KERATOCONUS

Keratoconus is a disease affecting the cornea of the eyes. Instead of being evenly rounded, the corneas reshape into a cone-like bulge. Light entering the eye is distorted by this misshapen cornea and so can’t be focused on the retina like it would with a healthy eye. The result is nearsightedness or even astigmatism.

For some people, this disease continues to develop over many year’s time. For others, it will progress to a certain point and then stop.

KERATOCONUS CAUSES AND SIGNS

Genetics may be a factor in developing keratoconus because this condition is often found in multiple members of the same family. It normally begins to show up in a person’s teens or 20s.

A person who sees the following signs should schedule an examination to be tested for keratoconus:

  • Unable to focus on far away objects or objects both near and far
  • Rapid changes in eyeglass prescriptions
  • Glare around lights
  • Light sensitivity
  • Sudden worsening of eyesight

 

The following factors may encourage the development of keratoconus:

  • Rubbing eyes excessively
  • Excessive exposure to ultraviolet rays from the sun
  • Poorly fitted contact lenses
  • Chronic eye irritation from environmental conditions
  • Having hay fever or asthma

 

TREATING KERATOCONUS

The first step of treatment is often fitting a patient with rigid, gas-permeable contact lens. This inflexible lens creates an even surface for light to pass through. But because the cornea under the lens is irregularly shaped, fitting a patient with the exact contact lens that’s right for them is a job for a specialist. Some people may even need specially designed contact lenses custom-fit to their corneas.

A scleral lens – one that rests on the white part of the eye (the sclera) – may be more comfortable for some patients because it does not rest on the cornea itself.

If the disease continues to progress, it might finally be necessary to perform a corneal transplant.
