Corneal Cross-Linking

Overview

Corneal cross-linking uses riboflavin (vitamin B2) eye drops and ultraviolet light to strengthen the fibres of the cornea. It is the main treatment to halt progression of keratoconus.

Why it is done

• Keratoconus that is getting worse
• Thinning of the cornea after laser eye surgery

Before the procedure

An eye specialist measures the shape and thickness of the cornea. Contact lenses may need to be removed for a time before treatment.

During the procedure

Numbing drops are used. The riboflavin drops are applied, followed by ultraviolet light for a set time. The procedure usually takes about an hour.

After the procedure

A bandage contact lens is often placed. The eye may be painful and light-sensitive for a few days, and vision may be blurry for several weeks.

Risks

Risks include infection, haze, delayed healing and, rarely, damage to the cornea.
