Abstract: In some embodiments, a vitrectomy probe may include an inner cutting tube reciprocating in an outer tube. The outer tube includes a side port and the inner tube includes a distal cutting port, and, in some embodiments, an additional side port. In some embodiments, the inner tube may also include a flat upper edge that cuts across the outer tube side port. In some embodiments, a diaphragm drives the inner tube and may have an open-stroke side with a lower hardness material than a closed-stroke side. In some embodiments, an aspiration tube coupled to the vitrectomy probe may include a first aspiration tubing and a second aspiration tubing with a lower hardness than the first aspiration tubing. In some embodiments, the vitrectomy probe may be coupled to pneumatic tubing that is stepped or tapered.

Abstract: Embodiments disclosed herein provide devices, systems, and methods for illuminating inside an eye globe. More particularly, the present disclosure relates to ergonomic chandelier illumination systems for illumination of a surgical site during ophthalmic surgery, the chandelier illumination systems having improved flexibility, profile, and light coupling efficiency. In certain embodiments, a malleable chandelier illumination probe, which is bendable by a surgeon to any desired angle, is disclosed. In certain other embodiments, a preformed chandelier illumination probe, which is preset to a desired angle using a heating method, is disclosed. In certain other embodiments, a method for belling and binding two optical fibers to create a dual chandelier output with improved light coupling efficiency, which is capable of being used with a single connector, is disclosed.

Abstract: The present disclosure relates to a laser probe assembly coupled to a laser system through an optical fiber cable. In one example, the laser probe assembly comprises a probe tip coupled to the probe body, the probe tip housing multiple fibers. Each of the multiple fibers comprises a proximal end that couples to the laser system and a distal end that terminates in the probe tip, a single core for transporting a laser beam provided by the laser system, and a cladding surrounding the core. The laser probe assembly also comprises a lens for projecting multiple laser beams provided by the multiple fibers on to a surgical site. Within the probe tip, parts of outer surfaces of portions of any two adjacent fibers of the multiple fibers touch. Also, the multiple fibers are at least substantially centered with respect to the lens.
