Speed. Precision. Better Vision
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 Wave Light 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.

Q-Value Adjustment
Adjustment of the corneal asphericity (also referred to as the “Q-Value”) can have influence in affecting the visual acuity in mesophic and scotopic conditions. The Q-Value is different with every patient, but probably not optimal for the individual’s visual acuity, as other factors such as wave front aberrations of the crystalline lens have a considerable effect.

In addition to wave front –optimized, A-CAT (wave front-guided) and T-CAT (topography –guided) treatments, Q-Value Adjustment now offers a 4th dimension to the treatment of vision disorders by customizing the asphericity of the cornea.

This provides true customization and offers a treatment ideally adjusted to the individual needs of the patient.

Advanced Fine Tuning Capabilities
Wit the implemented advances fine tuning capabilities, the physician has the possibility of an extended treatment planning. The surgeon can adjust the optical zone in 0.1 mm steps as well as the transition zone. The refraction in put can be changed in 0.01D increments. This allows the user toppling the treatment ideally 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 with defined axis.

Speed
Efficient treatment with fast pulse repletion minimizes the effects of dehydration of the cornea as well as external influences during surgery. In order to further the refractive procedure itself, the repletion rate has been increased to 400 Hz in the ALLEGRETTO WAVE Eye-Q. This allows the physician to perform a 6-diopter myopia correction on a fully corrected optical zone of 6.5 mm within 15 seconds.

Wave front –Optimized Ablation Profiles
The ALLEGRETTO WAVE excimer lasers were the first lasers to use wave front-optimized ablation profiles, thus integrating an important wave front guided treatment feature in standard laser vision correction.

Laser surgery executed without a wave front –optimized ablation profile may result in altering the corneal asphericity in the peripheral correction area. These so- called induced spherical aberrations in the wave front image may result in the patient experiencing problems with night vision or under mesopic conditions.
Utilizing a wave front-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.

Small Beam Diameter
Due to the small laser spot with a diameter of 0.95 mm (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 vision correction.

True Optical Zones
The small spot creates the desired contour of the correction profile with utmost precision, thereby minimizing the total overall ablation depth. Combining wave front optimized beam profile with small laser spots allows for the creation of a large effective optical zone with a very small transition area.

The ALLEGRETTO WAVE Eye –Q is the ultimate laser for refractive surgery. It includes a ceramic laser head with a repetition rate 400 HZ and a solid –state power supply for long lifetime and energy stability.

It also features a fast video-based closed loop eye tracker and a nitrogen purged beam path.
The easy-to-energy calibration and closed loop energy control integrated in the ALLEGRETTO WAVE Eye-Q significantly increases the working comfort for the physician and the safety for the patient.
