Keratoconus Guide


One of the most common misconceptions about vision health is that eye disorders don’t develop until you are older. While many, such as cataracts and glaucoma, are more common as you age, some – like Keratoconus – usually develop when you are in your twenties or thirties. If you’ve been diagnosed with Keratoconus, you can find information about this problem in this guide.

Keratoconus means cone-shaped, which makes sense based on what happens to the eye as a result of the condition. As you know, the eye contains several parts. One part is the cornea. This is a thin layer, which covers the iris (the colored part of the eye) and the pupil. The cornea plays a very important role in vision. What we know as “seeing” is actually the process of light entering the eye and being translated into images by the brain. The cornea, as well as the lens, refract that light and therefore influence what we end up “seeing.” If the cornea can’t do its job properly, what we “see” may end up being skewed and distorted.

With Keratoconus, the cornea, which is normally shaped like a dome, begins to get thinner and to become cone-shaped. This change in shape means the light can’t come into the eye in the same way and that causes a vision problem known as astigmatism, a problem in which the curve of the cornea is not symmetrical.
