Featuring all advantages of the renown 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 ophthalmic WaveLight 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 that gives the option of choosing the optimal treatment for the patient from all currently known methods of refractive surgery. |
| Q-Value Adjustment |
| |
| The adjustment of the corneal asphericity (also referred to as the ?¡ãQ-Value?¡À) may have influence in affecting the visual acuity under mesopic and scotopic conditions. The Q-Value is different with every patient, but probably not optimal for the patient's visual acuity, as external factors such as wavefront aberrations of the crystalline lens have a considerable effect on it. |
| In addition to wavefront-optimized, A-CAT (wavefront-guided) and T-CAT (topography-guided) treatments, Q-Value Adjustment now adds a 4th dimension to the treatment of vision disorders by customizing the asphericity of the Cornea. This allows customization and offers a treatment ideally adjusted to the individual needs of the patient. |
| Advanced Fine Tuning Capabilities |
| |
| With the implemented advanced fine tuning options, the physician has the possibility to plan an extended treatment. |
| The Surgeon can adjust the optical zoneas well as the transitional zone by 0.1mm steps. The refraction input can be leveled in 0.01D. This allows the user to ideally plan the treatment according 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 physicians to accurately align the patient's eye for all types of treatments, which allows a more precise correction of astigmatism and higher order aberrations. |
| Speed |
| Efficient treatment with fast pulse repetition minimizes the dehydration effect of the Cornea as well as external influences during operation. |
| In order to further optimize the refractive treatment itself, the repetition rate in the ALLEGRETTO WAVE Eye-Q was enhanced to 400 Hz. This makes the ALLEGRETTO WAVE Eye-Q the fastest excimer laser currently available on the market. It allows physicians to perform a 6-diopter myopia correction on a fully- corrected optical zone of 6.5 mm within 15 seconds. |
| Wavefront-Optimized Ablation Profiles |
| |
| The ALLEGRETTO WAVE excimer lasers were the first lasers that use wavefront-optimized ablation profiles, thus integrating an important wavefront-guided treatment feature in standard laser vision correction. Laser surgery without a wavefront-optimized ablation profile may cause alterations of the corneal asphericity in the peripheral correction area. These so-called induced spherical aberrations in the wavefront image may cause an alteration of the patient's night or mesopic vision. |
| A wavefront-optimized ablation profile is designed to prevent such spherical aberrations of the patient's Cornea, whereas the risk of surgery-related vision problems is minimized. |
| Small Beam Diameter |
| |
| Due to the small laser spot with a diameter of 0.95mm (0.68mm FWHM, Full Width Half Maximum), ALLEGRETTO WAVE laser systems operate with a very high resolution for even finest corrections of the Cornea - as it is required for customized laser vision correction. |
| True Optical Zones |
| The small diameter of the spot allows a high-precision contouring of the correction profile, while minimizing the total overall ablation depth. A wavefront-optimized beam profile together with small laser spots allow operations in a large optical zones and ensuring optimal transitional zones. |
| The ALLEGRETTO WAVE Eye-Q is the ultimate laser for refractive surgery. It has a ceramic laser head with a repetition rate of 400Hz 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 user-friendly 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. |
