Abstract
The present invention is an intraocular surgery system using a Venturi pump and capable of preventing clogging due to nucleus fragments, despite a reduced aspiration flow rate. The intraocular surgery system includes: an air pumping means (); a Venturi tube () to which air is supplied from the air pumping means; a drainage tank () that is connected to a narrowed part of the Venturi tube; an intraocular surgery device () configured to fragment a nucleus inside an eye using ultrasonic vibrations, and discharge the nucleus together with a perfusate; a first aspiration tube () through which the perfusate discharged from the intraocular surgery device passes; a separation device () to which the first aspiration tube is connected, and that is configured to separate the nucleus from the perfusate that has flown from the first aspiration tube; and a second aspiration tube () that has an inner diameter that is smaller than an inner diameter of the first aspiration tube, and is configured to supply the drainage tank with the perfusate discharged from the separation device.
