Smart, Fast Laser Surgery Technology
PerfectPulse Technology™ for laser vision correction accounts for much of the speed, precision, and safety of the WaveLight® EX500 excimer laser and offers improvements 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 500 times per second. As a result, every laser pulse is completely controlled, allowing for 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.
The WaveLight® EX500 excimer 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 WaveLight® EX500 excimer laser is able to achieve 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 WaveLight® Ex500 procedure, the laser beam needs to be constantly and minutely adjusted to the position of the eye at any given time. Every two milliseconds, the eye’s location is measured and the internal mirrors of the WaveLight® EX500 are automatically aligned. Just before the pulse is released, a second check is made to confirm that the eye has not moved. This happens 500 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.
The WaveLight® Refractive Suite is the fastest refractive surgery platform available in the United States, and we are very proud to have it here in Pittsburgh. At 500 laser bursts per second, it takes only about 1.4 seconds of treatment to correct one diopter. Of course, spending less time under the laser means less stress and discomfort for the patient.
Laser Correction Surgery
The WaveLight® EX500 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 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. Wavefront Optimized™ technology built into the WaveLight® EX500 addresses this limitation.
Better Night Vision and Glare Control
At night and in dark conditions, the pupil becomes larger to permit the maximum amount of light to enter the eye. Laser eye correction needs to take this fact into account. If the optical zone is smaller than the size of the pupil at its largest, there is a good chance that the patient will experience poor night vision or problems with glare and halos around bright objects such as oncoming headlights. WaveLight® EX500 zone, virtually eliminates glare and night vision problems associated with older generation lasers.
When it was approved in 2003 as the first new laser in five years, the FDA granted the ALLEGRETTO WAVE® the widest approval range ever initially given to a new laser for both myopic and hyperopic vision correction. Since then, the results have been astoundingly positive.
On gaining FDA approval in 2006, the ALLEGRETTO WAVE® Eye-Q took this tradition of excellence another step forward, providing proven superior clinical results, as shown by the following statistics:
- At one year after treatment, more than 93% of patients said they saw at least as well or better than they had with glasses or contacts before treatment.
- More than 98% of patients achieved 20/40 vision one year after treatment; 20/40 is the level of visual acuity required to pass most driving tests.
- Nearly 60% of near-sighted patients achieved 20/16 vision after one year of treatment.
- Both near- and far-sighted patients reported an improvement in their reaction to bright lights and night driving glare after ALLEGRETTO WAVE® Eye-Q treatments. In addition, near-sighted patients reported an improvement in sensitivity to light.
- Predictable results are the norm for the ALLEGRETTO WAVE® Eye-Q. More than 90% of patients achieve refraction within 1 diopter of their target correction.

Bladeless, All-LASER LASIK
AIO is proud and excited to announce the newest addition to our refractive arsenal for LASIK, the WaveLight FS200 Femtosecond LASER. AIO can now offer to all of our patients, bladeless, ALL-LASER LASIK.
The Femtosecond laser used in all-laser LASIK directs tiny rapid pulses of infrared light to a precise depth within the cornea to create the flap. The depth is determined by the surgeon and is entered into the computer that controls the laser.
These high-energy light pulses separate corneal tissue at the molecular level by a process called photo-disruption, creating microscopic bubbles of carbon dioxide and water at their point of impact.
The laser moves back and forth across the eye creating a uniform layer of these bubbles at the junction between what becomes the back surface of the corneal flap and the underlying corneal tissue. The femtosecond laser creates 15,000 laser pulses per second. It features a faster flap creation time. The 200 KHz FS200 laser delivers precise, predictable outcomes. It also offers tailored performance. The laser offers adjustable hinge position and size, variable side-creation angles, flap sizes and shapes. This allows our surgeons to expand their treatment options. It combines a small focus with low pulse energy and a unique creating pattern for accurate flap edges and smooth stromal beds. Utilizing the proprietary beam control check, the WaveLight FS200 accommodates a wide range of patient variables for more consistent flaps.
