| What is VISX CustomVue? |
| VISX CustomVue individualized laser vision correction is
WaveScan®-driven, which, enables the physician to measure
and correct unique imperfections in each individual's vision.
Many of these imperfections could never be measured before
using standard methods for glasses and contact lenses. |
| |
| Who is a candidate for VISX CustomVue procedure? |
| If you are 21 years of age or older and wear glasses or
contacts to correct nearsightedness and/or astigmatism you
may benefit from CustomVue™. If you meet the criteria,
you should see your eye doctor for more information. |
| |
| What is Personal Best Vision? |
| Because every individual's eyes are unique, each individual
may benefit from a correction custom-tailored for them. For
the first time, CustomVue using WaveScan technology can measure
and correct the unique characteristics of each individual's
vision, potentially providing them with the best possible
vision for their eyes, or their Personal Best Vision. |
| |
| What is WaveScan® technology? |
| WaveScan technology was originally developed for use in
high-powered telescopes to reduce distortions when viewing
distant objects in space. This technology has now been applied
to laser vision correction, measuring imperfections in the
eye never before measured using standard methods for glasses
and contact lenses. WaveScan-based digital technology identifies
and measures imperfections in an individual's eye 25 times
more precisely than standard methods. Physicians use this
information to treat individuals with the CustomVue™ procedure. |
| |
| Why is WaveScan technology so important to the CustomVue
procedure? |
| Until now, physicians were forced to practice one-size-fits-all
vision. An off-the-shelf lens corrects an individual's vision
fairly well, but it does not correct it precisely because
it is not uniquely tailored to that person's fingerprint
of vision. Now, with WaveScan technology, we can custom tailor
a correction for the unique characteristics of each individual's
vision. |
| |
| How is the information transferred from the WaveScan to
the laser? |
| The WaveScan digital information is transferred to the
laser, providing a new level of precision and accuracy. |
| |
| What will a patient experience during the course of this
procedure? |
The individual will initially meet with the physician for
an evaluation to determine if he or she is a good candidate
for the CustomVue procedure. A WaveScan measurement will
be taken to map the unique characteristics of his or her
vision. The physician will assess several criteria including
level of correction, and overall eye health and discuss the
benefits and risks of the procedure with the patient. Once
it is confirmed that the individual is a good candidate,
he or she can be scheduled for CustomVue. The physician will
provide details for the individual on how to prepare for
the day of the procedure.
If the physician feels it is beneficial, he may choose to provide the patient
with a PreVue® Lens during the consultation. The PreVue Lens allows an individual
to "preview" their potential vision before the CustomVue procedure. The physician
will place a plastic lens under the laser. Using the information from the WaveScan,
the individual's unique correction will be placed on the lens. The lens is then
fitted in a trial frame for viewing. If a PreVue Lens is used in this evaluation,
your vision through the PreVue lens is not meant to be predictive of the end
result that you might achieve.
On procedure day, the individual will be seated in a reclined position. Anesthetic
drops will be placed in the eyes and a flap will be created in the cornea. The
individual's treatment information is transferred from the WaveScan to the VISX® laser
in order to drive the CustomVue procedure. The actual laser procedure typically
takes several seconds. The majority of individuals feel no pain during the procedure.
After CustomVue, individuals will notice results immediately, and vision will
continue to improve over the next few days. The individual will be scheduled
for a follow-up visit the next day, and again several weeks after the initial
procedure. |
| |
| Will I need glasses or contacts after
the CustomVue™ procedure? |
| Probably not. Six months after the clinical study, all
participants saw well enough to drive a car without glasses
or contacts. Ninety-four percent had 20/20 vision. However,
individual results may vary. |
| |
| What were the visual acuity results of the FDA clinical
study? |
A significant result was that six months after the VISX
CustomVue™ procedure:
* 100% of participants could pass a driving test without
glasses or contacts
* 94% of participants could see 20/20 or better without glasses
or contacts
* 74% of participants could see better than 20/20 without
glasses or contacts |
| |
| What does better than 20/20 mean? |
| 20/20 is the current standard for excellence in vision.
But, with the CustomVue™ procedure, individuals have
the potential to see even better than 20/20. In fact, six
months after the CustomVue procedure more than 74% percent
of clinical study participants saw 20/16 or better. |
| |
| How could the CustomVue™ procedure
affect my night vision? |
Many patients found their night vision was improved after
the CustomVue procedure. In fact, in the clinical study,
four times as many participants were very satisfied with
their night vision after the procedure as compared to their
night vision before with glasses or contacts.
