New Vision Laser Center is now offering All-Laser LASIK!
New Vision Laser Center is proud to offer All-Laser LASIK. During the LASIK procedure a thin flap is created in the cornea that is lifted up and folded back to expose the interior surface of the cornea for treatment. Unlike traditional LASIK that uses a mechanical microkeratome to create the flap, LASIK is performed using a femtosecond laser for this step. Both methods are very effective, consistently achieving excellent results.
Q: What is the difference between all-laser LASIK and traditional LASIK?
A: The difference between these procedures lies in the creation of the corneal flap. Before the laser treatment can be applied to reshape your cornea and correct your vision, a flap is created in the cornea that can be folded back and out of the way during the treatment. Once reshaping of the cornea is completed, the flap is then gently repositioned and adheres almost immediately without the use of stitches. In traditional LASIK this flap is created using a mechanical device called a microkeratome. With all-laser LASIK, the flap is created using a femtosecond laser.
Q: Why The Ziemer Femtosecond Laser?
A: The Ziemer Flap Laser produces many more laser spots with less energy per spot than other such lasers. It also allows more precise focusing of the laser energy into the exact location in the cornea where the flap will be created. This means the flap is easily lifted and reduces certain complications that can affect other such lasers.
Q: Does all-laser LASIK provide better results than a microkeratome?
A: Contrary to popular belief, the results of traditional microkeratome and all-laser LASIK are virtually the same. Therefore our 20/20 or your money back commitment applies to both procedures.
Q: Is it necessary to have all-laser LASIK, or can I still have traditional LASIK?
A: While many patients prefer the use of all-laser LASIK, it is not necessarily the best option for everyone. For patients with special corneal characteristics, such as very flat, steep, or thin corneas, it can be a better option. If, however, you have normal corneal measurements and do not want the added expense of all-laser LASIK, traditional LASIK may be the best choice for you. It’s your choice, but we will assist in your decision.
The physicians and staff at New Vision Laser Center are dedicated to improving the quality of life of our patients through life-changing vision procedures, treatments and ongoing research. “Custom LASIK” or “Wavefront-Driven LASIK” is a recent advancement in laser vision technology that allows the surgeon to personalize the procedure and to potentially improve the already excellent results obtained with traditional laser vision correction. This procedure uses wavefront technology, which provides new diagnostic information previously unattainable.
Wavefront technology was first developed in 1978 by Josef Bille, Ph.D., director of the Institute for Applied Physics at the University of Heidelberg, to measure wavefront distortions that occurred when light traveling through the atmosphere entered a telescopic lens. This technology removed any visual distortion or aberrations from the atmosphere allowing astrophysicists to more accurately view images of the stars and planets.
It is now possible to utilize this technology to record detailed information about the visual characteristics of the eye. Unlike standard measuring devices such as corneal topography, which measure the front surface of the eye called the cornea, the wavefront scans the way the entire optical system processes light.
Wavefront analysis works by measuring the distortion or irregularities of the eye, known as higher-order aberrations. When a ray of light first enters the eye, it passes through the cornea to the lens and vitreous, ultimately reaching the retina. As it bounces off the retina and returns back through the cornea, the wavefront analysis detects and documents these distortions, which are unique to each individual. Because each patient has a unique visual optical system, the wavefront data has been likened to a fingerprint.
Once the wavefront data has been documented for an individual patient, the next step is to use this information to utilize the excimer laser to correct the higher-order visual aberrations. The surgeon can then determine what adjustments must be made to the corneal surface to produce a clear, crisp image for the unique individual needs of each patient. The use of wavefront technology to provide a more precise laser vision correction is known as, “Custom LASIK” or “Wavefront-Driven LASIK”. Early data suggests that the 5-10 percent of patients who demonstrate higher-order aberrations are the patients that will significantly benefit from Custom LASIK treatments. Other patients may benefit from Custom LASIK to a smaller degree.
Every major laser manufacturer is actively working to bring this technology to market. The VISX® laser utilizes The VISX® WavePrint™ System including the WavePrint Map, 3D ActiveTrak™ Eyetracker and Variable Spot Scanning (VSS™). The WavePrint™ Map (Figure 1.) is the diagnostic tool that documents the precise analysis of the unique visual system. The 3D ActiveTrak™ follows the tiny motions of the eye instantaneously and automatically in all three dimensions, repositioning the laser as the eye moves slightly to ensure accuracy. The VSS™ is an exclusive VISX® laser technology that allows for a larger treatment area than previously available. This offers the physician greater flexibility in developing a more personalized laser vision procedure, when pupil size may be a consideration.
Statements regarding the potential benefits of wavefront-guided LASIK (CustomVue) are based upon the results of a clinical trial. These results are indicative of not only the CustomVue treatment but also the care of the clinical physicians, the control of the surgical environment by those physicians, the clinical trial’s treatment parameters and the clinical trial’s patient inclusion and exclusion criteria. Although many clinical trial patients after the CustomVue procedure saw 20/20 or better and/or had or reported having better vision during the day and at night, compared to their vision with glasses or contact lenses before the procedure, your results may vary.
Only an eye care professional trained in laser vision correction can determine whether you are a suitable candidate for the CustomVue procedure. As with any surgical procedure, there are risks associated with the CustomVue treatment. Before deciding whether to have the CustomVue procedure, you should ask your doctor for and carefully review the Patient Information Booklet. It is important to discuss the risks associated with the procedure and any questions you may have about the procedure with your doctor.
