Corneal collagen cross-linking uses ultraviolet light and a photosensitizer to strengthen chemical bonds in the cornea.
Keratoconus is a dystrophic disorder where structural changes occur within the cornea causing it to stretch and develop an abnormal thin and cone shape. It is diagnosed in the patient’s adolescent years and presents with blurred vision, ocular irritation and the need for increasingly strong glasses or contact lenses to see correctly.
If present in both eyes, the deterioration in vision can affect the patient’s ability to drive a car or read normal print.
You might experience the following symptoms:
Keratoconus can now be treated with a non-surgical procedure called cornea collagen cross-linking. The procedure can be performed under topical anaesthetic and takes approximately 30 minutes per eye.
No overnight stay is required. Once you’re ready to be discharged, you’ll need to arrange a taxi, friend or family member to take you home because you won’t be able to drive. You should also ask them to help with shopping and cleaning for a few days, as your vision may take a while to return to normal.
Keratoconus is a condition that causes the cornea, the transparent front part of the eye to weaken, get thinner and change shape. It affects about one in 2,000 people. The exact cause of the condition is unknown. It's possibly passed down through the family.
Keratoconus is one of the most common reasons for corneal transplantation in younger patients. It doesn’t usually appear until the early teens, but can occur earlier in a few patients. Many cases of keratoconus are mild and can be managed by using contact lenses or glasses. But in some patients it can progress to the point where a corneal transplant is necessary.

Keratoconus can be treated with a non-surgical procedure called cornea collagen cross-linking. A solution called riboflavin is soaked in to the cornea of the eye after delicately removing the surface layer of cells, this solution is then activated by illumination with ultra violet light from a laser.
The riboflavin absorbs the UV energy and creates free radicals and oxidative stress that leads to the formation of chemical cross-links between the structural collagen fibres of the cornea.
These cross-links increase the strength of the cornea and prevent it from stretching anymore thereby halting the progression of keratoconus.
The procedure can be performed under topical anaesthetic and takes approximately 30 minutes.
Corneal collagen cross-linking (CXL) is currently the best available treatment for keratoconus. This technique uses ultraviolet (UV) light and a photosensitizer (riboflavin) to strengthen chemical bonds in the cornea. It was first developed in Germany in 1998 and clinical trials have been in course since then.
You will be given a pre-operative preparation in the form of oral sedation and analgesia and in some cases you may require an eye drop to constrict the pupil.
Once in theatre your surgeon will give anaesthetic drops to numb the outer surface of the eye.
Your vision will be blurred for the first 4 days, after which time the bandage contact lens will be removed. Moderate discomfort should be expected for the first 24-72 hours, which can be controlled by pain relief.
You may also suffer from red and watering eyes and light sensitivity.
You will be given a large amount of eye drops to take home which will aid your recovery.
You will be able to go home on the same day as your treatment: however you'll need someone to accompany you as your vision will be impaired. The surgeon will have inserted a bandage contact lens for comfort and your eye will be covered by a protective shield.
You will be given several drops to take home which will start on the same day as procedure. These will help the eye to heal and prevent infection and for pain relief.
You may experience moderate discomfort the first 24-72 hours following the procedure. You will be given eye drops and oral analgesia to help with this.
Your nurse will show you how to put these in and give you an advice about caring for your eye. You may find it helpful to wear sunglasses when you leave the hospital as your eyes will be sensitive to the sunlight.
Before leaving the hospital you will be given a date for a follow up appointment with your surgeon to remove the bandage contact lens. Try not to touch or rub your eye. Expect to have blurred vision for a few days – this will start to improve once the bondage contact lens is removed.
How soon you can go back to work depends on the nature of the job. Your surgeon will give you advice about when you can resume driving if you have no other eye condition.
After you leave hospital
