Computer-controlled
The IntraLase is a highly precise, computer-guided laser that delivers micron-level accuracy, much greater than the hand-held microkeratome blade. With the IntraLase laser, the surgeon is able to ensure a perfectly centered flap of predictable size, shape, and thickness.
Programmable
parameters
With IntraLase, the
doctor programs the dimensions of each flap, allowing
precise control of flap diameter, depth, hinge location,
beveled edges, centration, and overall architecture. Such control and precision are nearly impossible
with a hand-held blade.
By controlling the dimensions of the flap, the doctor
can ensure that the exposed corneal surface is properly
prepared for an optimal LASIK procedure.
Intrastromal
Procedure [Play

The IntraLase laser creates the flap from the inside
out (intrastromally), ending with the creation of the
outer seam at the surface of the eye. The outer surface
is breached ONLY after the surgeon has ensured proper
separation of the interior layer and centration of the
flap.
Maintaining the structural integrity of the epithelium
during the procedure also avoids unwanted movement.
This allows for greater precision and control while
the flap is being created.
Low-impact, low-level light energy
Using low-level light energy, the IntraLase delicately
dissects the corneal flap without any trauma to the
corneal tissue. This eliminates the risk of tearing,
stretching and abrasions associated with the physical
impact of the microkeratome when it cuts across the
eye.
Ability to resume interrupted procedure
Unlike the microkeratome, the IntraLase laser can be
stopped and started, at will, with no detrimental impact
on the corneal flap or visual result.
In comparison, a failed microkeratome procedure (or
partially cut flap) cannot be re-attempted until the
flap has completely healed. Subsequently, the LASIK
procedure is cancelled and the patient is sent home
for approximately 3 months (or more) before the surgeon
can re-attempt a LASIK procedure. During that time,
the partially cut flap may be susceptible to dislocation,
ingrowth and other various complications.
Real time view
Unlike the microkeratome procedure, the doctor has a
real-time view of the IntraLase procedure. As such,
the doctor can monitor progress and ensure proper centration
is maintained during the procedure.
Speed & Patient comfort [Play
procedure video]
The IntraLase procedure is quick (15-30 seconds), silent
and much gentler on the eye than the oscillating blade
of the noisy, hand-held mechanical microkeratome (blade).
IntraLase patients feel much more comfortable and reassured
in their choice to have LASIK. And, in a recent study,
patients showed a preference for the vision in their
IntraLase treated eye over the mechanical microkeratome
(blade) treated eye 3 to 1.1
