A drop metering device for use in combination with an eye dropper or other liquid dispenser comprises a rigid receptacle having an open chamber for removably receiving a squeeze bottle of the dropper. The plunger is mounted to reciprocate radially inwardly with respect to the rigid receptacle so that, when the squeeze bottle is in place, a controlled deflection can be induced in the squeeze bottle. The plunger may be mounted on a lever arm with a ring adjustment mechanism which provides a variable stop surface between the lever arm and the receptacle. Alternatively, the plunger may be mounted in a radially oriented slide bearing with a threadably mounted stop member for adjusting the length of travel.
