Abstract
A phacoemulsification simulation apparatus includes a trigger device, at least two sensors, and a processor. The trigger device configured to apply, to fluid at an inlet of a needle of a phacoemulsifier, a pressure profile as a function of time in response to an input waveform. The at least two sensors are configured to measure a pressure of the fluid at respective points in the phacoemulsification simulation apparatus. The processor is configured to (a) drive the trigger device with the input waveform, thereby causing the trigger device to apply the pressure profile to the inlet while the fluid is aspirated via an aspiration line, (b) receive measurements of the pressure of the fluid from the at least two sensors, and (c) analyze an aspiration performance of the phacoemulsifier in response to the measurements.
