Abstract
An intraocular device for implantation in an eye of a patient is provided. The intraocular device includes an inlet tube, an outlet tube, and a microfluidic chamber. The microfluidic chamber includes a chamber inlet coupled to the inlet tube, a chamber outlet coupled to the outlet tube, and one or more fluidic barriers. Each fluidic barrier is configured such that, as a fluid is injected into the microfluidic chamber, a front of the fluid coincides with the fluidic barrier before any of the fluid passes beyond the fluidic barrier. Associated methods are also disclosed herein.

An intraocular device for implantation in an eye of a patient, comprising:
- an inlet tube;
- an outlet tube;
- a microfluidic chamber comprising:
- a chamber inlet coupled to the inlet tube;
- a chamber outlet coupled to the outlet tube;
- and
- three fluidic barriers configured such that a front of a fluid injected into the microfluidic chamber coincides with each fluidic barrier before the fluid passes beyond the fluidic barrier;
