ClearKone Hybrid Contact Lens
ClearKone is a prescription hybrid contact lens introduced in May 2009 by SynergEyes, Inc.
A hybrid contact lens is a lens composed of a rigid gas permeable lens in the center that is
surrounded by a soft contact lens.
SynergEyes, Inc. (Carlsbad, CA), the manufacturer of the only FDA-cleared hybrid contact
lenses specifically designed for keratoconus, has previously released four hybrid lens
designs; “A” for standard corneas, the “KC” lens for keratoconus, “PS” for post-surgical eyes,
and a multifocal lens, “M”, for presbyopic patients. Similar to the KC lens, ClearKone was
released specifically for patients with keratoconus. Moreover, ClearKone is designed to fit
a broader range of patients diagnosed with moderate to advanced keratoconus.
Corneal collagen crosslinking (CXL) is a procedure that involves administering riboflavin
and ultraviolet light (UVA) to strengthen the anterior layers of the cornea. CXL has been
proposed as an effective method of halting or reducing progression of keratoconus and
corneal ectasia. Intacs are intracorneal ring segments implanted into the cornea and make
the corneal optical surface smoother. These two surgical procedures may aid non-surgical
treatment options such as utilizing a contact lens to further improve vision.
Studies have reported increased lens tolerability in irregular cornea patients fitted with
hybrid contact lenses with over 85% success rate. In those cases, best corrected visual
acuities typically improve while wearing hybrid lenses when compared to rigid gas
permeable (RGP) lenses. As a result, patients often report subjective improvement in their
quality of life.
ClearKone hybrid contact lens may further improve vision for patients with keratoconus or
corneal ectasia who have subsequently had CXL or CXL combined with Intacs surgical
procedure(s). Currently, there exists limited data regarding ClearKone’s performance in
this population.
Here at the CLEI Center for Keratoconus, we have treated approximately 90 patients with
CXL in a clinical trial over the past two years and have been working with Intacs for
keratoconus for several years. Our data analysis and research with Intacs over the years
have let us develop enhancements to the procedure such as creating Intacs tunnel
geometries and the use of different Intacs sizes. We have been fitting SynergEyes hybrid
lenses for numerous years and the ClearKone contact lenses since its release.
NEW STUDY OF CLEARKONE LENS ON PATIENTS WHO HAVE RECEIVED CORNEAL
COLLAGEN CROSSLINKING OR COMBINATION CORNEAL COLLAGEN CROSSLINKING
AND INTACS:
We are pleased to announce that we are currently enrolling patients in a
study evaluating the performance of ClearKone contact lens on patients with keratoconus
or corneal ectasia who have received either 1) corneal collagen crosslinking (CXL), or 2)
combined CXL and Intacs surgical procedure(s). The study is being conducted to determine
the effectiveness of SynergEyes ClearKone hybrid contact lens in improving corrected
visual acuity. As well, this study will assess any improvements in corneal optics as a result
of wearing these lenses.
