What are the main types of corneal conditions?

There are several common conditions that affect the cornea.

Injuries: Small abrasions (scratches) on the cornea usually heal on their own. Deeper scratches or other injuries can cause corneal scarring and vision problems.

Allergies: Allergies to pollen can irritate the eyes and cause allergic conjunctivitis (pink eye). This can make your eyes red, itchy, and watery.

Keratitis: Keratitis is inflammation (redness and swelling) of the cornea. Infections related to contact lenses are the most common cause of keratitis.

Dry eye: Dry eye happens when your eyes don’t make enough tears to stay wet. This can be uncomfortable and may cause vision problems.

Corneal dystrophies: Corneal dystrophies cause cloudy vision when material builds up on the cornea. These diseases usually run in families.

When to get help right away:

  •   Intense eye pain
  •   Change in vision
  •   Blurry vision
  •   Very red, watery eyes
  •   An object stuck in your eye
  •   A serious eye injury or trauma — like getting hit hard in the eye

To prevent corneal injuries, wear protective eyewear when you:

  •   Play sports that use a ball or puck, like baseball or hockeyDo yardwork, like mowing the lawn or using a weedwhacker
  •   Do yardwork, like mowing the lawn or using a weedwhacker
  •   Make repairs, like painting or hammering
  •   Use machines, like sanders or drills
  •   Use chemicals, like bleach or pesticides

If you wear contact lenses, always follow the instructions to clean, disinfect, and store your lenses. This can help prevent corneal infections, like keratitis.

  •   Feel like something’s stuck in your eye?
  •   Try blinking several times
  •   Try rinsing your eye with clean water
  •   Don’t rub your eye — you could scratch your cornea
  •   If an object is stuck in your eye, don’t try to remove it yourself — go to your eye doctor or the emergency room

What is the treatment for corneal conditions?

Many corneal conditions can be treated with prescription eye drops or pills. If you have advanced corneal disease, you may need a different treatment.

Laser treatment: To treat some corneal dystrophies and other conditions, doctors can use a type of laser treatment called phototherapeutic keratectomy (PTK) to reshape the cornea, remove scar tissue, and make vision clearer.

Corneal transplant surgery: If the damage to your cornea can’t be repaired, doctors can remove the damaged part and replace it with healthy corneal tissue from a donor.

Artificial cornea: As an alternative to corneal transplant, doctors can replace a damaged cornea with an artificial cornea, called a keratoprosthesis (KPro).

Keratoconus

Your cornea is the clear, dome-shaped window at the front of your eye. It focuses light into your eye. Keratoconus is when the cornea thins out and bulges like a cone. Changing the shape of the cornea brings light rays out of focus. As a result, your vision is blurry and distorted, making daily tasks like reading or driving difficult.

Management

Keratoconus can be diagnosed through a routine eye exam. Your ophthalmologist will examine your cornea, and may measure its curvature. This helps show if there is a change in its shape. Your ophthalmologist may also map your cornea’s surface using a special computer. This detailed image shows the condition of the cornea’s surface.

How Is Keratoconus Treated?

Keratoconus treatment depends on your symptoms. When your symptoms are mild, your vision can be corrected with eyeglasses. Later you may need to wear special hard contact lenses to help keep vision in proper focus.

Here are other ways that your ophthalmologist might treat keratoconus

Intacs: This is a small curved device that your ophthalmologist surgically puts in your cornea. Intacs help flatten the curvature of your cornea to improve vision.

Collagen cross-linking: Your ophthalmologist uses a special UV light and eye drops to strengthen the cornea. Doing this helps to flatten or stiffen your cornea, keeping it from bulging further.

Corneal transplant: When symptoms are severe, your ophthalmologist may suggest a corneal transplant. Your ophthalmologist replaces all or part of your diseased cornea with healthy donor cornea tissue.

Do not rub your eyes!

With keratoconus, try to avoid rubbing your eyes. This can damage thin corneal tissue and make your symptoms worse. If you have itchy eyes that cause you to rub, speak to your ophthalmologist about medicines to control your allergies.
