A surgical device such as a therapy device that can allow a surgeon to treat a target tissue with ultra-violet (UV) light ablation therapy. In one example, the therapy device is configured to treat menorrhagia. In that instance, the therapy device may be configured to effect or destroy the endometrium during a procedure treating menorrhagia.

A method for noninvasive treatment of diabetic retinopathy helps prevent and reverses diabetic retinopathy and other vascular retinopathies, such as diabetic macular edema for a patient. The method comprises administering at least 80 percent pure oxygen to a patient in an oxygen chamber or nasal cannula. The oxygen chamber includes light emitting diodes that emit a light having a wavelength between 630-700 nm wavelengths on the patient. The method also includes administering an anti-inflammatory agent; an anti-oxidant; at least one of the following: an amino acid, arginine, and citrulline; and an omega-3 fatty acids to the patient. In extreme cases of diabetic retinopathy, a cold laser therapy is also administered to the patient with a wavelength between 570 nanometers and 1000 nanometers. The combination of all the aforementioned treatment modalities and compositions that work to synergistically to achieve unexpected clinical results for prevention and reversal of diabetic retinopathy.

White light luminaire for everyday activities that regenerates the retina of the eye in real time, damaged by blue light, contains at least one blue chip covered by a luminophore with the maximum of the radiated energy at the wavelength =670 to 680 nm, whereas the ratio between the blue spectral component from the wavelength range 400 to 490 nm and the green spectral component from the wavelength range 490 to 570 nm is 1:1.6 max., or the ratio between the green spectral component from the wavelength range 490 to 570 nm and the red spectral component from the wavelength range 570 to 780 nm is 1:3 min.

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.

One embodiment is directed to a system for altering the function of a sensory unit that innervates a targeted tissue region in an animal, the sensory unit being configured to express a light-responsive protein, comprising a light delivery element configured to direct radiation to at least a portion of a targeted tissue structure; and a light source configured to provide light to the light delivery element; wherein the targeted tissue structure is illuminated transcutaneously with radiation such that a membrane potential of cells comprising the targeted tissue structure is modulated at least in part due to exposure of the light-responsive protein to the radiation.

Disclosed is an example of a system for selectively influencing the circadian system of a human being, or other human stimulus factor, while simultaneously making minimal shifts to a specified operational parameter of the light source, such as correlated color temperature (CCT), color rendering index, look on a fixture, net lumen output, or a power consumption requirement. An example involves image processing to produce drive signals for emitters of a source array in a luminaire and an associated illumination control function to continuously meet a specific melanopic lux or circadian stimulus value, while adjusting/optimizing one or more other operational parameters of the source emitter outputs to achieve or maintain the operational parameter, such as light output level or power consumption, to within some acceptable degree of tolerance.
