Allegretto 

The Allegretto Wave Eye-Q is the safest and most advanced technology in use for LASIK surgery today, providing outstanding vision for people who are nearsighted, farsighted, astigmatic, or presbyopic.

Emory Vision purchased the first Allegretto Wave Eye-Q laser in Georgia.  Nationally recognized studies by Emory Vision physicians have verified the superior results achieved through this new technology.

The Allegretto Wave Eye-Q treats a larger area of the eye than other lasers, and the Emory Vision studies found this to be especially beneficial in reducing higher-order aberrations that affect night vision.  This finding is acknowledged in the FDA ruling approving the Allegretto Laser, which states:  “Patient reports of glare from bright lights, light sensitivity, night driving glare and visual fluctuations all improved after LASIK.” (FDA – P020050, 10/07/03)

The FDA ruling also reports that in clinical studies, 87 per cent of patients having Allegretto Wave surgery had 20/20 vision or better one year after the procedure, and 99 per cent had 20/40 or better, the standard for driving without glasses in most states

Wavefront Technology 

One of the most exciting improvements used in vision correction surgery is the use of Wavefront technology, which provides an advanced way to measure optical distortions in the eye.  Measuring and treating these distortions goes well beyond just determining if the patient is nearsighted, farsighted, and/or has astigmatism. 

As a result, physicians can now customize the LASIK procedure according to each individual patient’s unique vision correction needs.  The system works by measuring how light is distorted as it passes into each eye and is reflected back.  Emory Vision uses two Wavefront devices and compares the results to ensure the best possible vision correction.

According to the Eye Surgery Education Council, a leading group for which Emory Vision’s Medical Director, Doyle Stulting, MD PhD, has served in leadership roles, states that wavefront technology functions as a roadmap for LASIK surgery, providing benefits to the patient during both the evaluation and treatment process.

The Council has established the following:

• During the patient evaluation process, wavefront provides the physician comprehensive individual diagnostic information, not available using earlier technologies. Thus, before surgery even begins, the surgeon is better able to determine the appropriate course of treatment.
• During treatment, wavefront allows the surgeon to tailor the laser beam settings, making the surgical procedure itself more precise. In this way, wavefront technology offers the patients sharper, crisper, better quality vision, as well as a reduction in nighttime vision difficulties, such as halos and glare.
• Wavefront technology is an adjunct tool used to enhance an already safe and effective procedure. As the most common form of vision correction surgery, LASIK has already benefited millions of patients. The increased safety and the improved quality of vision benefits of customized procedures are an important technological advancement for patients and physicians alike.

Allegretto Wave Eye-Q Technology

The Allegretto Wave Eye-Q is the first new laser to receive approval in the United States since 1999. Emory Vision purchased the first Allegretto Wave Eye-Q laser in Georgia and has been treating patients with it since July 2004.

It is the fastest laser system in the United States today, using PerfectPulse Technology to safely and accurately control every single laser pulse from start to finish. The system was designed to perfection based on knowledge and experience. It represents a new generation of refractive technology conducting High Performance Vision Correction that patients can rely on night and day. The Allegretto Wave Eye-Q offers a customized treatment that incorporates wavefront principles to patients with nearsightedness and even farsightedness.

Every procedure is tailored to the patients’ corneal curvature and refraction with the intention to preserve the natural aspheric cornea shape and to maintain or improve quality of vision and visual acuity.

Emory Vision uses the Allegretto Wave Eye-Q laser because is has shown in clinical studies to provide superior results. The Allegretto Wave Eye-Q can preserve or improve quality of vision in regards to glare and night driving glare. The majority of myopia patients treated with the Allegretto Wave Eye-Q achieved 20/16 or better one year after LASIK.

Approved by the US Food and Drug Administration (FDA) in 2003, Allegretto Wave Eye-Q technology can be coupled with a cornea analysis using state-of-the-art wavefront technology to treat all of the conditions LASIK surgery has traditionally corrected, as well as a range of vision problems that could not be addressed before. These problems, called higher order aberrations, include problems with vision during low-light, including glare and halos. This technology improves visual acuity and visual quality.
