Understanding the Procedure
CustomVue™ Individualized Laser Vision Correction
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
How does the laser know what to correct in my eyes?
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
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
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.
the WaveScan® hurt?
No, the WaveScan is a measurement device that you simply gaze
into while it measures the vision imperfections in your eye.
is CustomVue™ laser vision correction?
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
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?
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?
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.
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
are some of the results of CustomVue™ to date?
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
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?
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.
