A directional control valve for use in cataract surgery typically includes a valve, body and a valve switch. The valve body includes ports for inflow and outflow of fluid, as well as a hollowed out portion in which a core portion of the valve switch sits. The core portion of the valve switch can be in the form of a circular disc having internal core ports which can be caused to reversibly rotate between a first position and a second position, thereby causing fluid flow to the inflow/outflow ports to be alternately opened and closed, depending on which position the valve switch is turned.
