The invention relates to a phacoemulsification system having: an irrigation fluid container for receiving irrigation fluid, an irrigation line through which the irrigation fluid can flow, a flow pump through which the irrigation fluid can flow, an aspiration line through which aspiration fluid can flow, an aspiration pump for suctioning aspiration fluid, a device for detecting a pressure signal on the basis of a pressure in the aspiration line, or a device for detecting a volume flow signal on the basis of a volume flow in the aspiration line, and a control device which is configured to receive the pressure signal or the volume flow signal, and to control the flow pump on the basis of the pressure signal or of the volume flow signal, in such a way that a change in the pressure or the volume flow takes place in the irrigation line, wherein the control device is configured for setting the speed of the flow pump at a frequency in the region of 0 to 10 Hertz, wherein the flow pump builds up a dynamic overpressure of up to 0.5 bar. |
