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.

Abstract: Systems, apparatuses, and methods of and for an ophthalmic illumination system are disclosed. In an exemplary implementation, an ophthalmic illumination system includes a collimator having at least one lens. The system includes a first mirror arranged to reflect light towards the collimator. The first mirror is configured for use with a first light source that emits a first light beam having a first parameter. The system includes a second mirror arranged to reflect light towards the collimator. The second mirror is configured for use with a second light source emitting a second light beam having a second parameter that is different than the first parameter. The second mirror is shaped and arranged to cause a reflected portion of the second light beam to have the first parameter. The first mirror and the first light source, and the second mirror and the second light source, are separately usable with the collimator.

Abstract: An illuminated microsurgical surgical instrument that allows for illumination of the interior of a body cavity during a surgical procedure is provided herein. The surgical instrument may include an elongate tubular member having a distal end for insertion through tissue, the elongate tubular member having an inner diameter, an outer diameter, and a wall thickness. A longitudinal slot extending from the distal end of the elongate tubular member is formed in the elongate tubular member. The surgical instrument further may include an optical fiber extending within the longitudinal slot toward the distal end of the elongate tubular member. The optical fiber may be affixed within the longitudinal slot by an adhesive. The optical fiber may be positioned such that a distal tip thereof is protected from damage by a distal edge of the elongate tubular member during insertion of the instrument into the body cavity.

Abstract: An illuminated surgical instrument has a working area located near an end of the instrument. An array of optical fibers terminates near the end of the instrument. The array of optical fibers is located adjacent to the instrument such that the array of optical fibers provides targeted illumination to the working area only on one side of the instrument.

Abstract: An ophthalmic endo-illumination system includes a light source that produces a light beam, a fiber port that receives an optical fiber, a condenser that couples at least a portion of the light beam into the optical fiber received at the fiber port, and a beam splitter disposed between the fiber port and the condenser. The beam splitter is configured to receive the light beam from the condenser and split the light beam into a first beam which is coupled to the optical fiber and a second beam which is coupled to a monitoring fiber. An optical sensor is provided to detect an amount of the second beam output from the monitoring fiber. The coupling efficiency of the first beam coupled into the optical fiber may be determined based on the amount of the second beam output from the monitoring fiber.
