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: Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure. The infusion cannula includes a tubular body with a tubular inlet located at a proximal end of the tubular body and a tubular outlet located at a distal end of the tubular body. The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.

Abstract: Certain aspects of the present disclosure generally relate to ophthalmic surgery, and more particularly, to methods and apparatuses for controlling intraocular pressure (IOP) and administering ocular tamponades during or after ophthalmic surgery. An exemplary apparatus generally includes a proximal segment having a first inner diameter (ID), a first proximal end, and a first distal end. The apparatus further includes a distal segment having a second ID smaller than the first ID, a second proximal end, and a second distal end configured to be disposed inside a hub or a cannula transition of a valved cannula comprising the hub, a shaft, and the cannula transition between the hub and the shaft.

Abstract: A platform configured to secure a service loop of tubing from a fixed position surgical device. The platform allows for avoidance of taping and re-taping of service loops. Additionally, the platform provides stability to the surgical device so as to avoid unintentional changing of position or orientation of the device. This is of particular benefit for an infusion port during eye surgery and other similar devices where orientation of the installed device aids device performance.
