WaveLight® Allegretto Wave® Eye-Q Laser

Excimer Laser System
Only LASIK with WaveLight® offers the flexible performance of Wavefront Optimized® LASIK, for faster treatment of more patients with less effort. Wavefront Optimized® LASIK depends on the speed and safety of the advanced WaveLight® Allegretto Wave® Eye-Q Laser, precision-engineered for faster, accurate procedures.

Equipped with all the advantages of the proven WaveLight® Allegretto Wave® Eye-Q Laser technology, the WaveLight® Allegretto Wave® Eye-Q Laser optimizes laser vision correction.

The WaveLight® Allegretto Wave® Eye-Q Laser was designed based on an idea that was once only imagined: a system with shortened surgery times, innovative and reliable eye-tracking, and a clear ergonomic concept.

Together, these innovations allow the WaveLight® Allegretto Wave® Eye-Q Laser to provide excellent clinical results in both Wavefront Optimized® and Wavefront-Guided laser vision correction.

The high-speed laser and eye tracker of WaveLight® Allegretto Wave® Eye-Q Lasers offer a unique combination of efficiency and safety, for faster throughput, reduced environmental exposure, and excellent outcomes. In addition, its proven, state-of-the art technology provides the physician and patient both safety and reliability, with a low rate of complications and retreatments.3

For Hyperopia and Hyperopic Astigmatism

The combination of PerfectPulse Technology and fast speed make the Allegretto Wave Eye-Q 400 Excimer Laser System (Alcon, Fort Worth, Texas) an ideal platform for treating hyperopia, especially in patients who are also astigmatic.Because the laser operates at 400 Hz, it can treat a diopter of hyperopia in two seconds.Procedure time is extremely fast, which leaves less time for external influences to come into play during treatment.The effects of factors such as humidity and dehydration are reduced.

The precision of the Allegretto Wave Eye-Q 400 Hz laser’s PerfectPulse Technology helps to improve patients’ post-op quality of vision. The energy stability of the laser pulses is continuously monitored and adjusted from the time of generation to ensure they are applied to the cornea in a uniform fashion. At the same time, a high speed eye tracker follows the eye’s fastest movements.The laser does not fire the pulse unless the eye is in the proper position. The laser delivers additional pulses in the periphery so that the cornea maintains its natural prolate shape.

"Where all of this helps is in creating a more gradual transition zone," Dr. Markan said.Most present as latent hyperopes, meaning they had been able to see relatively well until they were no longer able to accommodate. It’s not until presbyopia begins to set in that they are no longer happy with their vision. First we have to establish where they want to be able to see after surgery, at near or distance. Realistically, they may be looking for a distance vision alternative, especially males. Females are more likely to be using a monovision solution prior to surgery, which makes monovision a great option for surgery, too. However, if patients say they want good vision at all distances, we need to consider whether refractive lensectomy might be a better strategy for them than LASIK.”

Dr. Markan may also recommend refractive lensectomy for hyperopes in cases where LASIK would require steepening the cornea to a point where other problems, such as dry eye, could arise.I don’t like to make a cornea too steep. I avoid going beyond 49–49.5 K. The Wavelight laser is approved to treat up to 6 D spherical equivalent in hyperopes, which is a nice range, and many surgeons treat to that maximum with great success. However, I tend to not perform LASIK for corrections higher than +3 D.” In addition, he assesses how much influence the patient’s lens is having on overall refractive error. “We’ve learned over time that we don’t want to treat a lens problem on the cornea. Some patients may also have early nuclear sclerotic changes, so we don’t want to perform a procedure that is of short lived benefit. In cases where LASIK is a better fit than refractive lens exchange, the Allegretto Wave Eye-Q 400 Hz laser gives surgeons the distinct advantage of being able to choose between a wavefront-guided or Wavefront Optimized approach. Dr. Markan recommends a wave front-guided procedure for patients whose RMSh value is 0.4 or higher.

That’s the beauty of this platform. You can choose between the two options based on the individual patient,” he said. “My recommendations for hyperopes revolve around presbyopia and what each patient needs or wants. Once the pre-op assessment and discussions with the patient lead us to choose LASIK, the Allegretto Wave Eye-Q system is my platform of choice for hyperopia and hyperopic astigmatism.”
