ABSTRACT:
Systems and methods analyze, diagnose, and/or treat a patient's eye using modified forms of the point spread function (“PSF”) tailored to the vision system. Factors that alter perception of visual aberrations can be included and/or volumetric point spread functions calculated, often using point spread function calculations throughout a range of optical distances to more fully indicate the variation in visual perception of optics at different distances. A variety of visual affects of the human optical system can be simulated, analyzed, and modeled, including: single versus multiple wavelength sources, chromatic aberrations, retinal resolution, wavelength-dependent visual response, Stiles-Crawford effects, and/or non-linearity of retinal response. The perceived point spread function can offer objective confirmation of the patient's visual perception, allow a treating physician to see a closer approximation of what the patient sees, indicate the scale and significance of wavefront aberrations, and/or show which aberrations affect vision and which do not.
