What is Keratoconus?

Keratoconus is a condition in which the normally round, dome-like cornea (the clear front window of the eye) becomes thin and develops a cone-like bulge. Keratoconus literally means “cone-shaped cornea”. Such a cornea can distort your vision and can make daily activities difficult.

The diagnosis is confirmed by performing a topography map (elevation map) of the cornea. If keratoconus progresses, it may cause such severe shape abnormality that a corneal graft may be required.


In the early stages, the condition can be managed with spectacles. As the shape change occurs spectacles may no longer be very effective. Good quality vision can then be achieved by hard contact lens.
The current aim of treatment in keratoconus is to try and halt the progression of the cone formation. Therefore reducing the need for grafting. In the past few years Corneal Crosslinking has become a very effective way of halting this progression
