A lacrimal drainage manometer includes a syringe, a pressure sensor operably coupled to the syringe, a flow sensor operably coupled to the syringe, and a user feedback unit. The syringe includes a syringe body and a piston. The syringe body defines a fluid cavity in fluid communication with a cannula, which is configured for insertion into at least a portion of a lacrimal drainage system. The piston is for dispensing a fluid from the fluid cavity through the cannula. The user feedback unit is in electrical communication with each of the pressure sensor and the flow sensor. The user feedback unit is operably coupled to the syringe and configured to provide user feedback based on data from the pressure sensor and/or the flow sensor.
