A fluid operated and controlled irrigation and aspiration device for ophthalmic use. A source of fluid under pressure is connected through foot pedal operated valves to clamps for controlling irrigation through a conventional handpiece, and to a vacuum generating device. Selecting valves are provided for isolating the vacuum generating means, and for directing pressure to a pulsing circuit. The pulsing circuit can be used to control the vacuum to yield a pulsing aspiration; and, in a modification of the device, the pulsing circuit can be used to control a pressure circuit to operate a cutting device.
