Technology - ALLEGRETO WAVE 400
At Excel Laser Vision we are committed to providing the latest, most effective and unobtrusive eye care services available. From our friendly, knowledgeable office staff to our licensed eye care professionals we undergo continual training and certification to ensure that we deliver the highest levels of patient care available in the Greater Los Angeles area.
In order to offer the best service around, we also use the latest, and best technology in existence today, the ALLEGRETTO WAVE 400.
Wavefront Optimized™ Laser Vision Correction
One of the most innovative features of the ALLEGRETTO WAVE® is the way it uses wavefront-optimized technology to automatically compensate for the curvature of the cornea. In earlier laser correction systems, the “optical zone,” or area of correction, was centered on the front of the cornea; the result was a flattened circular area that ended with an abrupt edge, causing unwanted side effects like poor night vision, glare, and halos.
See Like Never Before
ALLEGRETTO WAVE® is capable of producing some of the largest available optical zones. The optical zone refers to the portion of the cornea that has been corrected by the laser. A larger than normal optical zone is especially important for night vision, and for patients with very large pupils. If a patient’s pupil is larger than the optical zone, they may experience poor peripheral vision, poor night vision, and a higher than normal incidence of “halos” and glare. In the past, this has been one of the biggest drawbacks to conventional laser correction surgery.
Vision—Accuracy, Total Control
ALLEGRETTO WAVE®’s revolutionary approach to laser vision correction minimizes problems associated with older generation lasers, such as night vision reduction, glare, and halos.
Safety—PerfectPulse Technology™
Smart energy control and eye tracking technology combine to provide an ultra-fast solution to laser vision correction. Innovative and redundant safeguards make ALLEGRETTO WAVE® a leader in the field.
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 released. 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.
