Keratoconus

Keratoconus is a condition of the eye that occurs when your cornea thins and bulges out into a cone shape. This condition often affects both eyes, but one eye is usually worse than the other. Fortunately, the professionals at The Center for Corrective Surgery can treat the symptoms of keratoconus and improve your vision.

Who Is At Risk For Keratoconus?

Certain factors increase your risk of developing keratoconus, including:

  • Family history of keratoconus: Around 1 in 10 people with keratoconus also have a parent with this condition.
  • Medical conditions: Certain medical conditions can cause keratoconus, including hay fever, asthma, retinitis pigmentosa, Down syndrome, and Ehlers-Danlos syndrome.
  • Frequent vigorous rubbing of the eyes.

Symptoms of Keratoconus

Keratoconus causes several symptoms that affect your vision. As the condition progresses, the symptoms become more severe. Symptoms include:

  • Blurry vision
  • Distorted vision
  • Sensitivity to bright light and glare
  • Trouble driving at night
  • Needing to change your eyeglass prescription frequently
  • Sudden worsening of vision
  • Sudden cloudy vision

How Is Keratoconus Diagnosed?

Keratoconus can be diagnosed during an annual eye exam. During your exam, our eye doctor will perform a slit-lamp exam to get a good look at the shape of your cornea. We will also perform a refraction to determine if your vision has changed since your last visit. If our eye doctor suspects you have keratoconus, they will perform a couple of additional tests:

  • Keratometry: This test allows our eye doctor to determine the basic shape of your cornea.
  • Computerized corneal mapping: This is a photographic test that can detect the early signs of keratoconus.

Keratoconus Treatment

In the early stages, our eye doctor will increase your prescription to correct your vision. As the condition progresses, other treatment options may be utilized, such as:

  • Gas permeable lenses: Gas permeable lenses are rigid and can help hold your cornea's round shape.
  • Piggyback lenses: If you cannot get used to gas permeable lenses, our eye doctor can prescribe a soft lens to wear underneath, which will act as a cushion, making them more comfortable.
  • Hybrid contacts: Hybrid lenses are another option if you cannot get used to gas permeable lenses. A hard inner lens is surrounded by a soft outer ring.
  • Scleral contacts: These are used for advanced cases. The contacts sit on the white of the eye and vault over the cornea without touching it.
