Abstract
A Slit-lamp-or-Microscope-Integrated-OCT-Refractometer system includes an eye-visualization system, configured to provide a visual image of an imaged region in an eye; an Optical Coherence Tomographic (OCT) imaging system, configured to generate an OCT image of the imaged region; a refractometer, configured to generate a refractive mapping of the imaged region; and an analyzer, configured to determine refractive characteristics of the eye based on the OCT image and the refractive mapping, wherein the refractometer and the OCT imaging system are integrated into the eye visualization system.

A method for determining refractive characteristics of an eye, comprising:
- receiving, from an Optical Coherence Tomographic (OCT) imaging system, OCT image data of an imaged region of the eye;
- receiving, from a refractometer, refractive mapping data of the imaged region;
- registering, by a processor configured to execute optical analytic software, the OCT image data and the refractive mapping data;
- combining, by the processor, the OCT image data and refractive mapping data;
- and
- executing, by the processor, optical ray tracing software to determine the refractive characteristics of the eye based on the combined OCT image data and refractive mapping data;
- and
- displaying biometric information indicating the determined refractive characteristics of the eye.

- combine the OCT image data and refractive mapping data;
- and
- execute optical ray tracing software during a surgical procedure to determine one or more parameters of an eye-model based on the combined OCT image data and refractive mapping data;
- select, based on the determined parameters of the eye-model, characteristics of an Intra Ocular Lenses (IOL) to achieve an optical correction of the eye;
- and
- determine at least one of a recommended IOL optical power, a value and orientation of an astigmatism of a toric IOL, a multifocal characteristic, and a position of an IOL in a capsule of the eye to achieve the optical correction of the eye.
