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.

Eye model with bubble management

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.
