Conical cornea
(Keratoconus)
What is keratoconus?
Keratoconus is an eye condition that affects the cornea, making it become asymmetrical.. The cornea is the transparent, outermost part of the eye. Normally, the cornea is round. In the case of keratoconus, the structure of the cornea weakens, and therefore it loses its roundness and becomes more conical in shape. Because of this gradual deformation, the cornea thins and visual acuity decreases. In extreme cases, the cornea may even become cloudy and tear.
Symptoms of keratoconus
- Distorted vision
- Light sensitivity
- Light scattering
- Astigmatism
- Possible nearsightedness (objects or people at a distance appear blurred)
- Seeing a ‘fog’ (at an advanced stage)
Treatment of keratoconus
The diagnosis is made by carrying out various tests. The aim of the tests is, on the one hand, to correctly assess the irregularity of the cornea, and on the other hand, to carefully monitor the progression of the condition over time. The tests check what glasses prescription enable you to see the best. Moreover, the curvature of the cornea is measured and the cornea is imaged in three dimensions. Based on these tests, your eye doctor can detect any further deterioration of the condition very precisely at an early stage.
The aim of the treatment of keratoconus is twofold:
- Optimising your visual acuity
- Slowing or halting further deterioration
Optimising your visual acuity
In mild cases of keratoconus, vision can be improved effectively with glasses or contact lenses. For more advanced cases, special ‘scleral contact lenses’ are needed to restore visual acuity.
Slowing or halting deterioration
It has been shown that rubbing the eyes leads to further deformation of the cornea. Therefore, it is essential to avoid rubbing your eyes as much as possible. Your eye doctor will treat the underlying causes of itchy eyes.
In some cases, avoiding rubbing your eyes is not enough to stop the deterioration. In such situations, your eye doctor will discuss with you the possibility of a treatment involving corneal cross-linking.
What treatments do we offer?
- Corneal cross-linking
- Intacs
In this simple procedure, 2 tiny crescent-shaped implants are placed into the cornea to support the cornea and correct its shape. This will improve vision and increase the chance that you will be able to wear contact lenses again. After an Intacs procedure your eyesight may further improve for at least 6 months after the operation. Moreover, this is a reversible procedure, since the rings can easily be removed again.
How much does treatment of keratoconus cost?
During the consultation, we will discuss in detail the total cost of a potential treatment. For an overview, please go to our fees page.
