What Is Keratoconus?

Keratoconus is a disorder of the eye that results in thinning of the cornea (the colourless dome that covers the iris) leading it to have an irregular shape – specifically a cone shape . Usually both eyes are affected.

This can be diagnosed and monitored using a special piece of equipment called a corneal topographer. And yes, of course we have one at EDGE.

Keratoconus Symptoms

Symptoms are likely to include:

  • Blurry vision

  • Short-sightedness

  • High levels of astigmatism (irregular curve to front surface of eye)

  • Light sensitivity

Keratoconus Causes

While the cause is unknown, it is believed to occur due to a combination of genetic, environmental, and hormonal factors. Patients with a parent, sibling, or child who has keratoconus are more at risk. The environmental factors are thought to include rubbing the eyes and allergies.

Keratoconus Treatment

We would assess you early on to see if a minor surgical/implant procedure could be effective in slowing down the progression of the condition. We can advise whether this may be of benefit and refer you to a specialist who can discuss this with you.

Often in early Keratoconus a glasses or traditional contact lenses will be sufficient. In more advanced cases there are various types of specialised contact lenses (that we can fit and supply) that can provide an excellent level of vision without the need for surgery.

Very advanced cases may need a corneal transplant, but these cases are rare nowadays.
