What you need to know about Keratoconus

Often the cause of keratoconus is unknown. Some studies have found that keratoconus runs in families, and that it happens more often in people with certain medical conditions. But most often, there is no eye injury or disease that could explain why the eye starts to change. Keratoconus usually begins in the teenage years, but it can also start in childhood or up to about age 30. The changes in the shape of the cornea occur slowly, usually over several years.

Because fitting a gas permeable contact lens over a cone-shaped cornea can sometimes be uncomfortable for a person with keratoconus, some eye care practitioners advocate “piggybacking” two different types of contact lenses on the same eye.

These things might be related to keratoconus, but your doctor must measure the curvature of the cornea to be certain. Several different instruments can be used to measure the curvature of the cornea. One instrument, called a keratometer, shines a pattern of light onto the cornea. The shape of the reflection of the pattern tells the doctor how the eye is curved. There are also computerized instruments that make three-dimensional “maps” of the cornea, a process called corneal topography.

Hybrid contact lenses work on a similar principal as RGP’s. This style of contact lens has a rigid gas permeable center that is fused to a soft contact lens “skirt” and therefore a hybrid of hard and soft contact lenses. By fusing the two styles of contact lenses the visual benefit of a RGP is combined with the comfort of a soft lens. As with the traditional RGP, these lenses must be specially fitted to ensure function, comfort, and safety.

One example of a scleral lens is the Boston Scleral Lens Prosthetic Device (BSLPD). This cone-shaped device resembles a large contact lens and works partly by maintaining a “pool” of fluid on the eye’s surface through which light rays pass and are bent to achieve proper focus.
