Equipped with all the advantages of the well proven Alcon ALLEGRETTO WAVE Excimer Laser technology, the ALLEGRETTO WAVE Eye-Q 400 Hz Excimer Laser is one step closer to optimal laser vision correction.

The Alcon ALLEGRETTO WAVE Excimer Laser was designed based on an ideal that was once only an imagination. The idea was to create a system with shortened surgery times, innovative and reliable eye tracking and a clear ergonomic concept. The Alcon ALLEGRETTO features enhanced pulse frequency of 400 Hz providing even faster treatments. The Alcon ALLEGRETTO WAVE also includes an eye-tracking system adjusted to the high speed of the laser beam and a cross line projector for precise centration.

The Alcon ALLEGRETTO WAVE features proven state-of-the-art technology providing excellent results in both Wavefront optimized and Wavefront guided laser vision correction. The Alcon ALLEGRETTO WAVE Eye-Q 400 Hz Excimer Laser provides the physician and patient both safety and reliability.

Alcon ALLEGRETTO WAVE – Light Weight and Space Saving
Fitting through standard doorways, the Alcon ALLEGRETTO WAVE Eye-Q Excimer Laser can be accommodated even in the smallest operating rooms. Compared to other systems, the ALLEGRETTO is light-weight and also suitable for historic buildings.

Expensive architectural changes to the operating room are, in most cases, not needed, because of the lasers´ sealed beam path, which is just one of the reasons for the ALLEGRETTO’s tolerance towards humidity and temperature fluctuations.

Alcon ALLEGRETTO WAVE – Cross Line Projector

Precise Centration
Finding the eye’s correct treatment position is one of the most important factors in obtaining an excellent refractive outcome especially in high astigmatic corrections.
The Alcon ALLEGRETTO WAVE Eye-Q Excimer Laser’s integrated cross line projector provides the surgeon with an exact alignment of the head’s and eye’s position. The target diode which generates a red light cross on the patient’s face shows the right position in horizontal and vertical direction coordination with the manual marks.

Alcon ALLEGRETTO WAVE – Additional Equipment

Comfort, Practicality and Ease-of-Use

• The Alcon ALLEGRETTO WAVE Excimer Laser system offer many features that support comfort, practicality and ease-of-use.
• The ALLEGRETTO WAVE offer an integrated plume evacuator which removes fumes and odors which protect the respiratory tracts of patients and surgeons.
• Considering every aspect of the refractive procedure, the Alcon ALLEGRETTO WAVE Excimer Laser systems contain a built-in slit lamp.
• There is no need to move the patient into a different room in order to check the flap position, the interface, or to perform a flap re-lift.
• A 100 W, ultra-bright xenon light source provides excellent illumination.
• The Alcon ALLEGRETTO WAVE offers an optional uninterrupted power supply (UPS) which delivers reliable performance, even under unreliable environmental electrical conditions or loss of power.
• In order to maintain highest possible hygienic standards, all parts of the Alcon ALLEGRETTO WAVE Excimer Laser system that might be touched during surgery are fitted with sterile caps.

Alcon ALLEGRETTO WAVE PerfectPulse Technology

Safety and Precision

• Alcon ALLEGRETTO WAVE Excimer Laser systems apply PerfectPulse Technology to ensure safe and precise work at high speed.
• Alcon ALLEGRETTO WAVE PerfectPulse Technology simply means that every laser pulse is completely controlled from its generation to the point when it contacts the cornea.
• Each ultra-thin laser pulse is used to sculpt the corneal surface with the utmost precision.
• In order to further enhance the safety and precision of the treatment, the Alcon ALLEGRETTO WAVE PerfectPulse Technology uses advanced high-speed eye-tracking to follow the eye’s fastest movements and to ensure an accurate placement of each laser pulse on the cornea.
• During the treatment, the energy stability of every pulse in the Alcon ALLEGRETTO WAVE is controlled on the basis of a smart energy control program which automatically balances the energy levels to ensure that each laser pulse creates the same accurate result.

Alcon ALLEGRETTO WAVE Aspheric Ablation – True Optical Zones

• In order to maintain the patient’s refraction and corneal curvature, it is important to understand the behavior of every laser pulse when it meets the eye. When laser light contacts the center of the cornea, it is fully absorbed. However, in the periphery, the angle of incidence resulting from the cornea’s curved shape may cause energy reflections.
• The Alcon ALLEGRETTO WAVE Excimer Laser systems apply additional pulses in these peripheral areas to compensate for the energy loss, and to achieve the desired post-operative aspheric contour even in the outer areas of the cornea. In order to precompensate for the possible induction of spherical aberrations, the Alcon ALLEGRETTO applies even more pulses depending on the patient’s individual corneal steepness.
• The effect of higher-order aberrations increases with pupil size. Hence the effective optical zone size should correspond with the pupil. Large transition zones induce higher-order aberrations, thereby fostering vision problems such as halos and glare.
• Controlling the peripheral ablation allows the Alcon ALLEGRETTO WAVE Excimer Laser system to create large, true optical zones with a minimized transition zone.
• By treating larger optical zones with a diameter of up to 8 mm, post-operative glare and halos may be minimized.
