PerfectPulse Technology™
PerfectPulse
Technology™ represents a new approach to laser vision correction
- it accounts for speed, precision, and safety in the ALLEGRETTO
WAVE laser and offers improvements that are revolutionary in the
field. Smart energy control measures and adjusts
energy levels in the laser pulse from creation to delivery. High-speed
eye tracking charts the eye’s movement 200 times per second.
As a result, every laser pulse is completely controlled and accurate,
achieving the most accurate level of correction possible.
Smart
Energy Control
You can have peace of mind that the amount of energy in the laser
has been calibrated to exactly the right level. After the beam has
been created, it passes through three checkpoints on its way to
your eye. At each of these points, the energy level is checked and
adjusted if necessary, ensuring that the beam is perfectly attuned
at its destination.
ALLEGRETTO WAVE's laser
is essentially a precise, controlled beam of energy. The laser employs
a proprietary overlapping method to ensure accurate laser placement,
and is one of the ways that ALLEGRETTO WAVE achieves a rounder,
more natural corneal surface than many other lasers used for vision
correction.
Eye
Tracking Technology
Due to the remarkable speed of both the eye and the ALLEGRETTO WAVE
procedure, the laser beam needs to be constantly and minutely adjusted
to the position of the eye at any given time. Every 4-6 milliseconds,
the eye's location is measured and the internal mirrors of the ALLEGRETTO
WAVE are automatically aligned. Right before the pulse is released,
a second check is made to confirm that the eye has not moved. This
happens 200 times every second, once for every laser pulse. If,
at any time, the eye moves too quickly to be measured or moves out
of range, the laser will stop and wait for the eye to move back
into position.
Speed
Currently, the ALLEGRETTO WAVE is the fastest vision correction
laser for LASIK available in the United States. At 200 laser bursts
per second, it only takes about four seconds of treatment to correct
one diopter. Of course, spending less time under the laser means
less stress and discomfort for the patient.
