What is Keratoconus?
Keratoconus is caused by a thinning of the front surface of the eye, the cornea. This thinning causes the cornea to rapidly change shape creating high degrees of astigmatism and distortion. People with this condition may need hard contact lenses to obtain clear vision, or may need a surgical procedure to stabilise their cornea.
This condition usually runs in families and it can occur in one or both eyes and often begins during a person’s teens or early 20s.
Some people with mild degree of this condition will only notice distorted vision in one or both eyes with their glasses, and prefer to wear soft contact lenses to correct the eye sight. Moderate or severe keratoconus, however, may require the fitting of RGP specialty contact lenses.
Special examination techniques, called corneal topography, can detect keratoconus often before the person notices any significant blur. Corneal topography involves mapping and analysing the surface of the cornea. We are one of a handful of optometry practices in the Central West that has this technology.
