US 2019/0167472 A1 · Multiple spot photomedical treatment using a laser indirect ophthalmoscope

Abstract

A laser indirect ophthalmoscope (LIO) apparatus for photomedical treatment and/or diagnosis is presented. The LIO apparatus allows multiple spot ophthalmic surgery to be performed in a wider range of patient positions and less intrusively than currently available methods. The LIO apparatus utilizes a separate or integral beam multiplier that generates one or more optical beams via spatial and/or temporal separation, and an optical system that conditions and directs the one or more optical beams to a target to form a pattern. The LIO apparatus includes a headset, and is therefore wearable by the user (e.g., a physician).

Dependent claims

A photomedical system for treating eye tissue comprising:

a treatment light source configured to generate a treatment light beam;
a headset designed to be worn by a user, wherein the headset includes:
an optical input configured to receive the treatment light beam;
a beam multiplier configured to receive the treatment light beam and generate a plurality of treatment sub-beams by spatial separation of the treatment light beam;
and
a moveable mirror configured to receive the plurality of treatment sub-beams and project the plurality of treatment sub-beams on the eye tissue in the form of a treatment pattern;
and
control electronics configured to cause the treatment light source, the beam multiplier, and the moveable mirror to automatically form the treatment pattern on the eye tissue.
