CustomVue™ Individualized Laser Vision Correction - FAQ
WaveScan Technology
Philadelphia, Pennsylvania
Understanding the Procedure
What is laser vision correction?
Laser vision correction is a procedure that improves vision
by permanently changing the shape of the cornea (the clear
covering of the front of the eye) with a laser. Often referred
to as LASIK (an acronym for the medical term laser assisted
in-situ keratomileusis), it is the most commonly performed
type of laser procedure and an effective treatment for a
wide range of vision problems.
What is a laser?
A laser is a technology that utilizes ultraviolet light to
precisely reshape the inner layers
of the cornea. This reshaping is capable of correcting nearsighted
and astigmatism
conditions using the CustomVue procedure. How does the laser know what to correct in my eyes?
Laser vision correction is based on precise measurements
of the imperfections in your vision. These measurements
are taken with a powerful measurement tool known as the
WaveScan®. The WaveScan information is transferred
to the laser to guide the treatment.
What is a WaveScan® and a WavePrint® Map?
WaveScan technology provides a measurement and a visual representation
of your vision based on the behavior of light waves. It
compares light passing through your eye to the same light
pattern from an eye that needs no vision correction. The
WavePrint Map is the output of the WaveScan, it captures
the unique imperfections of a person’s visual path. How accurate is WaveScan technology?
WaveScan technology identifies and measures imperfections
in an individual’s vision 25 times more precisely
than standard methods used for glasses and contact lenses. Does the WaveScan® hurt?
No, the WaveScan is a measurement device that you simply
gaze into while it measures the vision imperfections in
your eye. What is CustomVue™ laser vision
correction?
VISX CustomVue™ is an individualized laser vision correction
treatment that is WaveScan-guided. This enables a doctor
to measure and correct unique imperfections in each individual’s
vision that could never be measured before with standard
methods used for glasses and contact lenses. With the CustomVue
procedure, nearsighted and astigmatic individuals have the
potential to achieve a new level of vision that we call Personal
Best Vision. What do you mean by Personal Best Vision?
Personal Best Vision refers to the new level of laser vision
correction that can be achieved with the CustomVue procedure.
Since WaveScan technology can measure and correct imperfections
that are unique to each individual’s vision with
25 times more precision than standard measurements for
glasses and contact lenses, individuals can potentially
achieve the best possible vision for their eyes.
How does the CustomVue procedure work?
First, the WaveScan technology measures the imperfections
in the eyes and produces a WavePrint® Map. Much like
a fingerprint, no two WavePrint maps are alike. Then, the
treatment information is transferred to the VISX STAR S4™ laser.
The doctor then uses that information to fine-tune the
procedure thereby providing a new level of precision and
accuracy. What can the CustomVue procedure do for me?
As shown in the clinical study, CustomVue has the potential
to produce better vision than is possible with glasses
and contact lenses. It tailors a distinct correction for
each individual–in fact each treatment is “designed” by
the unique characteristics of your individual eye. Results
Is the CustomVue procedure FDA approved?
Based on the clinical study, the U.S. FDA has approved the
CustomVue procedure as safe and effective for treating nearsightedness
and astigmatism. What are some of the results of CustomVue™ to
date?
In the FDA study, one year after the VISX CustomVue™ procedure:
- 100% of participants could pass a driving test without
glasses or contact lenses
- 98% of participants could see 20/20 or better without
glasses or contact lenses
- 70% of participants could see better than 20/20 without
glasses or contact lenses
In addition, many participants reported that they
had clearer, better vision both during the day
and at night,
compared
to their vision with glasses or contact lenses
before the procedure. What does better than 20/20 mean?
20/20 is the current standard for excellence in vision. But,
as shown in a clinical study, individuals with the CustomVue
procedure have the potential to see even better than 20/20.
In fact, one year after the CustomVue procedure nearly
70 percent of clinical study participants saw 20/16 or
better. Can the CustomVue procedure improve my night vision?
Yes, potentially. In the clinical study, four times as many
people were very satisfied with their vision
at night after the procedure as compared to their night vision
before the procedure with glasses and contact lenses. Getting All the Facts
Is there any way I can see what the results might be like
before the procedure?
Yes, with a PreVue® Lens, which approximates what your
vision could be like after the procedure. What is the PreVue Lens and would I need it?
The PreVue Lens is not a requirement for the CustomVue procedure.
Your doctor will decide if this tool is right for you.
Once the WaveScan® measurements are taken, the doctor
places a plastic lens under the laser. The individual’s
unique correction is created on the lens. The lens is then
fitted in a frame for viewing, so you can “preview” an
approximation of the potential result after a CustomVue
correction. How can I get more information about CustomVue?
