Corneal cross-linking strengthens your cornea and halts the progression of keratoconus

Discover everything you need to know about cross-linking below

Keratoconus is a congenital eye disease in which the cornea becomes increasingly thinned and deformed into a cone.

This condition progresses steadily, and you will notice an increasing deterioration in your vision.

Corneal transplantation is a last resort treatment. In most cases, we can avoid transplantation with a treatment called cross-linking.

Dr. Victor Derhartunian was an early adopter of the cross-linking method and can use it in combination with laser treatment to improve vision.

A progressive corneal weakness manifests itself in increasing astigmatism and a steadily changing corneal topography. If the vision is impaired by this process, we can strengthen the cornea with cross-linking.

In the long term, this treatment can often flatten the cornea and making the eye suitable for vision correction treatments such as laser eye surgery.

We can determine your suitability for cross-linking treatment by examining your eyes at your initial assessment.

Cross-linking refers to the strengthening of the fibres of the cornea to stabilise the condition. We do this by applying a combination of riboflavin drops (vitamin B2) and UV irradiation.

Although this cannot reverse the disease, it can at least stop it in its existing state. In many cases, we can improve the irregular corneal shape.

Cross-linking can stop corneal weakness, which leads to stabilisation of the tissue.

Unfortunately, the treatment cannot improve vision.

To improve the vision, we can combine this procedure with other surgical techniques such as laser eye treatment. 

Alternatively, we can fit hard/scleral lenses to help maintain the structure of the cornea.

Cross-linking is now a widely used, safe and effective treatment to stop the progression of keratoconus. In addition to the general operational risks, side effects or complications with this method are unknown.

Today, the only way to stop keratoconus is with cross-linking. To achieve visual improvement, we recommend the following treatments:

Cross-linking has been an approved procedure since 2006. Its safety and effectiveness have been confirmed in numerous scientific publications. Medical experts are continuously developing this procedure to improve clinical results.

Cross-linking steps

The preparation

We first disinfect your facial area and give you a local anesthetic in the form of eye drops. We will then use a special device to fix your eyelids open. All of this is symptom-free and pain-free.

The riboflavin drops

First, we remove the top protective layer of the cornea (the epithelium) so that the eye drops can reach the next corneal layer (the stroma). We place the riboflavin eye drops in the eye for 30 minutes.

The UV radiation

We then apply UV light to the cornea for 10 minutes.

The conclusion

In the final step, we position soft bandage contact lenses to protect the eye after the operation. Drug treatment prevents inflammation and reduces postoperative pain. We will remove the protective lens after a few days.

How much do our patients love us?

95.89% to be precise. But don’t take our word for it…

I had been wearing contact lenses for 35 years. As I got older, the lenses bothered me more and more, especially in the summer months because of the increasing dryness in my eyes. As I’m very sporty, I was looking for another solution to avoid having to wear glasses. I was very scared and sceptical about this eye laser correction option.

EyeLaser Zurich gave me the feeling of being in the right place from the very first moment. The explanation was understandable and explained in detail. Everyone always took enough time for me. The consultations and the follow-up checks were excellent.

The result is a dream. It’s incredible to get up in the morning and see everything immediately without having to go to the bathroom first to put my lenses in. I am so grateful :-)

Top support, top service, top work!

That’s all I can say. I’m so grateful to have found my way to you. I’m extremely satisfied and will always be happy to recommend you. Everything is just great. Thank you so much!

I was initially unsure about laser eye surgery.

These worries were allayed during the very first information session. The whole team is very friendly and explained everything in detail. The operation went very quickly and I was able to see perfectly clearly again after just a few hours. The feeling of being able to see properly again is overwhelming and I recommend it to everyone! At EyeLaser in Zurich you are in the best of hands. Thank you very much.

Serious advice, good care, great success.
I no longer need glasses after the laser treatment.

Very competent consultation and super results following the operation. Since the first day after the operation, I can see perfectly without glasses. This has also been confirmed today, a little more than a year later, in the follow-up check-up.
