摘要：
Embodiments of the present invention encompass systems and methods for generating a vision treatment target for an eye of a patient. Exemplary techniques can involve obtaining a wavefront measurement for the eye of the patient, processing the wavefront measurement, using a low pass filter, to obtain an ocular wavefront, and generating the vision treatment target based on the ocular wavefront. In some cases, the wavefront is processed by applying a Fourier transform to the wavefront measurement to obtain a Fourier spectrum of the wavefront, convolving, in the Fourier domain, the Fourier spectrum of the wavefront and the low pass filter to obtain a Fourier spectrum convolution result, and applying an inverse transform to the convolution result to obtain the ocular wavefront. The ocular wavefront can represent a low pass filtered version of the wavefront measurement, such that high spatial frequency features present in the wavefront measurement are not present in the ocular wavefront
