Cornea Q & A

What does the cornea do?

Your cornea is the clear coating on the outside of your eye. It focuses light so you can see clearly and protects the structures in your eyes from hazards like dirt and germs. It also filters out some of the ultraviolet light from the sun.

The cornea has a curved, dome-like shape, which determines how well it can focus light. If you have a refractive error, like nearsightedness, farsightedness, or astigmatism, it’s likely your corneas don’t have an ideal curve or symmetry. If disease, injury, or infection damages your cornea, you may suffer from problems with your vision, including distortions and cloudiness.

Though your cornea is good at healing itself, some cornea problems are more serious and require treatment. Symptoms of cornea problems include:

  • Pain
  • Scarring
  • Sensitivity to light
  • Blurred vision
  • Watery, red eyes
  • Eye discharge

Schedule an appointment with Dr. Shakir right away if you’re experiencing discomfort or vision changes.

What conditions affect the cornea?

Conditions that affect the cornea include:


Keratitis is a painful inflammation of the cornea that results from injury or bacterial or fungal infection. You may be more likely to get it if you wear contact lenses.


Keratoconus is when your cornea becomes thinner and changes shape. This causes your vision to worsen. You can’t correct it with glasses or regular contact lenses.

Corneal abrasion

A corneal abrasion is a scratch to your cornea. Though often mild, some cause severe pain and can lead to infection.

Conditions like dry eyes and eye allergies can irritate and inflame your corneas.

Though some cornea problems happen suddenly, they often develop slowly. Dr. Shakir uses advanced imaging technology, including optical coherence tomography and topography, to detect early changes to your cornea that result from corneal disease.

How are corneal problems treated?

Treatment for cornea problems depends on the condition. Infections and inflammations may be treatable with eye drops. If you have an abrasion, you may need to protect your eye while it heals.

Conditions that change the shape or function of your cornea may require more advanced treatment. If you have keratoconus or another condition that affects the shape of your cornea, you may benefit from scleral contact lenses. Scleral lenses can correct your vision even if you can’t wear regular contacts.

Dr. Shakir also performs procedures to fix damaged corneas. He can replace your cornea with healthy transplanted tissue or an artificial cornea. Laser therapy can restore the shape of your cornea or remove scar tissue.
