An ophthalmic injection device has a dispensing chamber, a storage chamber, a piezoelectric array, a needle fluidly coupled to the dispensing chamber, a power source for providing power to the piezoelectric array, and a controller for controlling the power source. A dispensing chamber housing has an inner surface and an outer surface. The inner surface defines a dispensing chamber for receiving a quantity of a substance. The storage chamber is located near the dispensing chamber housing. The piezoelectric array is located between the storage chamber and the dispensing chamber housing. A housing at least partially encloses the dispensing chamber housing, the storage chamber, the piezoelectric array, the power source, and the controller. The piezoelectric array is activated to pump the substance from the storage chamber to the dispensing chamber.
