What is the cornea?

The cornea is the transparent, dome-shaped, outermost layer that covers the iris and pupil in the front of the eye. The cornea does not contain blood vessels to nourish or protect it against infection. It receives its nourishment from the tears and fluid that fill the chamber behind it.

The cornea shields the eye from dust, germs, and other harmful matter and it is the entry point for light into the eye. When light strikes the cornea, it bends, or refracts, the incoming light onto the lens. The lens further refocuses the light onto the retina, a layer of light-sensing cells lining the back of the eye.

You could say the cornea and lens in the eye act like a camera’s lens, with the retina being the film. If the cornea is unable to focus the light properly, the retina receives a blurry image.


What is Corneal Disease?

Corneal and external diseases involve the cornea, anterior chamber of the eye, iris, lens, conjunctiva and eyelids. These diseases include:

  • Cataracts
  • Corneal allergies
  • Infections and irregularities
  • Refractive errors (nearsightedness, farsightedness and astigmatism)
  • Conjunctivitis (pink eye)
  • Dry eye
  • Tear disorders
  • Keratoconus, pterygium, endophthalmitis, Fuch’s Dystrophy and others


What is a corneal transplant?

A Corneal Transplant or Penetrating Keratoplasty (PKP) is the procedure used to replace a scarred or damaged cornea.
