Keratoconus is a non-inflammatory eye condition in which the typically round, dome-shaped cornea progressively thins and weakens, causing a cone-like bulge of the cornea and optical irregularity. This can result in significant visual impairment and vision loss.


Keratoconus typically first appears in individuals who are in their late teens or early twenties, and may progress for 10 to 20 years, and then slow or stabilize. Each eye may be affected differently. In the early stages of keratoconus, people might experience:

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

The cornea is responsible for focusing most of the light that comes into the eye. Therefore, abnormalities of the cornea, such as keratoconus, can have a major impact on how an individual sees the world, making simple tasks such as driving a car or reading a book very difficult.


Treatment options for keratoconus focus on correcting the thinning and bulging of the cornea that contribute to distorted vision.

  • Eyeglasses or soft contact lenses
  • Rigid gas permeable contact lenses
  • Intac corneal inserts or implants
  • Corneal Cross-linking
  • Corneal Transplant Surgery
