Wavefront Technology (Custom LASIK Eye Surgery)
LASIK in New York City is a popular elective vision care procedure that can possibly reduce your dependence on glasses and contact lenses. For many patients, Dr. Moadel feels that CustomVue technology (also referred to as Wavescan technology) offers his patients the best option for a safe and excellent visual outcome. Wavefront Technology is also commonly called Custom LASIK eye surgery. Essentially, wavefront technology involves taking a "digitized" image of the patient's eye including the corneal contour. These measurements are made at a computer station known as the wavescan. A wavescan image is analogous to taking a digital photograph of the eye. These digital images are then transferred to the laser where a unique treatment can be created tailored to the patient's eye shape.
Wavefront technology enables the physician to measure and correct unique imperfections in a patient's eye. Many of these subtle imperfections could not be measured nor corrected before the introduction of this technology. A six-month evaluation has shown that Customvue improves sharpness of vision and decreases possible nighttime side effects.
Wavefront technology was initially developed under the guidance of NASA and was applied to astronomy and physics to aid in reducing aberrations or imperfections in the optical systems of telescopes and laser devices. This technology was then tested, researched and applied to optical imperfections of the human eye. The technology itself works to measure higher order imperfections of the eye. Conventional LASIK did a great job at correcting lower order aberrations (nearsightedness, farsightedness, and astigmatism), however, did not address imperfections known as higher order aberrations. Higher order aberrations are imperfections that cannot be corrected with glasses, contacts or even traditional LASIK surgery. Wavefront technology addresses these types of visual imperfections.
However, the decision of whether or not to use CustomVue technology is complex and varies from individual to individual. During your evaluation here at our center in New York, you will receive a thorough eye examination, during which Dr. Moadel can direct you to which treatment would be best for your individual eyes.
How Does Wavefront Technology Work?
The Custom LASIK Procedure
Light from the wave scanning machine is projected into the eye on wavefront sheets. These wavefront sheets enter the eye, pass through the entire optical system and are then reflected back. The information obtained in these wavefront measurements will be utilized by the ophthalmologist to develop a more custom version of LASIK eye surgery. Once this wavefront information has been collected the next step is to use this information with the excimer laser to correct the higher-order visual aberrations. The LASIK surgeon can then determine what adjustments should 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.
Wavefront technology is recent technology that has helped reduce higher order aberrations. However, this technology is not broadly superior for all patients. Based on his expertise and dedication to LASIK over a decade, Dr. Moadel can determine which method will result in the best and safest visual outcome for his patients.
