US 2020/0345449 A1 · NEAR INFRARED ILLUMINATION FOR SURGICAL PROCEDURE

Abstract

Systems, devices, and methods for surgical illumination and imaging of ophthalmologic structures within a human eye are disclosed. In various embodiments, an emitter, imaging sensor, and a system control image processor are configured to irradiate ophthalmologic structures with near infrared light, detect near-infrared scatter from the irradiated ophthalmologic structures and visible light in real-time and generate or otherwise cause an image to be displayed on the user display that includes the detected near-infrared scatter from the irradiated ophthalmologic structures displayed in real-time. In one or more embodiments, the image is a virtual image of the irradiated ophthalmologic structures generated at least based on near-infrared light scattering coefficients of the irradiated ophthalmologic structures. In certain embodiments, the image displayed on the user display includes the detected near-infrared scatter from the irradiated ophthalmologic structures overlaid on a real-time view from a surgical microscope.

Dependent claims

A system for surgical illumination and imaging of ophthalmologic structures within a human eye, said system comprising:

an emitter configured to irradiate ophthalmologic structures with near infrared light;
an imaging sensor configured to receive and detect near-infrared scatter from the irradiated ophthalmologic structures and visible light in real-time;
and
a system control and image processor device comprising a processor, an electronic storage location operatively coupled with the processor, a user display, and processor executable code stored on the electronic storage location and embodied in a non-transitory computer readable storage medium, the surgical microscope, emitter, and imaging sensor communicatively coupled together, the imaging sensor configured to transmit the detected near-infrared scatter and visible light to the system control and image processor device,
wherein the processor executable code comprises machine-readable instructions, that when executed by the processor, causes an image to be displayed on the user display that includes the detected near-infrared scatter from the irradiated ophthalmologic structures displayed in real-time.

2 more elements

A surgical illumination device for ophthalmologic structures configured to be placed on an eye, the device comprising:

an annular base portion, the annular base portion having an L-shape with a first part of the L-shape defining an outward sidewall portion and outward sidewall and a second part of the L-shape extending radially inwardly relative to the outward sidewall portion to define a floor portion and a radially inward sidewall that rests against the sclera when placed on an eye;
an annular scleral support having a generally frusto-conical shape that extends from a more radially inward top portion to a more radially outward bottom portion, the scleral support having an interior sidewall that rests on against a sclera when placed on an eye and an exterior sidewall, the scleral support assembled with the annular base portion at a radially most inward portion of the base portion to form a generally flush interior sidewall surface with the interior sidewall and the radially inward sidewall resting against the eye;
an annular illumination portion includes one or more light emitting devices embedded therein and connected to a power source/control signal via a cable, wherein the assembled annular base portion and scleral support defining an interior space for placement of an annular illumination portion.
wherein, the scleral support is composed of a clear or semi-clear material and wherein in operation light emitted from the embedded light emitting devices illuminate or transilluminate tissue of the eye.
