Kerataconus
What is It?
This is a distortion of the cornea – the
cornea thins and becomes pointed and conical. The degree of ‘pointedness’
varies. In very severe cases the cornea becomes so elongated and thin
that it ruptures.
What Is The Effect On Vision?
Blurry vision that is not fully correctable
with glasses or regular contact lenses. There is usually shadowing
and a lack of crispness around objects.
What Is The Treatment?
There is no effective treatment to prevent or
cure Kerataconus. Some new surgical procedures are currently undergoing
trials. The main therapy is to restore vision to as best possible
using rigid gas permeable contact lenses to ‘mask’ the
distortion.
Who Is At Risk?
There is a genetic link. It is also more common
in those who are ‘atopic’. These are people who also suffer
from asthma, hayfever or eczema.
