A peristaltic pump (10) for use in ophthalmic surgery includes a housing (12), a pump head (14) having plurality of rollers (16), a backing plate (18) attached to the housing (12), and a length of surgical tubing (50). The rollers (16) and backing plate (18) cooperate to pinch the length of surgical tubing (50) to peristaltically pump fluids from a surgical site to a collection bag (64). At least one of the pump head (14) and the backing plate (18) is moveable, during operation of the pump (10), from a tubing pinched position to a tubing vent position. This movement allows the tubing (50) to be vented by removing the pinched closure of the tubing (50).
