Significant Advantages Of Allegretto Wave® Over Other Laser Eye Surgery Options

By: Dr. Andrew Caster

Large Optical Zones

The ALLEGRETTO WAVE® is capable of producing some of the largest available optical zones. The optical zone refers to the portion of the cornea that has been corrected by the laser. A larger optical zone is especially important for night vision and for patients with very large pupils. According to a top Lasik doctor Los Angeles patients may have pupils that are larger than the optical zone, and may experience poor peripheral vision, poor night vision, and a higher than normal incidence of "halos" and glare as a result. In the past, this has been one of the biggest drawbacks to conventional laser correction surgery. Wavefront Optimized™ technology built into the ALLEGRETTO WAVE® addresses this limitation.

Better Night Vision and Glare Control

Los Angeles Lasik Dr. Andrew Caster informs us that at night and in dark conditions, the pupil becomes larger to permit the maximum amount of light to enter the eye. Laser eye correction needs to take this fact into account. If the optical zone is smaller than the size of the pupil at its largest, there is a good chance that the patient will experience poor night vision or problems with glare and halos around bright objects such as oncoming headlights. ALLEGRETTO WAVE® is able to produce a larger optical zone, virtually eliminating glare and night vision problems associated with older generation lasers.

Clinical Results

When it was approved in 2003 as the first new laser in five years, the FDA granted the ALLEGRETTO WAVE® the widest approval range ever initially given to a new laser for both myopic and hyperopic vision correction. Since then, Beverly Hills Lasik surgeons have consistently seen astoundingly positive results.

•At one year after treatment, more than 93% of patients said they saw at least as well as or better than they had with glasses or contacts before treatment.

•Following Lasik eye surgery Beverly Hills patients (more than 98%) achieved 20/40 vision one year after treatment; 20/40 is the level of visual acuity required to pass most driving tests.

•Nearly 60% of near-sighted patients achieved 20/16 vision after one year of treatment.

•Both near- and far-sighted patients reported an improvement in their reaction to bright lights and night driving glare after ALLEGRETTO WAVE® treatments. In addition, near-sighted patients reported an improvement in sensitivity to light.

•Predictable results are the norm for the ALLEGRETTO WAVE® . More than 90% of patients achieve refraction within 1 diopter of their target correction.
