Wavefront-guided LASIK is being hailed as the
greatest advance in laser vision correction because
of its potential to help individuals see even
better than 20/20.
Wavefront technology was originally developed
for use in high-powered telescopes to reduce distortions
when viewing distant objects in space. Its adaptation
to laser vision correction incorporated detailed
measuring of imperfections in the eye.
Conventional laser vision correction before Wavefront
corrected spherical and cylindrical errors, known
as lower order aberrations. This precision was
limited to 0.25 diopter steps. Wavefront uses
a sophisticated diagnostic test called the Wave
Scan which measures up to the hundredths of a
diopter. Additionally, the Wave Scan's "waveprint"
takes into account a series of higher-order aberrations
which provide extremely detailed information about
the entire visual system.
All of the WaveScan data - which is contained
in a report called the WavePrint - can be transferred
to the VISX Star S4 laser for Custom Wavefront-guided
LASIK to provide a new level of accuracy and precision.
Prior to FDA approval, clinical studies were
conducted. More than 90 percent of the study participants
undergoing wavefront LASIK could see 20/20 or
better; 74% could see 20/16 or better, and 27%
could see 20/15 or better. Also, nearly 70 percent
had either the same or better post-op vision than
their best visual acuity with glasses or contacts.
Additionally, four times as many participants
were very satisfied with their night vision compared
to night vision with glasses or contacts.
Because wavefront-guided LASIK utilizes the same
surgical process as traditional LASIK, you can
be reassured that more than several million LASIK
procedures have been successfully performed.
Your Today's Vision doctor in conjunction with
the surgeon will determine if you may benefit
from Wavefront-guided LASIK.
