Corneal Collagen Cross-linking

The cornea is mostly made of collagen fibres which are arranged in bundles. Its strength and rigidity are partly determined by how strongly these fibres are linked together.

In corneal ectasia, the cornea is weakened either:

What is Keratoconus?

Keratoconus is a very uncommon eye disease and is caused by an irregularly thinned cornea. The keratoconic cornea is distorted and bulges forward. This condition can be picked up by performing a corneal topography.

How is Keratoconus Treated?

In mild cases, keratoconus can be managed by:

If vision can no longer be corrected by spectacles or contact lenses, you may be advised to undergo surgery such as:

What is Corneal Collagen Crosslinking (CXL)?

Corneal collagen crosslinking (CXL) is a superficial treatment to strengthen the weakened cornea.

How is it done?

The procedure takes approximately 30 minutes.

During the first few days after the surgery, the eye will be slightly sore and teary. The patient will experience minimal haziness of vision (most patients do not notice the haziness) for a few months after CXL. By 6 months, the hazy vision is usually gone.

What is the effect of CXL on keratoconic and post-LASIK ectasia patients?

New developments in the treatment of ectasia

As an adjunct to corneal collagen crosslinking, the cornea can be reshaped with a topography-guided or corneal wavefront-guided laser. This improves the shape of the cornea before strengthening it. The visual results of this kind of therapy are generally superior to corneal collagen crosslinking done alone.
