Allegretto Wave Eye-Q
Featuring all the advantages of the well-known Allegreto Wave, the Allegreto Wave Eye-Q is a further step towards optimizing the process of laser vision correction. All ophthalmic WaveLight products have been designed as to provide physician and patient the highest level of safety and reliability in refractive surgery. The Allegreto 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 influence visual acuity in mesopic and scotopic conditions. Q-Value Adjustment allows the physician to customize the asphericity of the patient′s cornea. Additional feature of this software are 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.
Cross Lines
A cross line projector is integrated into the Allegreto Wave Eye-Q. This device will help the physician to accurately align the patient′s eye for all types of treatments, enabling more precise correction of astigmatism and higher order aberrations.
Speed
Efficient treatment with fast pulse repetition minimizes 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 to 400 Hz in the Allegreto Wave Eye-Q. This makes the Allegreto 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 less than 15 seconds.
Wavefront Optimized Ablation Profiles
The Allegreto 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 eye 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 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 Beam Diameter
Due to the small laser spot with a diameter of 0.95mm (0.68mm FWHM, Full Width Half Maximum), the Allegreto Wave laser systems work with a very high resolution and are able to create finest curvatures on the cornea – as required for customized laser eye surgery.
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.
