Wavefront Lasik measurement system is an upgradation over
traditional Lasik surgery, contact lenses or eyeglasses. Some
irregularities associated with eye’s optical system, which were
impossible until the advent of wavefront related technology used in
custom lasik, can now be achieved. Almost 90% or more of these
refractive errors, such as nearsightedness, farsightedness and
astigmatism, can be treated by optical devices, like glasses and
contact lenses, or by Laser Eye Surgery, using the usual methods of
LASIK, PRK or LASEK. The remaining 10% of optical aberrations create
images which are distorted by chromatic irregularity, spherical
aberration, diffraction, curvature of field, coma, trefoils and
quadrafoils. These irregularities are collectively known as "higher
order aberrations." Wavefront Lasik is the best treatment option to
create a completely customized reshaping of the surface of the
cornea in higher order aberrations..
Many patients nowadays do not realize that the eye is an imperfect
optical system. As light rays pass through the individual optical
components of the eye, they are subject to being twisted by the flaw
found in the cornea and the crystalline lens. In order to achieve a
normal corneal re-shaping, the higher order optical aberrations are
measured with the help of Wavefront lasik system, as this technology
can diagnose and measure aberrations that no other system can even
see. It is important to understand that without a Wavefront Lasik
diagnosis, it is impossible for a doctor to accurately determine
which surgical method is worth considering for a patient.
Requirements:
• You need to be qualified under Food and Drug Administration (FDA)
guidelines before Wavefront LASIK would be considered for your eye
condition.
• You might be considered a candidate for Wavefront Lasik if you
have mild or moderately high degrees of common problems such as
myopia, hyperopia, and astigmatism..
The procedure:
During a Wavefront Lasik diagnosis, light is sent into the eye in a
specific pattern. The waves are measured, once the light has passed
the visual system. A square grid going in and a wavy grid coming
out, represent aberrations.
With Wavefront Lasik, your eye's ability to focus light rays is
measured, and a 3-D map is created that displays abnormalities in
the way your eye processes images. This information guides the laser
in customizing the treatment to reshape your eye's corneal surface
so that these irregularities can be corrected.
Benefits:
Wavefront Lasik has-
• Reduced the risk of post-LASIK complications, such as glare,
nimbus, and difficulty with night vision disturbances
• Increased the chance of achieving 20/20 vision or even better
• Reduced the chance of losing best-corrected vision
• Reduced the chance of losing visual quality or contrast
sensitivity
Wavefront Lasik technology is pioneering because it has the
prospective to improve not only how much you can see, but also how
well you can see. This has immensely benefited the patients in terms
of contrast sensitivity and fine detail.
