Abstract
Devices, systems, and methods measure, diagnose, and/or treat one or both eyes of a patient. Adaptive optics systems (such as those having a deformable mirror) may be configured to an aspherical or multi-spherical presbyopia-mitigating prescriptive shape to allow objective and/or subjective measurements of a candidate prescription. A plurality of viewing distances allow subjective and/or objective evaluations of performance using a light spot or a test viewing image. Measurements of aberrations at selected viewing conditions (including distances and/or brightness) with correlating pupil sizes may also be provided. Wavefront measurement systems and methods may help position and isolate the eye from ambient light.
