Devices and methods for intraocular fluid injection are disclosed. A device can include a surgical instrument for an ophthalmic procedure. The surgical instrument can include a handle. A fluid compartment can be coupled to the handle and configured to hold a substance. A tool can be coupled to the distal end of the handle and have a lumen configured to convey the substance into an intraocular site of a patient. A piston can be in the handle and configured to reciprocate along the longitudinal axis of the handle to draw the substance from the fluid compartment and eject the substance through the lumen of the tool. A push button can be on the lateral side of the housing and configured to engage the piston via a sloped surface to actuate a forward stroke of the piston towards the distal end of the handle.

Device for intraocular injection

A simulated eye surgical model with a bubble management system that facilitates training of ophthalmic surgical procedures, such as laser-based glaucoma treatment. The simulated eye could also be used for marketing, startup procedures, go/no-go tests, etc. The eye model has a lower core, a corneal dome positioned above the lower core, and an anterior chamber under the corneal dome defining a floor. A bubble reservoir under the anterior chamber defined by the lower core has a capture tube opening to the anterior chamber. A bubble chamber open to the capture tube rises up above the capture tube lower end to an upper portion sealed off from the anterior chamber. The eye model may be rotated 360° about a horizontal axis to transfer bubbles from the anterior chamber to the bubble chamber. An alternative flow-through eye model provides active flushing of bubbles and particulate.

Device and method for intraocular fluid injection

A simulated eye surgical training tool, namely an eye model that facilitates training of ophthalmic surgical procedures, such as goniotomy and trabecular meshwork manipulation. The eye model includes a core made of a rigid material and a Canal frame disposed at an upper end of the core that defines an inwardly-facing Schlemm's canal groove in an inner wall thereof. Various structures may be used in or across the Schlemm's canal groove to simulate a trabecular meshwork. For instance, a flexible sheet may span across the groove, or a soft material placed in the groove. Color or opacity may be used to distinguish the groove from surrounding structures. Also, a corneal dome having an upper hemispherical portion is mounted over the Canal frame, and a scleral dome having an upper bore is mounted around the corneal dome. The core may be mounted on one of a number of angled pedestals on a base.

Intraocular drainage devices, intraocular implantation procedures, and inserter devices for intraocular implantation procedures are disclosure. A disclosed intraocular drainage device includes a tube having a distal end and a body disposed proximal to the tube. An inlet port is disposed on the distal end of the tube and configured to receive an influent fluid from an anterior chamber of an eye. An inlet fluid pathway is coupled to the inlet port and extends at least partially through the tube. A plurality of outlet fluid pathways extend at least partially through the body and branch from the inlet fluid pathway. A plurality of outlet ports are disposed on the body and coupled to the plurality of outlet fluid pathways. A disclosed inserter device for an ocular implantation procedure includes a handle, a needle, and a plunger. The needle is disposed on a distal end of the handle and configured to hold an intraocular drainage device. The plunger is coupled to the needle and disposed in the handle. The plunger is disposed distal to a vacuum chamber within the handle and configured to retract the needle based on a proximal force applied by the vacuum chamber.
