What is keratoconus?

Keratoconus is a disorder of the anterior surface of the eye (the
cornea). In simple terms keratoconus causes the bulging of the cornea
from its normal round shape to a cone shape. This interferes with a
person’s vision and can severely affect the way they see the world
making simple tasks like reading, watching TV or driving very difficult.
The distortion caused by keratoconus has been compared to viewing a
street sign through your car windscreen during a driving rainstorm. The
progression of keratoconus is unpredictable. While keratoconus
interferes with the clarity of a person’s sight it rarely causes
blindness. In its early stages, keratoconus causes slight blurring and
distortion of vision and increased sensitivity to glare and light.

What causes Keratoconus?

The characteristics of keratoconus have been known for at least 200
years, but the specific causes are still undetermined. Several
theories have been proposed. One scientific theory is that keratoconus
is genetic in origin. About 7% of patients have other family members
with the disease. Another view holds that keratoconus represents a
degenerative condition. A third theory suggest that keratoconus is
secondary to some disease process. There is even a hypothesis that
keratoconus may involve the endocrine system. While there are many
theories, research into keratoconus continues.

How is Keratoconus treated?

As keratoconus advances, rigid gas permeable (RGP) contact lenses are
the first choice to correct vision adequately. Most of the time, this
is a permanent remedy. Because of the progression of the disease, it is
important that lenses are fitted with great care and are reassessed at
least annually by eye care professionals. The Rose K^(TM) lens is
internationally recognized as the leading lens for keratoconus. Its
complex geometry takes into account the conical shape in the cornea for
all stages of the condition. As a result the entire lens fits better
over the eye. For most patients this means better comfort and optimum
visual acuity.

    is this the surgery you are looking at?

    rigid gas permeable (RGP) contact lenses or The Rose K (TM) lens are the prefered surgical alternatives. There is also the Intacs which are inserted under the cornea to flatten it.
