PerfectPulse Technology™ represents a new approach to laser vision correction. It accounts for much of the speed, precision, and safety of the ALLEGRETTO WAVE® Eye-Q 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 400 times per second. As a result, every laser pulse is completely controlled, allowing for 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.
The ALLEGRETTO WAVE® Eye-Q 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® Eye-Q is able to achieve 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® Eye-Q procedure, the laser beam needs to be constantly and minutely adjusted to the position of the eye at any given time. Every four to six milliseconds, the eye’s location is measured and the internal mirrors of the ALLEGRETTO WAVE® Eye-Q are automatically aligned. Just before the pulse is released, a second check is made to confirm that the eye has not moved. This happens 400 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® Eye-Q is the fastest vision correction laser for LASIK available in the United States. At 400 laser bursts per second, it takes only about two seconds of treatment to correct one diopter. Of course, spending less time under the laser means less stress and discomfort for the patient.
