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.
Claims19
A therapeutic laser delivery system, the system comprising:
- a therapeutic laser configured to generate a therapeutic laser light for passing through a therapeutic laser delivery optical path;
- a spatial light modulator (SLM) device arranged in the therapeutic laser delivery optical path and configured to modulate the therapeutic laser light to:
- split the therapeutic laser light into a plurality of therapeutic laser light beams;
- and
- simultaneously deliver the plurality of therapeutic laser light beams to a plurality of target locations in an eye,
- wherein the SLM device is configurable to control modulation of the therapeutic laser light and the plurality of target locations of the eye that the plurality of therapeutic laser light beams is simultaneously delivered to;
- a targeting laser configured to generate a targeting laser light for passing through a targeting laser delivery optical path,
- wherein the SLM device is arranged in the targeting laser delivery optical path and further configured to modulate the targeting laser light into a plurality of targeting laser light beams, and
- wherein the SLM device is configurable to control modulation of the therapeutic laser light in order to correct for a difference between a target location of the plurality of target locations and a determined treatment location;
- and
- a processor for executing software instructions to configure the SLM device and set the plurality of target locations of the eye that the plurality of therapeutic laser light beams is simultaneously delivered to.

- and
- simultaneously deliver the plurality of laser light beams to a plurality of target locations in the eye,
- wherein the SLM device is configurable to control modulation of the received laser light and the plurality of target locations of the eye that the plurality of laser light beams are simultaneously delivered to;
- and
- the processor for executing software instructions to configure the SLM device and set the plurality of target locations of the eye that the plurality of laser light beams are simultaneously delivered to;
- operating the targeting laser to generate the targeting laser light;
- and
- controlling the SLM device to modulate the targeting laser light to split the targeting laser light into a plurality of targeting laser light beams to be simultaneously delivered to the determined-target locations.
