What is Keratoconus?

Keratoconus is a condition that occurs when the cornea of the eye, the clear dome shaped outer surface, becomes thin and develops into a cone shape. This alteration in the cornea causes vision to become blurred.

Usually, Keratoconus affects both eyes. This generally affects people between the ages of 10 to 25. The condition usually progresses slowly, over a period of 10 or more years.

What are the Symptoms of Keratoconus?

Symptoms of keratoconus can change as the disease progresses through its stages.

Symptoms include

  • blurred vision
  • distorted vision
  • sensitivity to light
  • sensitivity to glare
  • problems with nighttime driving
  • frequent changes in glasses or contact lens prescriptions
  • Clouding of vision

How is Keratoconus Treated?

It its early stages, keratoconus can be corrected with soft contact lenses, or with glasses. Over time, hard contact lenses may be necessary to correct vision. If the condition does progress to an advanced stage, a cornea replacement may be necessary.

Treatment will depend on the severity of your particular condition and how rapidly it is progressing. For example, mild to moderate keratoconus may stabilize after a few years. This can be treated with contact lenses or eye glasses.

For those with severe keratoconus, the cornea becomes scarred. Others, it eventually becomes difficult to wear contact lenses. For these people, surgery may become necessary.
