People who have the eye condition keratoconus suffer from distorted vision. This happens because the cornea has become thin and bulgy; affecting the way that light hits the retina at the back of the eye.

The causes of this condition are relatively unknown, though there does seem to be a genetic factor. It is a progressive, degenerative disorder, usually beginning in the teenage years, often stabilising by age 35. The later stages of keratoconus are characterised by poor eyesight, in both the near and far ranges. Early detection is, therefore, very important to prevent advancement and deterioration of sight.

Symptoms include blurred vision and sensitivity to light and glare. Sometimes there is double vision,

astigmatism or a discoloured rim around the front of the eye (a fleischer ring). Keratoconus does not cause blindness, but vision can be severely impaired.

There is no cure for this condition but help can be found through corrective glasses or specially made scleral contact lenses. These special contact lenses made from advanced rigid gas permeable lens materials can assist the shaping of the cornea to allow better vision. Advanced cases may require surgery in the form of a corneal implant or transplantation (keratoplasty).

If you suspect Keratoconus, please call Insight Optometrists immediately for a thorough investigation.
