Embodiments disclosed herein provide devices, systems, and methods for instrument exchanges during ophthalmic surgery. More particularly, the present disclosure relates to valved cannula assemblies and methods of use thereof. A valved cannula assembly includes a cannula having a head at a proximal end of the cannula and a hollow rod extending from the head to a distal end of the cannula. The valved cannula assembly includes a valved hub coupled to the head and including a septum having two or more curved flaps configured to provide an opening for an instrument.

Cannula protector with scleral markers

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.
