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.

The invention resides in a pattern laser comprising a plurality of laser devices each emitting a treatment laser beam into an optical fibre of an optical fibre bundle. An optical coupling module is associated with each laser device and each optical fibre for coupling a treatment laser beam into the associated optical fibre. A controller controls the operation of the laser devices by selectively turning on or off one or more of the laser devices so as to form a laser treatment pattern at an end of the fibre bundle away from the laser devices. A delivery system images the output from the fibre bundle to a treatment zone.

Ophthalmic phototherapy devices, systems, and treatment methods to expose an eye to selected multi-wavelengths of light to promote the healing of damaged or diseased eye tissue. The devices include a housing having an interior; an eyepiece disposed on the housing and configured and arranged for placement of an eye of the patient adjacent the eyepiece; a first light source producing a first light beam having a first therapeutic wavelength and disposed within the housing; a second light source producing a second light beam having a second therapeutic wavelength and disposed within the housing, where the second therapeutic wavelength differs from the first therapeutic wavelength by at least 25 nm.

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.

Photobiomedulation therapy (PBMT) can be applied to the eye to treat optical neuritis, a sign of multiple sclerosis (MS). The light of PBMT can be directed into the eye, regardless of the position of the eye, by a device that includes an array of light delivery devices and a heat sink lens. The device can be placed proximal to the eye to direct the light into the eye. The light can have one or more wavelengths from 400-1100 nm and can be applied in at least one of a pulsed operating mode, a continuous operating mode, and a super-pulsed operating mode through the light source device to the skeletal muscle. The light signal is applied for a time sufficient to stimulate a phototherapeutic response in the retina and/or the optic nerve. PBMT applied in this manner provides a noninvasive, safe and effective treatment for optic neuritis.

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.

A laser therapy device includes: a solid-state laser for a CW operation and including a pump source; and a controller for generating at least one first pulse of the laser in a first-pulse operation, the controller switching on the pump source to a pump power level S1 at least once during the first-pulse operation. A rise time E, after which the pump power level S1 of the pump source is attainable and starting from the time the pump source is switched on, is in a range of 50 ns to 350 ns.
