An aspiration tube that has a relatively high fluidic resistance. The tube is coupled to a medical device and a pump of an aspiration system. The tube can be designed to create a pressure drop that at least equals the maximum vacuum pressure of the pump. The fluidic resistance can be accomplished with a tube having an inner diameter less than 0.06 inches. The aspiration tube and an irrigation tube may be coupled to an anterior chamber of a cornea during a phaco procedure. The high resistance of the aspiration tube minimizes the instantaneous change of flowrate out of the cornea in the event an occlusion is cleared from the tube. The aspiration tube is sized so that even if a maximum pressure occurs, the resultant aspiration flowrate will be such that the cornea will not be damaged when an occlusion is cleared from the tube. An in-line filter may also be attached to the aspiration tube to filter out particles in the system.
