  • Patent number: 11931294
    Abstract: A treatment probe for treating an eye of a patient includes an elongate body that defines a handle and a treatment fiber that is housed within the elongate body. The treatment fiber is configured to deliver treatment light energy to the eye. A contact member is disposed on an end of the elongate body. The contact member has a contact surface for positioning on a surface of the eye, two side edges that are positioned on opposite sides of the contact surface, and a fluid channel. The contact surface conforms to the shape of the eye's sclera and the two side edges are shaped to direct fluid that is present on the surface of the eye toward the fluid channel when the contact member is moved laterally across the surface of the eye. The fluid aggregates within the fluid channel and contacts a distal end of the treatment fiber.

  • Publication number: 20230355441
    Abstract: An ophthalmic treatment system and method for performing therapy on target tissue in a patient's eye. A delivery system delivers treatment light to the patient's eye and a camera captures a live image of the patient's eye. Control electronics control the delivery system, register a pre-treatment image of the patient's eye to the camera's live image (where the pre-treatment image includes a treatment template that identifies target tissue within the patient's eye), and verify whether or not the delivery system is aligned to the target tissue defined by the treatment template. The control electronics control the delivery system to project the treatment light onto the patient's eye in response to both an activation of a trigger device and the verification that the delivery system is aligned. to the target tissue, as well as adjust delivery system alignment to track eye movement.

  • Patent number: 11690761
    Abstract: Systems, devices, and methods for treating a glaucomatous eye are provided. An amount of pulsed laser energy is delivered to the pars plana of the eye by a hand-holdable device which comprises a hand-holdable elongate member and a contact member disposed on an end of the elongate member. A contact surface of the contact member is placed in direct contact with the eye so that a reference edge of the contact member aligns with the limbus and a treatment axis defined by the elongate member is angularly offset from the optical axis of the eye. The amount of pulsed laser energy delivered is insufficient to effect therapeutic photocoagulation but is sufficient to increase uveoscleral outflow so as to maintain a reduction from pre-laser treatment intraocular pressure. Amounts of pulsed laser energy will be transmitted to a circumferential series of tissue regions of the eye.

  • Publication number: 20230141548
    Abstract: In some embodiments, an ophthalmic laser system may be provided that does not include a traditional laser console. Instead, the treatment device may be configured to house the treatment light source within the device handle. Additionally, in some embodiments, the handheld treatment device may include a user interface, such as dials and buttons, for adjusting various parameters of the therapeutic light. With certain embodiments, the self-contained handheld treatment device may be operated independent of an AC power source. For example, in some embodiments, the handheld treatment device may be battery powered. Additionally, the handheld treatment device may be disposable or may utilize replaceable distal tips in certain embodiments. Certain embodiments may be particularly designed for transscleral cyclophotocoagulation. Also, treatment guides are provided that may be configured to couple with a treatment device to align the device with a target tissue of the eye.

  • Publication number: 20220226151
    Abstract: In some embodiments, a system for providing a therapeutic treatment to a patient's eye includes a treatment beam source configured to transmit a treatment beam along a treatment beam path. The system further includes a processor coupled to the treatment beam source, the processor being configured to direct the treatment beam onto retinal tissue of the patient's eye and deliver a series of short duration pulses from the treatment beam onto the retinal tissue at a first treatment spot to treat the retinal tissue. In some embodiments, a pre-treatment evaluation method using electroretinography (ERG) data may be used to predict effects of treatment beams at different power values and to determine optimal power values.

  • Patent number: 11143828
    Abstract: An optical switch incorporated in a photomedical system, and a method of treating tissue using the optical switch for creating pulsed light. A light source generates an optical beam. An aperture element includes a light-transmitting portion and a light-blocking portion. An optical element such as a mirror, prism or lens directs the optical beam to the aperture element, wherein the optical element is movable for translating the optical beam across the light-transmitting and light-blocking portions of the aperture element, or changing its angle of incidence through the aperture to produce one or more pulses of light from the optical beam. A lens focuses the one or more pulses of the optical beam onto target tissue. A controller controls the movement of the optical element to produce the one or more pulses of light.

  • Publication number: 20210275829
    Abstract: A light based system for treating an eye includes a mask that is configured for positioning on the eye and a light source that is configured to deliver therapeutic light. The mask has an inner surface that is positionable against the eye and an outer surface that is opposite the inner surface. The mask is optically opaque to prevent transmission of light through the mask and the mask includes at least one transparent opening that allows transmission of light through the mask to target tissue of the eye posterior the transparent opening. The light source is positioned relative to the mask so that the delivered therapeutic light irradiates at least a portion of the mask and the transparent opening. Therapeutic light traverses through the transparent opening to the target tissue positioned posterior the transparent opening.
