Applications: Wavefront sensors are used to diagnoses and correct the optical defects in the eye. This technology increases dynamic range of a conventional wavefront sensor without sacrificing measurement sensitivity for the eye and optical testing.Advantages: The increased dynamic range of wavefront sensor enhances diagnosis and correction of optical defects in highly myopic patients or patients with abnormal corneas who have very large amounts of optical defects. This is accomplished using software rather than modifying the existing wavefront sensor hardware and the software algorithm can be easily combined with existing wavefront analysis software.
