Patent ID: 7832863

Claim:
A method for determining a lens wavefront, comprising: measuring a patient's wavefront to create a pupil aberration p (n, m); n , m = - L 2 , … ⁢ , L 2 , wherein the pupil aberration p (n, m) is represented on a grid, where n, m are indices of matrix elements, and L is the total number of pixels on a side of the grid, generating a plurality of corrected wavefronts a ij (n, m); where i, j are indices of i th horizontal and j th vertical positions, wherein each corrected wavefront in the i th and j th position, a ij (n, m), is expressed as a ij (n, m) p (n, m)+s(n+i, m+j), where s(n+i, m+j) is a lens wavefront in the (n+j) th horizontal and (m+j) th vertical position, wherein the pupil aberration p(n, m) and the lens wavefront s(n+i, m+j) are represented on a grid and i represents the i th horizontal position and j represents the j th vertical position on the grid; generating a function of the plurality of corrected wavefronts a ij ; determining a lens wavefront by optimizing the function of the plurality of corrected wavefronts a ij ; and producing a lens taking into account the lens wavefront.
