When someone decides that they want LASIK, they rarely consider the type of laser that will be used to fix their vision. While it is true that there are many different lasers used by ophthalmologists to correct myopia or hyperopia, you may want to know a little about the one that will be used on your eyes, especially if you are concerned about some of the side effects on your night vision that you may have heard about. Halos and glare are extremely rare, but they have a bothersome effect on LASIK patients. One of the latest generation lasers that can solve these types of issues is called the Allegretto Wave excimer laser.
The Food and Drug Administration approved the Allegretto Wave laser in 2003 for use with LASIK surgery. Allegretto Wave uses PerfectPulse Technology. This technology basically means that the laser is calibrated for your individual eye and does not act as a blanket solution for all eyes. Think of your eye like a fingerprint: no one else has your exact eye. One of the problems with older lasers is that they may have acted as a one-size-fits-all solution. It is here where some of the problems with LASIK have occurred. With Allegretto Wave’s PerfectPulse Technology, the beam’s pulse hits your eye exactly where it should. Checkpoints are made even as the pulse works at 200 times per second. If an adjustment is needed, this can be done, if your eye moves out of the beam’s range, for example.
Allegretto Wave also uses something called wavefront-guided technology. This essentially creates a map of your eye. Because no two eyes are the same, the eye’s “cartography” is important at the microscopic level. Since the laser will be sculpting your cornea, it is necessary that a map be created so that the 200 pulses per second know where they’re going. When this is done, more corneal tissue is preserved.
One of the unique features about Allegretto Wave is that it is able to read a large optical zone. This is the zone of the pupil that is affected by night vision (the more light needed in the eye, the larger the pupil zone). Through reading and mapping the entire optical zone, the chances of halos and glare are nearly eliminated.

Excimer lasers for use in LASIK surgery have come a long way. The way that technology continually advances gives some of them an edge over others. One of these, the Allegretto Wave excimer laser, helps to reduce the chance of halos and glares with night vision as it corrects myopia, hyperopia, and astigmatism. Many people may want to correct their vision with LASIK, but are nervous about the side effects they’ve heard about in the media. Two of these, halos and glare, affect night vision and can make driving difficult. When the Allegretto Wave was approved by the Food and Drug Agency in 2003, this was one of its listed benefits. There are several other advantages of this next generation laser.
Advantages of Allegretto Wave
- Wavefront-guided technology – This technology is not only found with the Allegretto Wave excimer laser, but is extremely important in LASIK surgery. Wavefront-guided technology creates a map at the microscopic level for your custom LASIK vision correction. This helps to reduce and eliminate any aberrations that might add to the risk of night vision-harming side effects like glare or halos.
- PerfectPulse Technology – Extremely reliable eye tracking and speed are used with PerfectPulse Technology. If your eye moves out of the range of the beam, it will stop and wait for your eye to return to its proper location. The controlled pulse assures the clearest vision possible.
- Speed – Moving at 200 times per second, the pulse of the beam knows exactly where to go at each step. Due to the speed, LASIK surgery with Allegretto Wave takes as long as pouring a cup of coffee. This also helps to reduce post-operative complications.
- Cross Line Projector – A red cross line lets your ophthalmologist know exactly what the alignment of the eye is and where the beam will pulse. This allows for an extra layer of security in the successful outcome of your LASIK surgery with Allegretto Wave.
Technology used in the office of the ophthalmologist today are some of the most up-to-date and cutting edge available. Not only can your vision be perfected, your night vision will not suffer any degradation. Patient satisfaction with Allegretto Wave has been close to 100%.

Are you tired of wearing glasses or do you feel the glasses do not suit your style or give you an elderly look and have contact lens intolerance, or do you feel that it is difficult to manage contact lenses? Do you like activities such as outdoor sports like golf, football, water sports or hiking but are inhibited to enjoy those due to glasses or lens wear?
The perfect and the only answer to all these problems is LASIK surgery for eye sight correction.
LASIK stands for LASER IN-SITU KERATOMILEUSIS. It is a new form of laser surgery that is capable of correcting a wide range of glass numbers. The procedure uses a computer-controlled excimer laser to reshape the cornea to correct vision. The laser reshaping is done under a protective flap of tissue to promote a very rapid recovery of vision and minimize discomfort.
Light falling on the cornea [the front surface of the eye] has a smooth curvature- referred to as a “wave front”. As this smooth wave front shape courses through the various optics of the eye, ocular aberrations (imperfections) are induced. It results in an irregular wave front curvature reaching the retinal surface, which degrades the retinal image quality. An aberration-free eye would result in a smooth wave front image on the retinal surface. Wave front-guided customized LASIK, also referred to as “customized ablation” or custom LASIK performs corrections based on individual wave front measurements.
Custom LASIK or Custom Wave front LASIK, treatment replaces “one treatment fits all” with a procedure that is tailored to the individual eye. While standard laser eye treatment (without Wave front guidance) gives very high quality results for the majority of patients, many peoples’ eyes are not ‘standard’. Their eyes might require a specially tailored treatment.
Thus, any individual above 18 years of age, who does not have unstable spectacle power, is not pregnant or nursing and not suffering from uncontrolled diabetes or vascular disease, is a good candidate for the surgery and can easily get his vision corrected through the wonderful LASIK surgery.
