Keratoconus

Keratoconus (literally, conical cornea) is a thinning of the central zone of the cornea, the front surface of the eye. The normal pressure within the eye makes the thinner area of the cornea bulge forward slightly.

Signs and Symptoms You May Have Keratoconus Include…

Blurred vision

Astigmatism

Indistinguishable from short sightedness

Why Should You Be Concerned?

01

Keratoconus is an inherited disorder that occurs in about one in 3 000 people. It is a recessive condition requiring genetic factors to be inherited from both parents, so the chances of the children of a person with keratoconus also having the condition are low (around one in 50).

02

Keratoconus usually becomes apparent between the ages of 10 and 25 years. It is sometimes associated with other conditions such as allergies, infantile eczema, asthma, reduced night vision, double jointedness and, in rare instances, with occasional short bouts of chest pain.

03

Because keratoconus is a genetic condition, it cannot be treated with drugs but glasses and contact lenses can give good vision and surgery can be used to treat severe cases. Keratoconus does not cause blindness.

04

Interestingly, about 60% of people with keratoconus go on to tertiary education, compared with 15 per cent of the population as a whole.

The Best Ways to Manage it

Contact Lenses

As keratoconus progresses, the shape of the cornea becomes irregular and it is not possible to correct the vision with spectacles alone. In such cases, rigid contact lenses can be used to provide good vision. The contact lenses essentially provide a new, regular front surface for the eye, eliminating the distortions caused by the keratoconus.

Corneal Topography

We have the latest equipment to diagnose and treat Keratoconus. Computerised corneal topography is a three-dimensional imaging process used to map the surface power of the cornea. The data points gathered are then digitised and analysed by sophisticated computer software. The result is a detailed map of the corneal curvature much like a topographical map of land.
