LASIK in New York City is a popular elective vision
care procedure that can possibly reduce your dependence on glasses and
contact lenses. For many patients, Dr. Moadel feels that CustomVue technology
(also referred to as Wavescan technology) offers his patients the best
option for a safe and excellent visual outcome. Wavefront Technology
is also commonly called Custom LASIK eye surgery. Essentially, wavefront
technology involves taking a "digitized" image of the patient's
eye including the corneal contour. These measurements are made at a
computer station known as the wavescan. A wavescan image is analogous
to taking a digital photograph of the eye. These digital images are
then transferred to the laser where a unique treatment can be created
tailored to the patient's eye shape.
How Does Wavefront Technology Work?
Light from the wave scanning machine is projected into the eye on wavefront
sheets. These wavefront sheets enter the eye, pass through the entire
optical system and are then reflected back. The information obtained
in these wavefront measurements will be utilized by the ophthalmologist
to develop a more custom version of LASIK eye surgery. Once this wavefront
information has been collected the next step is to use this information
with the excimer laser to correct the higher-order visual aberrations.
The LASIK surgeon can then determine what adjustments should be made
to the corneal surface to produce a clear, crisp image for the unique
individual needs of each patient. The use of wavefront technology to
provide a more precise laser vision correction is known as, "Custom
LASIK" or "Wavefront-Driven LASIK". Early data suggests
that the 5-10 percent of patients who demonstrate higher-order aberrations
are the patients that will significantly benefit from Custom LASIK treatments.
Other patients may benefit from Custom LASIK to a smaller degree.
