An eyedropper (2) is provided for administering a predetermined volume of liquid onto the surface of an eye (57). The eyedropper (2) includes a body (104) having a nozzle (27) in fluid communication with the internal cavity (114) of the reservoir body (18). Projecting from an inner surface (110) of the reservoir body (18) are a first projecting portion (25a, 125a) having a first contact surface (26a, 126a) and a second projecting portion (25b, 125b) having a second contact surface (26b, 126b). The first contact surface (26a, 126a) and the second contact surface (26b, 126b) are disposed opposite from one another and are spaced apart from one another. In use, the first and second contact surfaces (26a, 26b, 126a, 126b) limit the displacement volume of the internal cavity (114) when the eyedropper (2) is squeezed thereby limiting the volume of liquid expelled from the nozzle (27).
