The present invention relates to an ophthalmic treatment apparatus and a control method therefor, the ophthalmic treatment apparatus comprising: a display unit for displaying an image of a patient's eyeground; a treatment region setting unit for setting a treatment region on the basis of the image of the patient's eyeground; a treatment light radiating unit for radiating treatment light to the set treatment region; a radiation density setting unit for setting radiation density of the treatment light radiated to the set treatment region; and a control unit for controlling the treatment light radiating unit so as to radiate the treatment light onto the set treatment region on the basis of the set density.

A laser-surgical apparatus includes a laser emitting laser light with a narrowband wavelength distribution, a digital image sensor or a plurality of digital image sensors that separately record(s) different color channels that represent mutually different spectral wavelength distributions with in each case one maximum corresponding to a specific spectral color and produce(s) separate pieces of image information for the individual color channels, and a graphics module for combining the separate pieces of image information into one color image. In addition, it includes a manipulation module for suppressing the laser light in the color image, which makes it possible to electronically manipulate the pieces of image information of the color channel the spectral wavelength distribution of which has the largest overlap with the narrowband wavelength distribution of the laser light before the separate pieces of image information are combined or during the combining of the separate pieces of image information.

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.

A method for treating, preventing and/or reducing neurodegeneration in subjects with neurodegenerative disease, such as those neurodegenerative diseases that affect the eye, including glaucoma, using radiation, such as gamma radiation or X-ray radiation, either alone or together with a bone marrow transfer treatment. The method includes irradiating a targeted area of an animal, such as the eye region, with radiation, either alone or followed by injection with T-cell depleted bone marrow cells. Also a method for screening and/or selecting agents and/or treatment methods for inhibiting, treating and/or reducing neurodegeneration, particularly the neurodegeneration of the eye that occurs as a consequence of glaucoma.

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.

An ophthalmic surgical system includes an imaging device configured to acquire a first image of a fundus of an eye and a hemorrhage detecting unit. The hemorrhage detecting unit includes a processor configured to receive the first fundus image from the imaging device, analyze the first fundus image to detect a hemorrhage in the eye, and in response to detecting the hemorrhage, send a signal to an intraocular pressure controller. The ophthalmic surgical system further includes the intraocular pressure controller, which includes a processor configured to receive the signal from the hemorrhage detecting unit, in response to the received signal, determine if a current intraoperative pressure of the eye is below a predetermined threshold, and in response to determining the current intraoperative pressure of the eye is below the predetermined threshold, generate a signal to increase the intraoperative pressure of the eye.

The present invention relates to an ophthalmic treatment device and a control method therefor, and provides an ophthalmic treatment device and a control method therefor, the ophthalmic treatment device comprising: a treatment beam irradiation unit for irradiating a therapeutic beam to a fundus oculi; a guide image unit for acquiring a guide image of an area including a position onto which the therapeutic beam is irradiated among the area of the fundus oculi; and a display unit for displaying a fundus oculi image of a patient and the position to which the therapeutic beam is irradiated on the fundus oculi image, using the guide image.

A single-use laser probe with reusable optic fiber fixtures may include a transitory connector having a transitory connector distal end and a transitory connector proximal end; a tube having a tube distal end and a tube proximal end; and an optic fiber having an optic fiber distal end and an optic fiber proximal end. The optic fiber may be disposed in the transitory connector wherein the optic fiber proximal end extends a distance from the transitory connector distal end. The optic fiber may be disposed in the tube wherein the optic fiber distal end is coplanar with the tube distal end. The transitory connector may be configured to interface with a reusable optic fiber fixture.

Some embodiments disclosed here provide for a method fragmenting a cataractous lens of a patient's eye using an ultra-short pulsed laser. The method can include determining, within a lens of a patient's eye, a high NA zone where a cone angle of a laser beam with a high numerical aperture is not shadowed by the iris, and a low NA zone radially closer to the iris where the cone angle of the laser beam with a low numerical aperture is not shadowed by the iris. Laser lens fragmentation is accomplished by delivering the laser beam with the high numerical aperture to the high NA zone, and the laser beam with the low numerical aperture to the low NA zone. This can result in a more effective fragmentation of a nucleus of the lens without exposing the retina to radiation above safety standards.

A process that provides protective therapy for biological tissues or fluids includes applying a pulsed energy source to a target tissue or a target fluid having a chronic progressive disease or a risk of having a chronic progressive disease to therapeutically or prophylactically treat the target tissue or target fluid. The pulsed energy source has energy parameters selected so as to raise the target tissue or bodily target fluid temperature up to a predetermined temperature for a short period of time to achieve a therapeutic or prophylactic effect, while the average temperature rise of the target tissue or target fluid over a longer period of time is maintained at or below a predetermined level so as not to permanently damage the target tissue or target fluid.
