Wavefront-Optimized Lasik
Wavefront-optimized Lasik is
a standard Lasik procedure performed using Wavelight's
Allegretto Wave Eye-Q laser, which is four times faster than
conventional excimer lasers. It is also based on phoropter
refraction. This new Eye-Q laser has been found to
reduce the complications such as glare,
halos, and other night vision problems which can
happen with conventional Lasik treatments.
Wavelight's claims that its
Wavefront-optimized ablations could preserve the natural
aspheric shape of the cornea much better compared to
standard Lasik. This procedure is currently approved by FDA
for treating the following refractive errors:
-
Up to -12.00 D of myopia
(nearsightedness), with up to -6.00 D of astigmatism
-
Up to +6.00 D of
hyperopia (farsightedness), with up to +5.00 D of
astigmatism
Wavefront-Guided
Lasik (Custom Lasik) vs. Wavefront-Optimized Lasik
While Wavefront-Guided Lasik
may benefit some patients, results from new study done by
FDA show that there are no significant difference between
the outcomes of treatment performed using Wavefront-Guided Lasik and
Wavefront-Optimized Lasik.
The study was designed to
directly compare the two approaches using the Allegretto
laser. Results show that Wavefront-Optimized Lasik gives
excellent result in correcting spherical aberration, without
affecting the higher order aberrations.
