Simulation of Keratoconus Patient Vision

What Is Keratoconus?

Keratoconus, meaning “cone-shaped,” is a condition in which the cornea (the clear front window of the eye) progressively becomes steeper and thinner. This abnormal shape of the cornea can cause distortion of visual images.

Keratoconus almost always effects both eyes, but usually one eye will advance sooner than the other.

What Causes Karatoconus?

The cause of keratoconus is unknown. It usually appears in individuals during their late teens or early twenties. The disease usually progresses for 10 to 20 years as the cornea steepens and thins. Although both eyes may be affected, one eye is usually worse than the other.

What  Keratoconus is not completely known, but this condition is not rare. Some studies show that Kerataconus affects 1 out of every 2,000 people. It’s generally first diagnosed in young people at puberty or in their late teens. At this stage, Keratoconus causes slight blurring and distortion of vision and increased sensitivity to light. Keratoconus may progress for 10-20 years and then slow or stabilize.


  • Frequent changing of glasses or contact lens prescriptions with high levels of astigmatism
  • Blurring and distortion of vision
  • Glare
  • Light sensitivity and irritation


Signs of keratoconus can be seen during a routine eye examination. The diagnosis is often confirmed using corneal topography which are photographs that measure the curvature of the cornea.

Although there are no medicines known that will prevent progression of the disease, mild cases of keratoconus can be successfully treated with glasses or specially designed contact lenses. Advanced cases may require Corneal Crosslinking or Intacs which are corneal ring implants.

Many insurance companies cover keratoconus treatment. Our better vision team can explain all the options available.
