Abstract
Deconvolution systems and methods based on cornea smoothing can be used to obtain an ablation target or treatment shape that does not induce significant high-order aberrations such as spherical aberration. Exemplary ablation targets or treatment shapes can provide a post-operative spherical aberration that is equal to or below a naturally occurring amount of spherical aberration.
Claims16
A computer program product for determining a vision treatment for an eye of a patient, the computer program product embodied on a non-transitory tangible computer readable medium, comprising:
- computer code for receiving an original target profile for the eye of the patient;
- computer code for convolving the original target profile with a spatial domain kernel filter so as to obtain a convolved profile, wherein the spatial domain kernel filter is based on an inverse Fourier transform of a Fourier domain noise filter;
- and
- computer code for determining the vision treatment based on the convolved profile.
