Abstract: Provided herein are methods and systems for measuring an optical quality of an eye that is based on laser ray tracing. Generally, the method utilizes steps of probing the human eye sequentially in time with one or a plurality of laser beams in a set of points within an aperture of the eye, detecting the projections of the laser beam reflected and scattered from the retina and processing the detected images of the laser spots. Components of the system include, but are not limited to, a laser with a two-axis acousto-optical deflector and with a two-output generator of digitally synthesized sinusoidal voltages in one embodiment, a collimating optical system, a conjugating telescopic system, a polarizing beam splitter, and first and second photosensitive detectors each of which are in operable communication with a processing unit. Another embodiment utilizes a multi-laser block which does not require laser beam scanning.

Abstract: The present invention is a predictive analytics method and system for the optimization of vision quality in a subject which uses at least one of an optical quality index of a total eye, an optical quality index of a cornea or a dysfunctional lens index as preoperative conditions input. The output is a type and at least one outcome of a procedure performed on an eye of the patient. A correlation between measured data of preoperative conditions from the cloud library and the input data of preoperative conditions for each component of pre-operative conditions is calculated to enable recommendations by a doctor.

The tool uses at least one of an optical quality index of a total eye, an optical quality index of a cornea or a dysfunctional lens index as preoperative conditions input into the tool. The output is a type and at least one outcome of a technology performed on an eye of the subject. A correlation between measured data of preoperative conditions from the cloud library and the input data of preoperative conditions for each component of pre-op conditions is calculated to enable recommendations by a doctor.

Abstract: Provided herein are methods for objectively determining a visual axis of an eye. An optical axis of a measuring instrument is aligned with an unambiguously determinable axis of the eye which is the pupillary axis crossing the vertex of an anterior surface of a cornea and perpendicular to the vertex. A wave front tilt of radiation of a set of narrow laser beams backscattered from the retina is calculated as a tilt component in a polynomial that describes the wave front. The visual axis is reconstructed from a set of chief rays exiting from the eye after crossing nodal points of the optical system of the eye.
