Keratoconus
The cornea is the clear window of the eye. The centre is spherical (round), flattening out towards the periphery. Keratoconus is a condition where the cornea is cone shaped and the surface is also irregular resulting in a distorted vision. It commonly affects both eyes with one eye worse than the other. The exact cause is still unknown.
Many people are initially unaware they have keratoconus and see their eye doctor because of progressive changes in their spectacle prescription, but despite accurate measurements, vision is still poor
In more advanced keratoconus, glasses or soft contact lens may not adequately correct the vision. The vast majority of patients, however, can be treated with rigid contact lenses which provide a smooth surface in front of the cornea and give better vision.
Treatment:
Collagen Cross-linking (CXL) can slow or stop the progression of keratoconus. It is recommended for individuals with progressive Keratoconus or post-laser ectasia (cornea weakening) following laser vision correction, to stabilize the cornea.
Once progression and vision have been stabilised, Implantable Contact Lenses (ICL) can be used to permanently correct your vision and reduce dependence on spectacles or contact lenses. Laser Vision Correction is contraindicated if you have keratoconus.
