What is Keratoconus?

Keratoconus (KCS) is a degenerative condition of the cornea where thinning of the cornea (ectasia) occurs. It usually develops in your teens or twenties and can become worse over time.

When the cornea thins in this way it will bulge outwards in an irregular cone shape and can no longer focus a clear image on your retina, resulting in distorted and blurry vision.

If untreated, progressive sight loss can occur. Over time you might not be able to achieve clear vision with glasses and may need to wear rigid contact lenses. Without treatment, the shape of the cornea can continue to worsen meaning you would eventually need a corneal transplant.

What is Corneal Collagen Cross Linking for Keratoconus?

Corneal collagen crosslinking (CXL) is a treatment, which can prevent keratoconus getting worse .It is successful in more than ninety percent of cases.

The procedure is normally carried out under local anaesthetic.

Vitamin B2 drops (Riboflavin) are dropped onto the cornea where they will sit for around twenty minutes.

Ultraviolet light is shone onto the drops for around ten minutes, which causes the collagen fibres that make up your cornea to form extra connections between each other.

The result of the formation of these extra connections is that your cornea becomes stronger.
