VISX CustomVue™ Laser Vision
Procedure
Q: What is VISX CustomVue (individualized laser vision) correction?
A: 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.
Q: Who is a candidate for VISX CustomVue procedure?
A: 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.
Q: What is Personal Best Vision?
A: 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.
Measure and Correct
Q: What is WaveScan® technology?
A: 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.
Q: Why is WaveScan technology so important to the CustomVue
procedure?
A: 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.
Q: How is the information transferred from the WaveScan to
the laser?
A: The WaveScan digital information is transferred to the laser,
providing a new level of precision and accuracy.
Q: Can you briefly explain what a patient will experience during
the course of this procedure?
A: 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.
Beyond Glasses and Contacts
Q: Will I need glasses or contacts after the CustomVue™ procedure?
A: 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.
Clinical Study Results
Q: How many sites were included in the FDA clinical study
and where are they?
A: Six sites participated in the FDA clinical study at the following locations:
Bascom-Palmer
Eye Institute, Miami, FL |
William Culbertson, MD |
Baylor
College of Medicine, Houston, TX |
Douglas Koch, MD |
Coleman
Vision, Albuquerque, NM |
Stephen Coleman, MD |
Kraff
Eye Institute, Chicago, IL |
Colman Kraff, MD |
Maloney
Vision Institute, Los Angeles, CA |
Robert Maloney, MD |
Wilmer
Eye Institute, Baltimore, MD |
Terrence O'Brien, Nada Jabbur, MD |
Q: What were the visual acuity results of the FDA clinical
study?
A: 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 |
Q: What does better than 20/20 mean?
A: 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.
Q: How could the CustomVue™ procedure
affect my night vision?
A: 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.
WaveScan®-driven Procedure/PreVue® Lens
Q: Why is WaveScan technology so important to the CustomVue™ procedure?
A: For the first time, WaveScan technology captures unique
imperfections in each individual's vision that could not have
been measured before using standard methods for glasses and
contact lenses. This new level of measurement provides 25-times
more precision than standard measurements for glasses and contact
lenses. Then, WaveScan technology produces a detailed map of
the eye - much like a fingerprint, no two are alike. And, WaveScan
digital information is transferred to the laser, providing
a new level of precision and accuracy.
Q: What is the PreVue Lens?
A: The PreVue Lens allows individuals to test drive their potential
new vision before undergoing the procedure. Once the WaveScan
measurement is taken, the physician will place a plastic
lens under the VISX® laser. The individual's unique correction
will be placed on the lens, then the lens will be fitted
in a trial frame for viewing. The PreVue Lens is not a requirement
for the CustomVue procedure. Your physician will decide if
this tool is beneficial for each individual. 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.Please review the important information
