The difference is our Technology

THE DIFFERENCE IS OUR TECHNOLOGY
In keeping with our ongoing commitment to remain at the forefront of vision correction, the Laser Eye Center now offers the newest and most technologically advanced laser system, the ALLEGRETTO WAVE excimer laser. We are proud to treat our patients with the  ALLEGRETTO WAVE laser system.
 This advancement in vision correction technology offers patients increased speed, accuracy and safety. In fact, the ALLEGRETTO WAVE Eye-Q is one of the fastest excimer laser systems  today.
The ALLEGRETTO WAVE Eye-Q Excimer Laser is the newest generation of excimer laser technology and is the first system to receive concurrent approval for the treatment of both nearsightedness and farsightedness. The treatment profile for this laser was developed after intense study of individuals who have what is called “super vision,” or vision that is better than 20/20. The laser reshapes the cornea of your eye to mimic the pattern of eyes with “super vision” with unparalled customization. Due to the laser’s unique wavefront-optimized ablation algorithm, the system delivers superior clinical results and a maximum level of safety for our patients.
The ALLEGRETTO WAVE Eye-Q Excimer Laser is a “WaveFront-optimized” system. WaveFront technology not only corrects a patient’s prescription, but aims to improve the “quality” of vision during daylight and prevent problems with night vision. The system also has a unique eye-tracking system which automatically adjusts to changes in pupil size during treatment.
 
PERFECTPULSE TECHNOLOGY™
PerfectPulse Technology represents a new approach to laser vision correction — it accounts for speed, precision, and safety in 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. As a result, every laser pulse is completely controlled and accurate, achieving the most accurate level of correction possible.
Q-VALUE ADJUSTMENT
Adjustment of the corneal asphericity (also known as the “Q-Value”) can have influence in affecting the visual acuity in mesopic and scotopic conditions. Q-Value Adjustment allows the physician to customize the asphericity of the patient′s cornea. Additional feature of this software is the ability to fine tune optical zones, transition zones and correction values.
In addition to wavefront optimized, A-CAT (wavefront guided) and T-CAT (topography guided) treatments, Q-Value Adjustment now offers a 4th dimension to the treatment of vision disorders. This provides true customization and offers a treatment ideally adjusted to the individual needs of the patient.
CROSS LINES
A cross line projector is integrated into the ALLEGRETTO WAVE Eye-Q. This device will help the physician to accurately align the patient′s eye for all types of treatments, therefore enabling more precise correction of astigmatism and higher order aberrations
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 Eye-Q’s laser is a precise, controlled beam of energy, which translates to heat. To make sure that this beam never causes any sort of adverse heating effect on the cornea, ALLEGRETTO WAVE’s PerfectPulse Technology places the laser pulses in such a way that only every fifth pulse overlaps. Not only does this preclude unwanted heating effects, it is one of the ways that ALLEGRETTO WAVE Eye-Q achieves a rounder, more natural corneal surface than many other lasers used for vision correction.
SMALL BEAM DIAMETER
Due to the small laser spot with a diameter of 0.95mm (0.68mm FWHM, Full Width Half Maximum), the ALLEGRETTO WAVE laser systems work with a very high resolution and are able to create finest curvatures on the cornea - as required for customized laser eye surgery.
 
EYE TRACKING TECHNOLOGY
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 4-6 milliseconds, the eye’s location is measured and the internal mirrors of the ALLEGRETTO WAVE Eye-Q are automatically aligned. Right 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 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.
 
 
SPEED
The ALLEGRETTO WAVE Eye-Q is probably the fastest vision correction laser . At 400 treatment pulses per second, it only takes approximately two seconds of treatment to correct one diopter. Of course, spending less time under the laser means less stress and discomfort for the patient.This makes the ALLEGRETTO WAVE Eye-Q the fastest excimer laser currently available on the market.
WAVEFRONT TECHNOLOGY
One of the most innovative features of the ALLEGRETTO WAVE Eye-Q is its use of 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.
ALLEGRETTO WAVE Eye-Q changes all that. Understanding that the cornea is a sphere, ALLEGRETTO WAVE uses a proprietary treatment that is adjusted to the patient’s individual corneal curvature. The ALLEGRETTO WAVE Eye-Q sends extra pulses to the peripheral cornea area in order to compensate for the angle of the laser. In this manner, the spherical shape of the cornea is preserved to a degree that older lasers simply could not achieve. This compensation, combined with the incredibly small, 1mm size of the laser, produces a smooth, effective optical zone that results in what can only be described as high performance vision.
Imagine a glass ball. If you took a flashlight and aimed it directly at the top of the ball, the light would form a circular shape on the surface of the ball. If you now aimed the flashlight towards the side of the ball, the light would form an elliptical shape and not seem as bright anymore. This is because the same amount of light is suddenly distributed over a larger area and some of the light is reflected away due to the angled surface of the glass ball.
 
These so-called induced spherical aberrations in the wavefront image may result in the patient experiencing problems with night vision or under mesopic conditions.
Utilizing a wavefront optimized ablation profile is designed to prevent such spherical aberrations of the patient′s cornea, thereby minimizing the risk of refractive surgery-related vision problems.
 
HIGH PERFORMANCE VISION
Large Optical Zones

ALLEGRETTO WAVE Eye-Q 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.
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. ALLEGRETTO WAVE Eye-Q is able to produce the largest available optical zone, virtually eliminating glare and night vision problems associated with older generation lasers.
Featuring all advantages of the well-known ALLEGRETTO WAVE, the ALLEGRETTO WAVE Eye-Q is a further step towards optimizing the process of laser vision correction. With customized ablation in mind, all ophthalmic WaveLight products have been designed as a fully-integrated concept in order to provide physician and patient the highest level of safety and reliability in refractive surgery.
The ALLEGRETTO WAVE Eye-Q is the first device ever to provide the physician with the possibility of choosing the optimal treatment for the patient from all currently known possibilities of refractive surgery.
