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.

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.

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.

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.
