US Patent 12059206 Feedback-assisted system for nonpharmacologic constriction of a pupil

An ophthalmic stimulator for temporarily constricting a pupil of an eye comprises an irradiation control system, having a feedback system, to generate an irradiation control signal using a feedback of the feedback system; an irradiation source, coupled to the irradiation control system, to generate an irradiation; and an irradiation delivery system, having a targeting system and coupled to the irradiation control system, to receive the irradiation from the irradiation source, and to direct a patterned irradiation in a pattern to a treatment region of an iris of the eye using the targeting system; wherein the irradiation control system controls at least one of the irradiation source and the irradiation delivery system with the irradiation control signal so that the patterned irradiation causes a temporary constriction of the pupil, without causing a permanent constriction of the pupil.
