摘要： The present invention provides methods, systems and software for scaling optical aberration measurements of optical systems. In one embodiment, the present invention provides a method of reconstructing optical tissues of an eye. The method comprises transmitting an image through the optical tissues of the eye. Aberration data from the transmitted image is measured across the optical tissues of the eye at a first plane. A conversion algorithm is applied to the data, converting it to corrective optical power data that can be used as a basis for constructing a treatment for the eye at a second plane.

摘要： 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.
