A laser probe includes a cannula, at least one optical fiber positioned within the cannula, and a lens positioned within the cannula at a distal end of the fiber. The lens is adapted to receive a laser beam from the optical fiber at a proximal end of the lens and to transmit the laser beam towards a distal end of the lens. The laser probe includes an optical element configured coupled to the cannula by a brazed joint and to receive the laser beam from the distal end of the lens and emit the laser beam from the probe. The brazed joint may form a hermetic or liquid-tight seal between the optical element and the cannula.

Systems and methods for creating multi-spot laser light beams, multiplexing an illumination light and the multi-spot laser light beams, and delivering the multiplexed light to a surgical handpiece via a multi-core optical fiber cable.

[Object] To provide a control apparatus, a control method, a program, and a control system by which precise control can be made efficiently.

[Solving Means] In order to accomplish the above-mentioned objective, a control apparatus according to an embodiment of the present technology includes an acquisition unit and a control unit. The acquisition unit acquires situation information relating to surgery, the situation information being based on a captured image relating to a patient eyeball, the captured image being captured by a surgical microscope. The control unit controls a control parameter relating to a treatment apparatus on the basis of the situation information, the treatment apparatus being used for the surgery. Accordingly, precise control can be made efficiently. Moreover, the precision of predicting a dangerous situation is enhanced by recognizing a situation of the surgery in image recognition.

A retinal phototherapy or photostimulation system includes a laser console generating at least one treatment beam having parameters to photostimulate or treat, while not permanently damaging, a retinal target tissue. The parameters of the at least one treatment beam are fixed so as not to be alterable by a medical provider. A projector or camera projects the at least one treatment beam onto at least a portion of the retina, and a scanning mechanism controllably directs the at least one treatment beam to treatment areas of the retina.

At least one pulsed light beam is applied to eye tissue to raise the temperature of the eye tissue to photostimulate the tissue. The at least one light beam has parameters of wavelength, duty cycle, power and pulse train duration selected to achieve a therapeutic or prophylactic effect while not permanently damaging the eye tissue. The eye tissue photostimulation improves ocular health and function and slows or prevents disorders associated with a normally aging eye.

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores, a cladding surrounding the plurality of cores, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding, and a coating surrounding the cladding, a distal end free of the coating and having a reduced diameter. The MCF also comprise an annular gap formed between the distal end of the MCF and the inner surface of the cannula, wherein the concentricity of the distal end of the MCF with the inner passage of the cannula is maintained.

The invention concerns a dye for use in a method of photoporation of the inner limiting membrane (ILM) of an eye in a subject. Preferably, the method comprises: administering the dye to the vitreous chamber of the eye of the subject; and irradiating at least part of the ILM of the eye of the subject, thereby photoporating at least part of the ILM in the subject. The invention further relates to a dye and optionally a therapeutic agent for use in a method of treating a retinal disease or a choroidal disease of an eye in a subject.

Systems and methods for creating multi-spot laser light beams, multiplexing an illumination light and the multi-spot laser light beams, delivering the multiplexed light to a surgical handpiece via a multi-core optical fiber cable, and delivering the multiplexed light onto patient anatomy.

Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

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.
