Custom Wavefront is a state-of-the-art advancement in LASIK surgery, providing patients with an even greater level of safety and accuracy than ever before. This technology detects distortions in the optical system to eliminate post-surgery visual side effects such as streaks and halos around lights. It also provides for advanced eye tracking control, resulting in effective, accurate correction of astigmatism with laser surgery.
Dr. Cavanaugh: Custom wavefront treatment is really the state of the art.
And what we do with that is we take each person
individually, scan the eyes with an aberrometer which detects
distortions in the optical system that we never knew existed before. These
are the things that cause people to have streaks and halos
around lights and eyes and the distortion or the
noise or junk in the optical system.
The standard Lasik, it treats the patient just like the
glasses or contacts. It corrects the prescription but
it doesn't do anything about those aberrations or
those other distortions. So this is really a step beyond. It has a
tremendous eye tracker that some of the other lasers
Something called advanced control eye tracking which
allows us to accurately correct astigmatism. And I
don't know how many times I've heard where patients say,
'I'm not a candidate for Lasik because I have astigmatism.' And that's not
true anymore. With this, it uses active radar to lock onto the
surface of the eye, it locks on to the center of the
pupil and if the patient moves their eye whatsoever it tracks
in all directions. Left, right, up, down, and rotation. And rotation is
really key for astigmatism correct.
At the scanner we sense the location of the eye and then
the laser we sense it again. We can make adjustments with
the laser to follow and track that treatment the entire
time. So the level of safety and accuracy is unheralded in what we've
ever seen before and it's been a tremendous advance for our
