Abstract
A therapeutic laser for use in treating ophthalmological conditions can be modulated by a spatial light modulation device in order to focus the therapeutic laser on a plurality of target locations simultaneously.
Claims20
A therapeutic laser delivery system for ophthalmology comprising:
- an imaging system comprising at least one of:
- a scanning laser ophthalmoscopy (SLO) system comprising a SLO detector and a SLO light source, wherein the SLO light source is configured to generate light for passing from the SLO light source through an SLO optical pathway for SLO imaging, or an optical coherence tomography (OCT) system comprising an OCT detector and an OCT light source, wherein the OCT light source is configured to generate light for passing from the OCT light source through an OCT optical pathway for OCT imaging;
- a therapeutic laser configured to generate a therapeutic laser light for passing through a therapeutic laser delivery optical path and delivering at least a portion of the therapeutic laser light to an ophthalmological target;
- a spatial light modulator (SLM) device arranged in the therapeutic laser delivery optical path to modulate the therapeutic laser light, wherein the SLM device is configured to split the therapeutic laser light into a plurality of therapeutic laser light beams for simultaneous delivery of the therapeutic laser light beams to a plurality of target locations;
- and
- at least one processor for determining the plurality of target locations and controlling the SLM device to modulate the therapeutic laser light for treatment of floaters in a vitreous humour of the ophthalmological target,
- wherein the SLM device is configured to control one or more characteristics of the therapeutic laser light to adapt the therapeutic laser light for increased coverage of or application to the floaters for treatment in the vitreous humour, the one or more characteristics being at least one of:
- a shape, a lightwave phase, a lightwave polarization, a wavefront tilt, a diffraction, a wavefront helicity, and an orbital angular momentum order.

A method of targeting a therapeutic laser on an ophthalmological target comprising:
- determining a plurality of target locations for receiving targeting laser light beams;
- controlling a spatial light modulation (SLM) device to split a targeting laser light into a plurality of targeting laser light beams and simultaneously deliver the targeting laser light beams to the plurality of determined target locations;
- capturing an image of the plurality of targeting laser light beams delivered to the plurality of determined target locations;
- comparing locations of the plurality of targeting laser light beams captured in the image to the plurality of determined target locations;
- controlling the SLM device based on feedback from the comparing of the locations of the plurality of targeting laser light beams captured in the image to the plurality of determined target locations;
- delivering a plurality of therapeutic laser light beams to the plurality of target locations, wherein the SLM device is configured receive therapeutic laser light and to split the therapeutic laser into the plurality of therapeutic laser light beams.
