Christian’s Keratoconus Story – “ClearKone Changed the Way I See Life”

Thursday, June 23rd, 2011

My vision challenges began in junior high school when I started to wear glasses. Although my vision was fine at that time, things started to change when I entered high school. I began to notice that I wasn’t able to read the chalkboard. Even though I sat in the front row, I found it difficult and frustrating to read the teachers’ notes. I went back to my optometrist, who gave me another pair of glasses with a stronger prescription. Unfortunately, the new glasses only helped for a period of time. By the time I was in my junior year, my vision was a problem again. The new glasses no longer corrected my vision. I decided it was time to see a new optometrist. 

In my senior year of high school my new optometrist, Dr. Barry Leonard, diagnosed me with keratoconus. While I was glad to have found out the cause of my vision problems and learn that contact lenses could improve my eyesight, I could never have imagined the contradictions that came with contact lens wear. My doctor fit me in RGP lenses, which did improve my vision, but the lenses were so uncomfortable. My eyes were often irritated, so I would try to function without wearing the lenses. Unfortunately, my vision was so poor without them that I could not drive, see faces of friends at a distance, or read a book with small font. Keratoconus was truly affecting my daily activities!

Dr. Leonard then recommended that I try the ClearKone lens from SynergEyes. He explained that the rigid center would give me the visual acuity I needed, while the soft skirt would keep my eyes comfortable throughout the day. It sounded like a great option! As we began the fitting process, it was difficult for my lids to open wide enough for the lenses to be inserted. My eyes were so sensitive that my lids would close whenever the lens got near my eye. Thankfully, Dr. Leonard was very patient with me, and after many attempts, was able to insert the lenses.

Once I began wearing the lenses, I was amazed. My vision was clear and crisp, and the lenses were so comfortable that I could wear them all day long without irritation. It really was the best of both worlds!

I have now been wearing the lenses for several months, and my life has changed in so many ways. I can distinguish faces from a distance and see their expressions, which is so wonderful! I am also able to drive, use the computer, and read books with small font. I feel like I now have a normal life without the frustrations of poor vision. ClearKone lenses have truly changed the way I see life!

Recent Hybrid Lens Technology

Saturday, August 28th, 2010

By Rob Davis, O.D., F.A.A.O.

In 2001, Quarter Lambda Technologies (later to become SynergEyes, Inc.) began research and development of a new hybrid contact lens design that ultimately received FDA clearance in 2005. The SynergEyes® hybrid lens differed from the original SoftPerm® design in several key areas. SynergEyes hybrid contact lenses use high oxygen permeable materials and a patented technology called “Hyperbond®” that significantly reduces the separation between the rigid and soft junction of the lens that was common in the SoftPerm® lens. The soft skirt portion incorporates a special surface treatment called ‘HydrolEyes®’ to improve surface wettability and comfort.  In addition, the SynergEyes® lens is available with adjustable soft skirt curves as well as multiple fitting curves allowing for more customized fitting of the lens for virtually any patient in a contact lens practice.

SynergEyes initially developed four hybrid contact lens designs, including the SynergEyes® A lens for patients with astigmatism, the SynergEyes® KC lens for fitting cases of emerging keratoconus and other steep corneas, the SynergEyes® PS lens for fitting post-surgical corneas and other eyes that have flatter corneal surfaces; and the SynergEyes® Multifocal design for patients over 40 who cannot see close up.

In 2010, SynergEyes introduced the ClearKone® design, which fits a much broader range of keratoconus and irregular cornea patients then any other hybrid contact lens products.

The SynergEyes® family of hybrid lenses provides excellent comfort, optimal vision and corneal health. Numerous fitting parameters and the high oxygen permeability of the RGP material eliminates “tight lens syndrome” that can result in edema or swelling of the cornea. The increased amount of tears underneath the lens eliminates friction between the lens and the surface of the cornea giving an added measure of safety and comfort. The improved surface treatment reduces the dryness experienced by other contact lens designs. The improved durability of the rigid/soft junction, base curve availability, and options of skirt radii of the SynergEyes® lens has evolved this technology to the point that it has now entered the mainstream contact lens category for patients with normal corneas as well as irregular corneas.
