Systems and methods analyze, diagnose, and/or treat a patient's eye usingmodified forms of the point spread function ("PSF") tailored to the visionsystem. Factors that alter perception of visual aberrations can be includedand/or volumetric point spread functions calculated, often using point spreadfunction calculations throughout a range of optical distances to more fullyindicate 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 visualresponse, Stiles-Crawford effects, and/or non-linearity of retinal response.The perceived point spread function can offer objective confirmation of thepatient's visual perception, allow a treating physician to see a closerapproximation of what the patient sees, indicate the scale and significance ofwavefront aberrations, and/or show which aberrations affect vision and whichdo not.
