What is keratoconus and what are the keratoconus symptoms?

In this post, Dr Nick Toalster explains what keratoconus is and what symptoms people with keratoconus suffer from.

What is keratoconus?

Keratoconus is a change in the shape of the cornea, which is the front lens of the eye. As that change in shape occurs, it distorts the optics and results in blurry vision. Because the optics are very abnormal, even glasses may not be able to correct your vision and this leads to eye strain and headaches. So the symptoms of keratoconus are often noticed in early adulthood, or even as a teenager.

What are the symptoms of keratoconus?

You may experience glare and halos, blurred vision, difficulty with oncoming traffic lights at night, or difficulty on computer screens with pixelation. This can result in headaches, eye strain, and gradual deterioration of your ability to do your normal tasks of daily living.

We’d like to invite you to book a consultation with us.
