About ClearKone®

What is ClearKone®?

Remember when you had only two choices in contact lenses? “Hard” (RGP) lenses provided good vision, but were often irritating and uncomfortable. Soft lenses offered good comfort, but couldn’t correct your vision problems. Now, a technological breakthrough makes having to compromise a thing of the past.  ClearKone® hybrid contact lenses offer all the benefits of rigid gas permeable (RGP) and soft contact lenses without any of the disadvantages for an overall GREAT contact lens experience.

ClearKone® is an FDA-cleared hybrid contact lens specifically designed for the treatment of keratoconus and other corneal irregularities.  Using a revolutionary technology, ClearKone® combines the best of both worlds – the crisp vision of a high-oxygen rigid RGP contact lens with the all-day comfort and convenience of a soft lens.

ClearKone® is specifically designed to restore vision to patients with the many types and stages of keratoconus.  Because the ClearKone® lens vaults over the cornea, there’s minimal risk of corneal scarring, making ClearKone® hybrid contact lenses a healthy treatment option for keratoconus.  In addition, the soft skirt of the ClearKone® design helps to center the contact lens 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.  The ClearKone® design also prevents dirt from getting under the lens and will not pop out unexpectedly.  No other contact lens available today can provide all of these benefits in a single product.

How does ClearKone®  work?

The surface of an irregular cornea is just that – irregular. The “peaks and valleys” of an irregular cornea pose a special challenge when it comes to vision correction options. Contact lenses with a rigid surface are the undisputed gold standard for restoring vision to irregular cornea patients. A rigid surface over an irregular cornea mimics a spherical (normal) eye, allowing the light to focus properly on the eye to provide clear vision.

The ClearKone®  lens has a rigid center that creates a smooth uniform surface. The way the lens vaults over the cornea allows a layer of tears to form between the back surface of the rigid center and the eye. The tear layer fills in the “peaks and valleys” allowing light to focus properly to provide crisp, clear vision.  The ClearKone® fitting approach called “vaulting” allows doctors to simply increase the depth of the contact lens over the cornea depending on how steep or severe the individual patient’s keartoconus is.  The ClearKone® vault system comes in 11 different choices and therefore can accommodate even the most severe forms of keratoconus.  Your doctor will choose a vault that just clears your cone so the RGP portion of ClearKone® does not bear on the surface of your cone, virtually eliminating the chances of corneal scarring.

An important element of the ClearKone® design is the soft skirt.   Not only does the soft skirt provide exceptional all-day comfort and prevents dirt from getting under the lens, it also contributes to the excellent vision achievable in ClearKone®.  RGP lenses alone can move around on the eye, often “centering” on the steepest part of the cornea where the cone is located which is generally not in alignment with the visual axis of the patient.  This decentering of the RGP contact lens off of the visual axis results in distorted vision, halos and glare and less than optimal visual acuity for the patient.  Because the ClearKone® lens has a soft skirt, the optical center of the contact lens is held in place centered on the eye and most importantly in line with the visual axis of the patient.  This is why patients often report much better visual acuity in the ClearKone® lens and a marked improvement in the quality of the vision they can achieve in ClearKone®.

The unique design of the ClearKone® lens combines the best features of other contact lens designs into a single lens, while eliminating many of the issues that each individual lens can pose.
