Common Cornea Problem

Keratoconus

What is it?

Keratoconus is a type of eye disease which progressively thins the cornea and changes its shape. This disease changes the curvature of the cornea, resulting in irregular astigmatism and myopia which causes distortion of vision.

Symptoms

In the early stages, Keratoconus can cause the following:

  • Slight blurring
  • Distortion of vision
  • Increased sensitivity to glare and light

In a small number of cases, the cornea will swell and cause a sudden and significant decrease in vision.

Treatment

In the early stages, glasses or soft contact lenses can be used to correct the nearsightedness and astigmatism. As the disorder progresses, vision deteriorates, the cornea continues to thin, and rigid gas permeable contact lenses may be needed to correct vision. In advanced cases, a corneal transplant may be necessary to replace the damaged cornea.
