Abstract: Certain aspects of the present disclosure generally relate to ophthalmic surgery, and more particularly, to methods and apparatuses for controlling intraocular pressure (IOP). An exemplary apparatus generally includes a proximal segment comprising a first inner diameter (ID), an intermediate segment coupled to the proximal segment, the intermediate segment comprising a second ID smaller than the first ID, and a distal segment coupled to the intermediate segment, the distal segment comprising a third ID smaller than the second ID.

Abstract: A trocar-cannula insertion tool for ophthalmic procedures may include a cap with a body having a proximal end and a distal end opposite the proximal end. A marking element extends in a distal direction from the distal end of the body and includes at least one marking tip for forming one or more indentations on a patient's eye during an ophthalmic procedure. A manipulation element extends from the body in a direction different from the marking element and includes at least one manipulation tip for gripping a tissue of the patient's eye during the ophthalmic procedure. The cap may further include at least one window for exposing a photoluminescent cannula of the trocar-cannula insertion tool to light, enabling the cannula to absorb photons prior to insertion thereof.

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: Certain embodiments herein disclose a cannula assembly. The cannula assembly comprises a cannula, having a proximal end and a distal end. The cannula comprises a head at the proximal end, the head having one or more wings. The cannula also comprises a hollow rod extending from the head to the distal end. The cannula assembly also comprises a hub couplable to the head and having a housing with an inner wall. The inner wall comprises an undercut, and one or more distal ends of the corresponding one or more wings are configured to fit into the undercut and couple the hub to the head upon insertion of the head into the hub.

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.
