A system for determining a vision treatment for an eye of a patient is provided which comprises a memory configured to store programmed instructions and data. The system also comprises a processor in communication with the memory. The processor is configured to receive an original target profile for the eye of the patient. The processor is also configured to obtain a cut-off spatial domain kernel filter and convolve the original target profile with the cut-off spatial domain kernel filter to provide a convolved target profile. The processor is further configured to determine the vision treatment based on the convolved target profile.
