Patent ID: 8740381

Claim:
A method for vision correction comprising the following steps: (a) acquiring wavefront measurements from an eye at a first pupil diameter d 1 , representing the wavefront measurements by Zernike coefficients, and providing one or more Zernike coefficients relating to the first pupil diameter d 1 in a vector Z 1 ; (b) multiplying the vector Z 1 with a conversion matrix M and outputting the result into a vector Z 2 containing extrapolated Zernike coefficients relating to the second pupil diameter d 2 , wherein the first pupil diameter d 1 is incorporated into the conversion matrix M and d 2 is greater than d 1 ; (c) using the extrapolated Zemike coefficients to determine a vision correction treatment; (d) ordering the Zernike coefficients relating to the first pupil diameter d 1 into the vector Z 1 using a permutation matrix P, prior to the step of multiplying the vector Z 1 with the conversion matrix M; and (e) applying the treatment to the eye.
