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.

Overall I’m more than satisfied.

The entire team is friendly, competent and very well organized. My quality of life without lenses and glassed has increased significantly. I would do it again and definitely recommend it.

DocFinder User

Everyone who is thinking about having their eyes lasered should come here!

I have been seeing PERFECT since then and am extremely satisfied with the result. Highly recommended and personally regret not having done it earlier. A completely different attitude towards life of not having to wear glasses anymore.

DocFinder User

The operation was short and painless.

Even after the operation, I had no pain or other impairments. The entire team is extremely friendly and helpful. Since I am completely satisfied with the result, I can only recommend EyeLaser.

DocFinder User

The doc is super friendly, very professional and really tip-top.

I was able to see very well 4 hours after the procedure. I was a little light-sensitive for a few days, which I was made aware of in advance. I am very pleased. The only annoying thing is that I didn’t do it earlier.

DocFinder User

My quality of life has increased immensely after the laser, despite “not that many diopters”.

A big THANK YOU for that! I can only warmly recommend the clinic.

DocFinder User

I’ve been wearing glasses for 40 years, and I don’t regret taking this step much earlier.

I had no problem with the healing process and have been enjoying my life without glasses ever since.

DocFinder User

It was the best decision of my life.

After laser eye surgery, my ametropia was completely eliminated, and I was able to see everything razor-sharp the day after the operation. The doctor and his entire team are super nice and professional.

DocFinder User

The most popular ophthalmologist in Austria.

Dr. Victor Derhartunian hasn’t got such great customer reviews for nothing. He is clearly the nicest doctor in his field in the city. I am 57 years old, and five years ago, I had my eyes lasered in his eye laser practice. The result is brilliant. I still have good eyesight, I only need glasses for reading now, but presbyopia is a completely natural process that everyone sooner or later succumbs to.

DocFinder User

Thanks also to the entire team, everything went really well.

At first, I was very sceptical about lasers. After the laser, I was able to see straight away without reading glasses. I am happy to have taken the step and Dr. Derhartunian can only be recommended.
