The IntraLase
Method uses tiny, rapid pulses of laser light
to create your corneal flap-instead of using a
metal blade-during the first step of LASIK. Each
pulse of light passes through the top layers of
your cornea and forms a microscopic bubble at
a specific depth and position within your eye
that is determined by the doctor. The IntraLase®
laser moves back and forth across your eye, creating
a uniform layer of bubbles just beneath your corneal
surface.
Just prior to applying laser vision correction,
the doctor creates your corneal flap by gently
separating the tissue where these bubbles have
formed. The corneal flap is then folded back so
the doctor can perform the second step of your
LASIK treatment. IntraLase refers to the exciting
new technology used to preform blade-free LASIK,
or intraLASIK. A femtosecond laser is used to
create a corneal flap at a pre-programmed depth
and position from the inside-out. First the eye
is fixated with a low-pressure soft suction ring.
This prevents the patient from moving the eye
in an unpredictable manner. Then the laser separates
the corneal tissue at the predetermined depth
forming bubbles of water and carbon dioxide at
that plane. In less than half a minute, the laser
has created enough bubbles to create a smooth
surface that will become the interface between
the flap and the corneal bed. Just prior to applying
laser vision correction, the doctor creates your
corneal flap by gently separating the tissue where
these bubbles have formed. The corneal flap is
then folded back so the doctor can perform the
second step of your LASIK treatment
The 3-micron laser spot size is able to create
a customized flap with pinpoint accuracy. The
amazing accuracy of this device has allowed many
individual who did not qualify for LASIK to now
become successful LASIK pateints! IntraLase achieves
this all without altering the corneal curvature
nor damaging any surrounding tissue.
With IntraLase, the risk of a flap complication
such as corneal abrasion, thin flap, thick flap,
partial flap, incorrect diameter, or buttonhole
flap becomes much less than that of a traditional
microkeratome. Additionally, the flap is shaped
differently from a microkeratome flap. Unlike
the one-dimension flap of a microkeratome, IntraLase
creates a flap of uniform thickness with veritical
edges. This "manhole cover" architecture helps
prevent additional complications such as flap
slippage or wrinkling if accidentally rubbed or
bumped when healing after surgery. IntraLase can
be used to treat almost any prescription with
a greater degree of accuracy and safety.
