ClearKone® Lenses for Keratoconus
|
Remember when you had only two choices in contact lenses? “Hard” (GP) lenses provided good vision, but were often irritating and uncomfortable. Soft lenses offered good comfort, but couldn’t correct your vision problems. ClearKone was a technological breakthrough that made having to compromise a thing of the past. ClearKone hybrid contact lenses offer all the benefits of gas permeable (GP) and soft contact lenses without any of the disadvantages for an overall GREAT contact lens experience.
Keratoconus is a progressive, debilitating
bilateral eye disease in which degenerative
thinning of the cornea results in complex irregular
bulging of the normally round, spherical cornea (the
clear covering in front of the eye). Keratoconus results
in grossly distorted vision similar to looking through a
windshield while driving in a rainstorm without using
windshield wipers.
Keratoconus is characterized by
thinning and protrusion of the central cornea, resulting
in a ghosting and glare, photophobia, halos around
lights, decreased vision, and monocular diplopia (double
vision). Those with keratoconus suffer from decreased
vision which cannot be corrected with spectacles or
conventional contact lenses. However, most keratoconus
patients can achieve functional vision with
designed therapeutic contact lenses. |

Keratoconus is one of the few conditions
where contact lenses are a medical necessity (other conditions include unilateral aphakia, post corneal transplant, and a very
high myopia).
It is well documented that
rigid gas permeable (RGP) contact lenses or a
combination of a rigid gas permeable lens riding
on a soft lens configuration are the treatment
of choice for keratoconus.
These uniquely
designed keratoconic lenses improve vision by
providing a clear optical lens that masks the
distorted areas of the cornea creating a smooth,
regular optical surface over the patient’s very
irregular, cone-shaped cornea. By masking the
distorted vision caused by keratoconus, these
lenses can provide the required visual acuity
necessary to perform daily routines. Without
these corrective lenses these patients are
visually handicapped. They would not be able to
perform even the simplest tasks of daily life:
read, drive a car, attend school or even
recognize a face across the room. |

Eyeglasses cannot achieve these results.
The lenses in a pair of glasses are too far away
from the optical surface of the cornea to create the
smooth refractive surface necessary to translate the
image clearly to the back of the eye and therefore
to the brain. These therapeutic contact lenses are
not cosmetic. They are designed devices
that treat a medical problem. Just as a leg brace
helps a lame patient to walk, these therapeutic
contact lenses provide treatment to allow those with
keratoconus to have clear vision. |

Lens Design |
-
ClearKone is a FDA-cleared hybrid contact lens specifically designed for the treatment of keratoconus and other corneal irregularities. This hybrid contact lens combines the best of both worlds – the crisp vision of a GP contact lens with the all-day comfort and convenience of a soft lens.
|
|
|
Why ClearKone?
|
-
ClearKone is specifically designed to help restore vision to patients with the many types and stages of keratoconus. The ClearKone GP lens vaults over the cornea, and the soft skirt offers all-day comfort.
|
|
|
Crisp Vision
|
-
The ClearKone lens has a rigid center that creates a smooth uniform surface allowing light to focus properly. The added benefit is that the GP lens is centered over the visual axis regardless of where the cone is located on the cornea or how large it is, thereby decreasing visual distortions and providing superior vision.
|
|
|
Comfortable
|
- The soft skirt of the ClearKone design is made from materials similar to soft lenses making the lens comfortable. The soft skirt design of ClearKone also prevents dirt from getting under the lens and will not pop out unexpectedly.
