Keratoconus: Basic Information and Diagnosis

What is Keratoconus?

Keratoconus is an abnormal condition in which the spherical, domed cornea (The clear, front-facing window of the eye) becomes thin, and emerges in the conical shape. This abnormal shape prevents the light from entering into the focusing properly on the retina and causing disorders in sight. The word keratoconus literally means cone-shaped cornea.

The cornea is an important part of your eye. The light enters through the cornea within the eye, which refracts this light, or focuses so that you can see clearly. During keratoconus, the shape of the cornea changes, which distorts your vision.

Disease Period

Many people with keratoconus suffer from only a moderate type of disease and can be easily treated with spectacles and/or soft contact lenses. However, some patients may need to use semi-soft or hard contact lenses permanently during their lifetime to see clearly. In severe cases, transplant of the cornea may be required.

Diagnosis and test

Keratoconus is determined during a regular eye examination. Slit lamps are used to determine serious cases of keratoconus, but many times corneal topography is required to determine the subtle or complex cases of keratoconus. To determine exact shape or type of your cornea some additional tests may be required. These checks are:

    Keratometry
    Computerized corneal mapping.
    Retinoscopy
    Distant Direct Ophthalmoscopy
