A surgical cassette arrangement is provided. The arrangement includes a flow selector valve configured to operate with a handpiece to selectively irrigate and aspirate fluid with respect to an ocular region. The flow selector valve includes at least three ports, with one port fluidly connectable to the handpiece. The arrangement further includes a reservoir fluidly connected to a second port of the flow selector valve via a first flow segment and configured to receive fluid from the flow selector valve, and a collector fluidly connected to a third port of the flow selector valve via a second flow segment and configured to receive fluid from the flow selector valve and from the reservoir. The flow selector valve selectively controls irrigation and aspiration flow to the handpiece and ocular region.
