Dermatological systems and methods for providing a therapeutic laser treatment using a handpiece delivering one or more therapeutic laser pulses to a target skin area along a first optical path, and sensing the temperature of the target skin area based on infrared energy radiating from the target skin area along a second optical path generally counterdirectional to the first office action, and sharing a common optical axis with the first optical path for at least a portion of the first and second optical paths. The handpiece may also provide contact cooling for a first skin area comprising the target skin area.

The present application is directed to a method for the regulation of the development of ocular refractive errors, comprising: controlling at least one light source using a processor, the at least one light source emitting an electromagnetic radiation variable with respect to one or more of a direction, an illuminance, a retinal area, an amplitude, a wavelength, and a spectral output; and regulating the at least one light source and producing a spectral power distribution at a plane of an eye.

A light therapy system (12) for administering a controllable melanopic luminous exposure includes a controllable lighting assembly (16) for use in delivering the desired luminous exposure. The system further includes a visual display means (18) for presenting at the same time a visual output such as a video to the patient. A target melanopic luminous exposure for administration to the patient is received by a controller 24. This target is then adjusted to compensate for an additional melanopic luminous exposure which the visual display means generates in displaying the visual output. A control schedule is then generated for controlling an illuminance of the lighting assembly to deliver over a defined treatment period the adjusted target melanopic luminous exposure. The lighting assembly is then controlled according to the control schedule. In this way both the visual output of the visual display means and the light output of the lighting assembly can be administered, while ensuring that the original target melanopic luminous exposure is delivered and not exceeded.

The present invention relates to a device to photocure and/or photoactivate a photosensitive material. The device comprises several subsystems to transmit light towards an area of interest where a photosensitive material is applied as well as to collect light reflected by the applied photosensitive material. Reflected light is analyzed by an optical detector to monitor the photocuring and/or photoactivation process. Further means to inject or otherwise apply a photosensitive material can be combined in the same device. Methods for applying a fluent polymerizable material to a target site and for effecting polymerization of the fluent light-sensitive material in situ are also disclosed.

Phototherapy systems comprising a therapeutic lamp platform for radiant lamps such as LEDs disposed in a holdable spot applicator assembly, the holdable spot applicator assembly including a reflective surface facing towards a patient and a plurality of LEDs for communicating lamp radiation from the lamps to a user. The lamps and associated circuitry are housed within a holdable elongated structure.

The invention provides a light therapy device for providing therapeutic treatment to a user's body, wherein the user may be a person or an animal. The device is using a light projection method for treating the body problems and/or skin disorders. Further, the device is having a rotatable assembly that automatically follows the movement of the desired area of the body needs to be treated. The device uses artificial intelligence, machine learning, localization modules, object detection module, image processing module, and 3D-mapping to automatically identify and treating the desired area of the body. Furthermore, the user can manually identify, select and prioritize desired treatment portion and can select the type of treatment required.

The invention provides a system and related equipment for the precise measurement of the output characteristic of a light source, e.g., a dental light curing unit (LCU) or light for photodynamic therapy, using a light collector, a light detector, and a computer programmed to deliver the value of the output characteristic of the light source to the user. The systems allow for the determination of a proper 5 exposure time or the selection of a light source as needed for a specific application. The invention also provides a light device.

An optical output device for skin care, according to an embodiment of the present disclosure, comprises: a substrate disposed such that at least one light source is oriented toward a user's skin; a front cover covering one surface of the substrate; a rear cover covering the other surface of the substrate; a wearing device coupled to the rear cover so as to make contact with a part of the user's body such that the optical output device for skin care is worn by the user; and a wearing detection sensor for detecting whether the user is wearing the device.

A treatment method and a treatment system capable of effectively irradiating an antibody-photosensitive substance bound to a tumor cell with a near-infrared ray. The treatment method includes: intravenously administering the antibody-photosensitive substance; inserting a guide wire and a catheter into a main artery of an organ having the tumor cell; removing the guide wire; inserting an optical fiber into the catheter and advancing the optical fiber to a target position while checking a position of the optical fiber with an orientation marker disposed on the optical fiber; and irradiating the antibody-photosensitive substance bound to a tumor cell membrane with the near-infrared ray from the optical fiber while reducing an influence of blood in the artery on the near-infrared ray after 12 hours to 36 hours from intravenous administration.

An apparatus to treat refractive error of the eye comprises one or more optics configured to project stimuli comprising out of focus images onto the peripheral retina outside the macula. While the stimuli can be configured in many ways, in some embodiments the stimuli are arranged to decrease interference with central vison such as macular vision. The stimuli can be out of focus images may comprise an amount of defocus within a range from about 3 Diopters (“D”) to about 6 D. In some embodiments, the brightness of the stimuli is greater than a brightness of background illumination by an appropriate amount such as at least 3 times the background brightness. In some embodiments, each of a plurality of stimuli comprises a spatial frequency distribution with an amplitude profile having spatial frequencies within a range from about range of 1×10.sup.−1 to 2.5×10.sup.1 cycles per degree.
