition in which one or more parts of the cornea lose their normal clarity due to a build-up of cloudy material.

  • Corneal ulcer - an inflammatory or infective condition of the cornea involving disruption of its epithelial layer with involvement of the corneal stroma.

  • Corneal neovascularization - excessive ingrowth of blood vessels from the limbal vascular plexus into the cornea, caused by deprivation of oxygen from the air.

  • Fuchs' dystrophy - cloudy morning vision.
