Abstract
An ophthalmic aspiration system that can be used with a hand piece and a vacuum source, is disclosed and claimed. The aspiration system includes a first tube that is connected to the hand piece and a second tube that is connected to a vacuum source. A filter assembly is connected to both tubes to filter out particles aspirated into the system. The second tube has an inner diameter smaller than an inner diameter of the first tube. The smaller second tube limits the amount of flow through the system to minimize vacuum surges caused by occlusions.
