What is keratoconus?
Keratoconus is an unusual condition that affects the structure of the cornea (the transparent part in the front of the eye).
As this disease progresses, the cornea slowly changes from a round to a conical shape. The eye protrudes and this causes vision problems. Generally, it affects both eyes, although the degree of progression may differ between them.
The thinning and deformation of the cornea cause a sudden increase in astigmatism, which cannot be treated with glasses because of its irregular condition. In this case, treatment can be carried out by fitting rigid contact lenses, specially designed for this condition, as a transitional but not definitive solution. Some patients also develop photophobia or light sensitivity.
In the initial stages of this condition, symptoms are mild but progressive. Visual acuity worsens and night vision problems occur.
