Wavefront refractive technology provides a unique fingerprint of the patient's vision that displays the refractive errors and aberrations of the eye. The Wavefront technology was originally pioneered for astronomy and physics in order to aid in reducing aberrations, or imperfections, in the optical systems of telescopes and laser devices. Today, this unique technology is used to obtain a diagnostic measurement that is up to 25 times more precise than standard vision tests, resulting in customized treatment and a higher quality of vision.

The architecture of your cornea will first be measured using the Orbscan. The Orbscan is a painless exam that measures 10,000 separate data points of the front and back surfaces of your cornea. For more than 10 years, the Orbscan has been the standard of care for identifying possible asymmetries of the cornea. The results of the Orbscan will help to determine if LASIK can help you.
The second test uses an instrument called the Zywave to measure the optics of your eye. Bausch & Lomb adapted this revolutionary technology from the world’s most powerful telescopes which are used to get a better image of the faintest points of light in the night sky. It has been carefully refined for use in the measurement of the eye’s tiniest imperfections and creates a precise, three-dimensional ”eyeprint”, or personalized map of your eye that will be used to design your unique treatment.
For many patients there are numerous reasons for poor vision. In a single eye, there may be several different types of visual imperfections and these imperfections are called aberrations. Aberrations are classified as lower-order aberrations and higher-order aberrations. In the past, doctors were only able to correct the lower order aberrations, such as nearsightedness, farsightedness, and astigmatism. Yet, these are not the only causes of problem vision. Higher order aberrations impact your vision as well, and cannot be corrected with glasses or contacts or even traditional LASIK Surgery. Today, new Wavefront Mapping technology is available that examines the entire optical system, allowing for higher order aberrations to be detected, measured and mapped. The ability to diagnose the higher order aberrations now leads to the ability to correct them resulting in Wavefront-guided customized LASIK. It is also likely that post-operative patients with residual refractive errors may benefit from a wavefront-guided enhancement in the future.
