Corneal Collagen Cross-linking for Keratoconus and Corneal Ectasia Patients
 Advertisement Information
Foundation participating in first U.S. study of collagen cross-linking (CXL) to assess safety
and effectiveness. A new clinical research investigation
has begun to study the benefi ts of corneal
collagen cross-linking (CXL) in subjects
with progressive keratoconus or corneal
ectasia after prior refractive surgery.
These studies are the fi rst in the U.S. of
CXL and are designed to assess the safety
and effectiveness of CXL for slowing the
progression of both of these conditions.
Corneal collagen cross-linking is a
procedure that involves administering
ribofl avin and UVA in carefully selected
parameters that strengthen the front layers
of the cornea (clear covering of the eye) and
avoid damage to the back part of the eye.
The ribofl avin and UVA light source that
is used for CXL are both investigational in
the United States and are not yet approved
by FDA.
If you qualify and decide to participate
in the study, you will receive the ribofl avin
and UVA light at no cost. However, there
is a fee for the consultation and surgery.
Because of the investigative nature of the
procedure, most insurance companies
will not cover the surgery and you will be
required to pay this fee up-front before the
procedure is performed.
If you, or someone you know, may be
interested in participating in this CXL
study, please contact Kathy Kelley, O.D. to
learn more about the study or to schedule
a consultation examination to see if you
qualify for the study. She may be reached

- Vision with contact lenses or glasses is
worse than 20/20
- Corneal thickness greater than 300
microns at the thinnest point
- If you are female, you cannot be
pregnant
- Can leave your contact lens out for
at least 3 months in the eye to be
treated
- If you have keratoconus, you cannot
