    Abstract: An illuminated microsurgical instrument is provided herein that includes a microsurgical instrument having a tubular member arranged to treat patient tissue at a surgical site, the tubular member having a distal tip, an inner surface, and an outer surface. The inner surface defines a lumen. The outer surface has a notch formed therein. The illuminated microsurgical instrument further includes an optical fiber arranged to deliver light to the surgical site. The optical fiber includes a proximal end arranged to receive a light beam from a light source and also includes a curved distal end arranged to emit light adjacent to the distal tip. A portion of the curved distal end is positioned within the notch and curves away from the tubular member.

    Abstract: An ophthalmic illumination system includes a light source generating a source light beam and a beam splitter splitting the source light beam into first and second light beams. A first attenuator is located in a path of the first light beam and a second attenuator is located in the path of the second light beam, the first and second attenuators operable to change the intensities of the first and second light beams, respectively. A first optical fiber port is configured for connection to a first optical fiber for delivering the first light beam to a patient's eye and a second optical fiber port is configured for connection to a second optical fiber for delivering the second light beam to the patient's eye. A control unit is communicatively coupled to the first and second attenuators and is operable to adjust the attenuators to control the intensities of the light beams delivered to the patient's eye.

    Abstract: A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

    Abstract: An ophthalmic illumination system includes a broadband light source configured to emit a white laser beam, a first monochromatic light source configured to emit a first monochromatic laser beam having a first central wavelength, optics configured to receive a combined light beam comprising the white laser beam and the monochromatic laser, and a controller comprising a processor and a memory configured to control a chromaticity of the combined light beam by changing an output power of the first monochromatic light source.

    Abstract: An illumination fiber optics is provided that includes an optical fiber, configured to receive illumination light at a proximal end from a light source; and a light-scattering element, at a distal end of the optical fiber, configured to receive the illumination light from the optical fiber at a proximal end and to emit the illumination light at a distal end in a wide angle. The illumination fiber optics can be prepared by providing an optical fiber, configured to receive illumination light at a proximal end from a light source; and creating a light-scattering element at a distal end of the optical fiber, configured to receive the illumination light from the optical fiber at a proximal end and to emit the illumination light at a distal end in a wide angle.

    Abstract: Multi-fiber laser probes utilize relative motion of fibers and other laser probe elements to preserve small-gauge compatibility while providing for multi-spot beam deliver, or to provide for the selectively delivery of single-spot or multi-spot beam patterns. An example probe includes fibers having distal ends that are movable as a group onto a distal ramp element affixed to a distal end of a cannula, so that the distal ends of the fibers can be moved between a retracted position, in which the distal ends of the fibers are within the cannula or ramp element, and an extended position, in which distal ends of the fibers are guided by grooves or channels of the ramp so as to extend at least partially through external openings in the distal end of the laser probe and so as to be pointed angularly away from a longitudinal axis of the cannula.
