Corneal Cross-Linking: Suitability, Risks and Follow-Up

Corneal cross-linking uses riboflavin and ultraviolet light to strengthen corneal tissue. Its main purpose is usually to slow or stop progression of keratoconus or another corneal ectasia; it does not guarantee improved unaided vision or freedom from glasses or contact lenses.

Assessment and suitability

Assessment should confirm progression and include corneal mapping and thickness, refraction, eye health, age, pregnancy status, previous surgery and ability to follow aftercare. The surface layer may be removed or left intact depending on the protocol, with different evidence and limitations.

Risks and alternatives

Risks include pain, light sensitivity, haze, infection, delayed surface healing, scarring, loss or change of vision, treatment failure and need for further care. Alternatives depend on progression and may include monitoring, glasses, contact lenses, intracorneal procedures or corneal transplantation.

Follow-up

Vision may fluctuate while the cornea heals. Increasing pain, redness, discharge or worsening vision requires urgent assessment. Follow-up imaging is needed to evaluate stability; a single early result cannot establish long-term success.

NICE guidance on corneal cross-linking discusses evidence and governance for the procedure.
