Wavefront Lasik
See our schematic QuickTime Lasik Movie
Background:
Wavefront technology has been used for years in the astrophysics
field of telescopes. In fact, this technology was what
was used to fix the Hubble Telescope about 10 years ago, when
the first images attained from the original telescope were
distorted. The distortions were caused by a chip of paint
on the null corrector, an instrument used to create the "perfect"
mirror. Because of this chip of paint, what was supposed
to have been a perfect mirror, ended up being a mirror that
was too flat at the edges. This induced significant higher
order aberrations, or distortions, in the Hubble Telescope
system. The astrophysics needed to create a way to compensate
for the distortions in order for the images to be perfect. They
needed the perfect "pair of glasses" for the Hubble Telescope. Wavefront
technology allowed them to create a compensating mirror and
finally attain perfect images of stars and galaxies.
This same high technology and concept is now being applied
to the human visual system through laser surgery.
Wavescan: a Wavefront Analyser:
The Wavescan is an instrument available at CLS and used to
measure and analyze the aberrations, or distortions, of an
eyeball. It is called a WAVEscan, because light is made
up of waves. The Wavescan sends perfect waves of light
through the visual system by projecting it directly onto the
retina, the very back of the eye. As the waves travel
out of the eye, the wavescan captures an exiting wave. Because
this wave went through an eye, this wave is now distorted and
represents the distortions and imperfections in that eye.
An analogy to the concept above is that of a wave on a lake. Once
a wave is created, you can see it undulate through the surface
of the lake. If it encounters a rock, the equivalent
of an imperfection in the eye, that wave pattern will be distorted
by that rock and waves past that rock will reflect that distortion.
Scientific calculations are used to analyze and interpret
these distortions and classify them into different "orders."
Why choose Wavefront Lasik:
In any optical system, there is an infinite amount of aberrations
and these are classified into different orders. Typically,
the first and second orders of aberration are correctable by glasses,
contact lenses and traditional Lasik.
Wavefront Lasik can potentially correct up to the sixth order of aberration, allowing for the best chance
for attaining the best quality of vision, with the least
amount of night glare and the least chance for an enhancement.
The reasons to choose Wavefront Lasik are:
- You are particular about your vision, have the need to
see very crisp, and would like the best chance of attaining
the best quality of vision possible at this time.
(FDA studies have shown that 70% of wavefront Lasik patients,
at the end of one year, were able to see 20/16 or better. 98%
of wavefront Lasik patients were able to see 20/20 or better. 100% of
wavefront Lasik patients were able to see 20/40 or better.
Results like these are what convinced us to offer this amazing
technology to our patients.
- You are concerned about night glare and would like the
best chance of reducing any night vision symptoms.
(Because Custom Wavefront corrects the unique imperfections
in each individual's vision, there is a potential that night
vision may be improved. 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.)
- You want the least chance for needing an enhancement after
your primary Laser surgery. The Wavescan measures your
prescription in 0.01 Diopter steps. (A Diopter is a
unit of measurement of our prescription.) The phoropter,
the instrument used to measure the prescription in exam rooms,
measures the prescription in 0.25 Diopter steps. The
Wavescan essentially measures the prescription 25 times more
accurately.
- You are a high-tech person and wish to have Laser surgery
with the highest technology.
Is Traditional Lasik not as effective as Wavefront Lasik?
Despite what some may advertise, Traditional Lasik is still
"custom" Lasik. However it is only customized
to your prescription.
Wavefront Lasik not only customizes the laser to your prescription,
but also customizes it to your entire visual system. For
the right candidate Traditional Lasik is great, and Wavefront
Lasik may be better, as it is a more customized.
Is Wavefront Lasik more risky since it is newly approved?
Wavefront Lasik is performed technically the same way as Traditional
Lasik. The surgeon will still create a flap, lift
it, treat the cornea with the laser, and replace the flap. The
main difference between the two is the laser pattern that is
placed on the surface of the eye. Wavefront Lasik's laser
pattern is more customized to your visual system than the Traditional
Lasik's laser pattern.
Wavefront Lasik may also be considered safer due to its potential
ability to decrease night vision problems and treat the prescription
more accurately.
Why does Wavefront Lasik cost more?
Wavefront Technology is an expensive technology. Much
more time and measurements are involved in the calculations
of the perfect treatment for your eye with Wavefront Lasik.
