Abstract
This invention provides for a method and an EMDU used to dispense precise quantities of liquids with an image sensor being capable of providing feedback to the user as to both, when an eye is properly aligned with the EMDU, and to detect and track the quantity of the dose administered on to the eye.
Claims13
An apparatus for dispensing liquid into an ophthalmic environment, the apparatus comprising:
- an automated dispenser for dispensing a liquid towards an eye based upon receipt of a logic signal;
- at least one blink detector configured to detect a blink of an eyelid of the eye;
- and
- a processor in logical communication with at least one of the blink detector and the automated dispenser, wherein the processor is configured to receive a signal indicating a first blink of the eyelid and, upon receipt of the signal indicating the blink, to trigger dispensation of the liquid;
- wherein the dispensation is programmed to occur in a period calculated to transpire before a second blink of the eyelid is physiologically possible.
