What is Keratoconus?

Keratoconus is a condition in which the cornea, the clear tissue in front of the coloured part of the eye, becomes thin and distorted in shape. Keratoconus does not lead to blindness but the corneal distortion will cause a decrease in your vision. Initially this condition can be treated with spectacles but, as it progresses, rigid hard contact lenses are needed to correct vision effectively. Sometimes, in the early stages, soft lenses can be used successfully.

How do I know I have this?

Usually the first awareness comes through having to change your spectacle prescription too frequently and from not achieving good vision even when the best spectacle correction is worn.

What causes it?

There does not appear to be any single cause for keratoconus. Our recent research has confirmed that allergy and frequent eye rubbing are commonly found among people with keratoconus.

If you have this condition?

Please come in for a full assessment of your eyes and vision. There are a number of special tests we can perform to determine or confirm if you have keratoconus including computerised video-keratoscopy. This is the most modern and sensitive means of detecting the characteristic corneal shape changes. If keratoconus is confirmed, we will discuss the alternative options for your management in order that the best possible management is maintained. If you have any questions we will be please to discuss them with you.
