The WaveScan WaveFront System is an ophthalmic diagnostic instrument that measures the refractive error and wavefront aberrations of the human eye using a Hartmann-Shack wavefront sensor. The measurements can be used to determine regular (sphero-cylindrical) refractive errors and irregularities (aberrations) that cause decreased or blurry vision in the human eye. The WaveScan software uses the information to create a custom tailored correction map for the unique characteristics of each individual eye.
WaveScan technology was originally developed for use in high-powered telescopes to reduce distortions when viewing distant objects in space. This technology has now been applied to laser vision correction, measuring imperfections in the eye never before measured using standard methods for glasses and contact lenses. WaveScan-based digital technology identifies and measures imperfections in your eyes 25 times more precisely than standard methods. The powerful WaveScan software translates the information into a set of CustomVue treatment instructions for the laser. These digital treatment instructions are then transferred to the laser, driving a new level of precision and accuracy.
Until now, eye doctors were forced to practice one-size-fits-all vision. An off-the-shelf lens can correct your vision fairly well, but it is not uniquely tailored to your fingerprint of vision. Now, with WaveScan technology, your eye doctor can custom tailor a correction for the unique characteristics of your vision.
The WaveScan WaveFront System provides:
Fourier-based wavefront algorithms:
Acuity Maps®: Chart the optical aberrations of the eye.
Difference Maps: Track the changes of the eye for pre-op and post-op comparisons.
Point Spread Function (PSF): Demonstrates how a patient would see a point source of light
