Keratoconus Exam

Keratoconus is a degenerative disorder of the eye which affects the cornea (the clear front surface of the eye) causing it to thin and change to a more conical shape, rather than the spherical shape of a normal eye.

Keratoconus can cause substantial distortion of vision and sensitivity to light .It is typically diagnosed in the person’s adolescent years. If both eyes are significantly affected, the deterioration in vision can affect the person’s ability to drive a car or read normal print.

In most cases special contact lenses can be fitted to allow the person to function normally. In order to fit these special contact lenses you need to have a corneal topographic map to determine the exact shape of the cornea.

Corneal topography is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, (the clear window on the front of the eye). It is totally painless and very quick and in our expert hands is over before you know it. At Evans & McMahon Eyecare Plus we have been using corneal topographers for over 20 years and our current Medmont e300 is one of the most accurate machines in the world.
