An ophthalmic device for illuminating an interior region of a patient's eye includes a polymeric, at least partially transparent body having a first surface contoured to substantially conform to an ocular surface and a second surface opposed to the first surface; a light source; and an optical element for directing light through the first surface such that, with the first surface in contact with a corneal surface of the patient's eye, a portion of interior region of the patient's eye illuminated by the light source is visible through the first and second surfaces. In certain embodiments, the light source is sufficient to illuminate the retina so that an ophthalmic surgeon may view the eye during an evaluation or surgical procedure without the need for invasive probes, cameras, or other equipment.

The invention relates to glasses provided with two transparent spectacle glasses enclosed in a frame. Each spectacle glass is positioned in front of a person's eye with the aid of a frame to be positioned on the ears and nose of said person. The glasses are further provided with at least one light source integrated in the frame for directly and/or indirectly delivering light to the eyes substantially from above. A nose frame part of the frame reflects at, at least, a nose frame side portion facing the eye, to the eye at least partially the direct or indirect incident light thereon originating from the light source.

A light irradiation medical device comprising: a shaft having a lumen extending in the longitudinal direction; and a light guiding device that is disposed in the lumen of the shaft and is movable in the longitudinal direction. The light guiding device extends in the longitudinal direction and has a light diffusion part at a distal part of the light guiding device. The shaft has: a first window in a peripheral wall of a distal part of the shaft; and a second window at a distal end face of the shaft. The shaft has a reflection surface inside the shaft and at a distal side with respect to the first window, and reflects light emitted from the light guiding device.

Embodiments of the invention include a compact, lightweight, hand-held laser treatment device that combines the emissions of two separate laser energy sources into a common optical pathway for improved therapeutic effect. In some embodiments, the device includes a housing having separate first and second laser sources disposed within the interior thereof. In some embodiments, the laser energy emissions from the two internal laser sources can be individually or concurrently transmitted to a delivery tip of the device via a laser transmission path also defined within the interior of the housing. In some embodiments, the structural and functional features of the first and second laser sources, in concert with the unique architecture of the laser transmission path, can be configured to provide efficacy and efficiency in the operation of the device within the spatial constraints of the lightweight, hand-held housing thereof.

Systems and methods for restructure and stabilization of bones that provide an anti-microbial effect are disclosed herein. A device includes a delivery catheter having an inner void for passing at least one light sensitive liquid, and an inner lumen; an expandable member releasably engaging the distal end of the delivery catheter; at least one channel positioned in the expandable member; and a light conducting fiber sized to pass through the inner lumen of the delivery catheter and into the expandable member, wherein, when the light conducting fiber is in the at least one channel, the light conducting fiber is able to disperse light energy to provide an anti-microbial effect. When the light conducting fiber is in the expandable member, the light conducting fiber is able to disperse the light energy to initiate hardening of the light sensitive liquid within the expandable member to form a photodynamic implant.

The present disclosure is directed to a phototherapeutic apparatus for focused UVB radiation and vitamin D synthesis and associated systems methods. In one embodiment a phototherapeutic apparatus can include a housing at least partially defining an irradiation zone, and an ultraviolet (UV) radiation source carried by the housing. The irradiation zone can be configured to accommodate at least a portion of a human patient. The phototherapeutic apparatus can further include a filter between the UV radiation source and the irradiation zone. The filter can be configured to at least substantially remove UV radiation outside of a predetermined spectrum centered at about 297 nm and having a bandwidth of at most 10 nm.

The present invention relates to a device for an application of directed actinic radiation to a subject, said device comprising: an exposition tunnel being capable of surrounding said subject to be exposed to said actinic radiation and being formed of one semi-cylinder barrel-shape first surface made of a material substantially permeable to said actinic radiation, and of at least one second surface made of said material substantially permeable to said actinic radiation and capable of complementing the first surface in forming said exposition tunnel; the surfaces of said exposition tunnel separating an inner space where said subject is exposed to said actinic radiation, from outer spaces where a plurality of radiation sources capable of emitting actinic radiation through said surfaces are mounted; said first and second parts of the chassis of the device being configured to complement each other in forming the outer shape of the device; said device further comprising at least one further outer space separated from said inner space and located at either one or both of the longitudinal ends of the exposition tunnel, said at least one further outer space housing a plurality of additional radiation sources configured to emit radiation, wherein at least one of the radiation sources and the additional radiation sources comprise at least one reflector or a plurality of reflectors. An improved device distinguishes in that at least one of the radiation sources and the additional radiation sources comprise LEDs or a plurality of LEDs, and that the at least one reflector or the plurality of reflectors collimate the radiation emitted by said at least one of the radiation sources and the additional radiation sources.

Device for printing three-dimensional objects using an energy-field projection system. In operation, energy is projected into a print medium according to a four dimensional (4D) energy-field function for exposing the print-medium to a threshold energy-intensity level that causes the print medium to harden in the shape of a three-dimensional object.

A contact lens configured to decrease dark adaptation comprises one or more LEDs and directs light from the LED away from the fovea and toward the parafovea or perifoveal regions of the retain. In some embodiments, soft contact lens embedded with one or more arrays of microLEDs and electronics operating the LEDs is configured to be worn at night in order to inhibit dark adaptation and reduce oxygen consumption by the rods. The contact lens may be made of a single layer of a contact lens material or multiple layers sandwiching a flexible transparent plastic layer comprising the electronics and the LED arrays. The contact lens may be made of a hydrophilic hydrogel material that is biocompatible to the human cornea, or a silicone hydrogel material. The contact lens may be spherical and may provide refractive correction to the eye of the wearer.

Disclosed is a device that utilizes a light-field display to project a virtual continuum of real world perspectives of a natural scene to a plurality of observer viewpoints to simulate a natural environment. An observer perceives different perspectives as he or she moves through the simulated environment just like the observer would as if he or she were in a natural environment.
