ALLEGRETTO WAVE Excimer LASER: : FDA Best Clinical Results
Allegretto Wave Excimer Laser is the first laser developed specifically for customized treatment by aberrometry by German engineers from WaveLight Inc. This laser has obtained the best results from Food and Drug Administration (FDA) clinical trials.
Specifications include the highest frequency and speed of ablation, with high accuracy, allowing the surgeon to perform high quality treatment with conventional or aberrometry techniques.
Re-treatment with Allegretto Wave Excimer Laser is very low. (3% in average) according to the personal experience of Dr Assaf.
Allegretto Wave Excimer Laser uses software to treat myopia, hyperopia, astigmatism and higher order optic aberrations.

Particular specification :
1. Gaussian Ablation Profile
Gaussian Ablation profile allows a slight overlapping of peripherical laser pulses in order to obtain a smooth ablation without ridges or stepping and therefore a better quality of vision.
- Small beam diameter (0,95 mm)
- Gaussian ablation Profile
- Ablation Area without waving or steps
- Smooth and regular ablation
- Ablation profile advantageous for customized treatment by aberrometry

2. Small Scanning Spot
High- speed scanning mechanism incorporated in Allegretto Wave Excimer Laser allows to perform 200 laser pulses per seconds to achieve a better distribution of the energy on the corneal surface.
- High energy system
- Treatment of few seconds per diopter homogeneous
- Smooth and regular ablation
- Customized treatment optimized by aberrometry
- Large optical zones

3. Active Infrared Eye Tracking System
Allegretto Wave Excimer Laser uses an infrared eye tracking allowing fast treatment with laser pulses centred on the visual axis, even during saccadic movements of the eye during treatment.
Three infrared sources give independent tracking positions of the iris 250 times per second insuring a precise positioning of each pulse on the ablation area.
- Scanning mirrors movement is from 4 to 8ms
- Tracking without dilation
- Automatic centring before treatment
- No cases reported of failure of the infrared tracking mechanism

4. Optical Zones
Allegretto Wave Excimer Laser produces real large optical zones that can be measured by corneal topography. Allegretto Wave Excimer Laser performs optical zones from 6 to 8mm with real small transition zones. Its software allows a LARGE SUPERFICIAL CIRCULAR ABLATION PROFILE with corneal tissue saving.
- Prolate post-operative corneal shape (natural shape)
- Large optical zones from 6 to 8mm
- Small transition zones
- Large optical zone measured by corneal topography
- Ablation profile to save corneal tissue

5. Flexible Mechanism
Allegretto Wave Excimer Laser uses a driven flexible system. It is independent from mask lens or diaphragm. The Software allows different treatment parameters and optimized treatment by aberrometry.

6. Plume evacuator
The plume evacuator allows clean and clear treatment. The permanent evacuator system reduces odors and risks of infection. It is designed specifically to have a draft-free airflow and evacuate residues that can fall on cornea during the treatment to obtain a precise treatment.
