Abstract:
An eye injector for transferring a substance across the surface of the eye of an animal includes a needle-free injector and a patient positioning mechanism. The needle-free injector includes a reservoir for storing the substance to be transferred, a nozzle in fluid communication with the reservoir; and a controllable electromagnetic actuator in communication with the reservoir. The eye injector can also include a targeting light source for directing a beam of light into a pupil of the eye. The needle-free injector can be positioned adjacent to the lens of the eye, therefore producing a jet that intersects with the beam of light at a point in the retina.
