Keratoconus is a condition where the cornea (the transparent layer of the iris) is shaped like a cone instead of a dome. The vision becomes distorted due to the way the light is refracted in the cornea. It usually develops in younger people between 16 – 30.  It can be caused by rubbing your eyes vigorously, some allergic conditions, and genetics.

Symptoms & Diagnosis

Your Ophthalmologist will examine your cornea to diagnose the condition.

  • Distorted or blurry vision blurred or distorted vision
  • Sensitivity to light
  • Frequent change in spectacle prescriptions
  • Flaring and halos around lights
Keratoconus Example


There is a variety of treatments available depending on the severity of the condition.  Soft contact lenses are used to treat Keratoconus in the early stages. Hard contact lenses are used if the condition has progressed further and help to stabilise the shape of the cornea. Day surgery is needed for severe cases and can include a corneal transplant.
