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%.

Thanks to advances in laser technology and medical training, people who suffer from certain eye ailments can finally get relief from always wearing glasses. Previously, laser-assisted in situ keratomileusis or <a href=http://www.horizoneye.com/index.cfm/fuseaction/site.content/type/24693.cfm>LASIK</a> was available only to the very wealthy. Now through greater competition and lower prices it is now widely available to the masses. If you are ready to give up your glasses or <a href=http://www.horizoneye.com/index.cfm/fuseaction/site.content/type/24742.cfm>contact lenses</a> for the freedom of good eyesight, now is a great time to explore the benefits of LASIK eye surgery.
LASIK eye surgery is a common treatment for refractive errors of the eye, including:
- Myopia (nearsightedness)
- Hyperopia (farsightedness)
- Astigmatism
Treating and Myopia with LASIK
Approximately 30 percent of the population experience nearsightedness, which is traditionally treated with prescription glasses or contact lenses. In a normal eye, light passed through the cornea and the lens of the eye, converging on the retina, recording a sharp clear picture that your brain interprets. Myopia is a condition resulting from one of two conditions:
- Elongated eye
- Steep cornea
With these conditions, the light converges in front of the retina, causing blurry images for objects at a distance. Prescription glasses are used to correct the refraction and return the focus to the proper location on the retina. Using this same theory, LASIK corrects the focus in the same way be reshaping the cornea to do the same thing.
Treating Hyperopia with LASIK
Hyperopia is basically the opposite of myopia. Instead of the light refracting and focusing in front of the retina, the convergence occurs at a point behind the retina. Approximately 40% of adults have hyperopia to some degree. Conditions that lead to hyperopia are:
- Shortened eye
- Shallow cornea
Treating Astigmatism with LASIK
A typical cornea is rounded like a ball. With astigmatism, the cornea is shaped like a football or has a wrinkle that causes the light to refract erratically.
- In a regular astigmatism, the foci are 180 degrees opposite along the vertical or horizontal axis.
- Irregular astigmatism, which is typically caused by outside forces, disease, or injury, may have one or more foci in various locations that are asymmetrical.
How LASIK Treatment Works
LASIK uses the same theories for vision correction that are used in glasses and contacts. The difference is that the laser directly reshapes the cornea to correct the refraction.
During the procedure:
- A flap is made at the front of the cornea and folded back
- The laser, guided by a computer mapping is makes precise cuts in a predetermined pattern to reshape the cornea
- The flap is replaced and also acts as a natural bandage over the corrected cornea
If you suffer from myopia, hyperopia with or without astigmatism and you want to get rid of eyeglasses or contact lenses, you should consider LASIK eye surgery. To find a Charlotte LASIK eye doctor please visit the website of Horizon Eye Care today.
