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. The WaveScan WaveFront™ System's digital technology identifies and measures imperfections in your eye 25-times more precisely than standard methods.

The VISX™ Fourier wavefront upgrade has the ability to capture wavefront information on larger pupil patients and utilize this data for optical zone treatments out to 7 mm. Transition zones continue to be adjustable out to 9.5 mm. The WaveScan WaveFront System utilizes the patient's corneal K-values and wavefront measurement to create the optimal corneal shape for each individual, whether it be prolate, oblate, or spherical.

The WaveScan WaveFront System provides:

• Fourier-based wavefront algorithms
  • Fourier delivers the highest resolution available of the wavefront error
  • Uses more data points to derive the optimal shape
  • Uses all data from any shape of pupil
  • Accurately reconstructs all peripheral data
  • Captures higher and lower order aberrations up to 7 mm diameter pupil
• WaveScan acuity maps: Chart the optical aberrations of the eye
• Difference maps: Track the changes of the eye for preop and postop comparisons
• Point spread function (PSF): Demonstrates how a patient would see a point source of light
