Excimer Laser

Allegretto Wave Excimer Laser.

Using the Allegretto Wave Excimer Laser, Wavelight provides the newest technology in a small footprint design. Fewer optical surfaces and reduced gas consumption mean lower cost per procedure, which was the primary design goal for this office based refractive laser.

"Flexible System" The Allegretto Wave Excimer Laser is a software driven flexible system. The laser does not rely on masks, lenses and diaphragms to size and scan the treatment beam. The software driven system allows for data input from a variety of sources, including manifest refraction data, as well as topography and Wavefront data to optimise the treatment.

Active Eye Tracking System The Allegretto Wave's active eye tracking technology allows precise real-time tracking of the laser beam, ensuring accurate placement of each pulse, even in the presence of saccadic eye movements. The three infrared illumination sources allow independent position tracking of the eye 250 times per second, ensuring accurate placement of each pulse and correct centring of the treatment on the patients cornea.

Small Scanning Spot The high-speed scanning mechanism incorporated into the Allegretto Wave Excimer Laser allows the laser to deliver 200 laser pulses per second and to achieve even distribution of the laser energy over the treatment zone on the cornea. Gaussian Beam Profile The placement of partially overlapping Gaussian pulses by the Allegretto Wave Excimer Laser results in a smooth surface without ridges and grooves, which detract from visual acuity after surgery.

Wavelength optimised and true optical zones The wavefront optimised nomogram allows for large true optical zones and excellent mesopic vision after treatment.
