WAVELIGHT ALLEGRETTO WAVE Eye-Q

Since July 2004, Dr Vryghem is privileged to be the first eye surgeon in Belgium who performs laser treatments with the new WAVELIGHT ALLEGRETTO WAVE Eye-Q excimer laser at his practice in Brussels. Featuring all advantages of the well-known ALLEGRETTO WAVE, the new ALLEGRETTO WAVE Eye-Q is a further step towards optimizing the process of laser vision correction. It aims to provide physician and patient the highest level of safety and reliability in refractive surgery.

Speed - Precision - Better Vision

The new 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 known as the "Q-Value") can have influence in affecting the patient's sight in mesopic (half dark) and scotopic (dark) 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.

Speed
Efficient treatment with fast pulse repetition minimizes the effects of dehydration of the cornea as well as external influences during surgery. In order to further optimize the refractive procedure itself, the repetition rate has been increased from 200 Hz in the ALLEGRETTO WAVE to 400 Hz in the ALLEGRETTO WAVE Eye-Q. This makes the ALLEGRETTO WAVE Eye-Q the fastest excimer laser currently available on the market! It allows the physician to perform a 6-diopter myopia correction on a fully corrected optical zone of 6.5 mm within 15 seconds, whereas the same treatment took 30 seconds with the ALLEGRETTO WAVE. The frequency of the eye-tracker has been increased to 400 Hz to match with the speed of the laser, which means that the gaze of the patient is followed with an even higher accuracy. Besides the medical advantages, the higher repetition rate is also improving the comfort of the patient during the laser treatment.
Cross Lines

A cross line projector has been 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.


Wavefront Optimized Ablation Profiles

The ALLEGRETTO WAVE excimer lasers were the first lasers to use wavefront optimized ablation profiles, thus integrating an important wavefront guided treatment feature in standard laser vision correction. Laser surgery executed without a wavefront optimized ablation profile may result in altering the corneal asphericity in the peripheral correction area. These so-called induced spherical aberrations in the wavefront image may result in the patient experiencing problems with night vision or under mesopic (twilight) 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.

Small Laser Beam

Due to the small laser spot with a diameter of 0.95 mm, 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 a wavefront optimized beam profile with small laser spots allows for the creation of a large effective optical zone with a very small transition area.
