US 12,178,751 B2 · Laser ophthalmic treatment system with time-gated image capture component and electronic display

Abstract

Technologies relate to imaging a treatment area during laser treatment using a time-gated image capture device and an electronic display. During laser treatment, a physician may monitor a treatment area to ensure efficacy and to prevent over-treatment. Light reflected from the area that includes the treatment area may be detected by an image capture component and converted to a signal. An image processor may then generate image data based on the signal and provide the image data to be displayed on an electronic device. A gating component may send instructions to the image capture component and/or the image processor to prevent inclusion of light from one or more laser pulses generated during treatment. Excluding light from the laser pulses may prevent glare in captured images for allowing a monitoring physician to safely and accurately monitor the treatment area.

Dependent claims

An apparatus provided for imaging a treatment area of an eye undergoing laser treatment, the apparatus comprising:

a treatment system configured to direct one or more laser pulses towards the treatment area of the eye;
an imaging system comprising at least one image capture component configured to:
detect light reflected from an area that includes the treatment area;
generate image data related to the treatment area based on the light reflected from the area that includes the treatment area, wherein generation of the image data is time-gated to exclude light reflected from the area that includes the treatment area during a time period in which the one or more laser pulses directed by the treatment system are incident on the treatment area;
and
provide the image data to be displayed on an electronic display to present an image of the treatment area during the laser treatment;
and
a controller communicatively coupled to the image capture component, the controller configured to control performance of operations by the image capture component based on a comparison of an intensity of the light reflected from the area with a particular threshold.

5 more elements

An imaging system for imaging a target area of an eye undergoing laser treatment, the imaging system comprising:

a lens configured to receive light reflected from the target area in response to one or more laser pulses being directed towards the target area by a laser source communicatively coupled to the imaging system;
an image sensor configured to detect and convert the light reflected from the target area to a signal;
an image processor configured to:
generate image data based on the signal;
provide the image data to be displayed on an electronic display to present an image of the target area during the laser treatment;
and
a gating component configured to determine a time period in which the one or more laser pulses directed by the laser source are incident on the target area based on a comparison of an intensity of the light reflected from the target area with a particular threshold and control a time-gating of the imaging system such that the image data excludes light reflected from the target area during the time period.
