Abstract
An ophthalmic surgical systemdetects a change in a viscosity of a material being aspirated from an eye. The systemincludes a control moduleconnected to an aspiration pump, and a flow meterconnected to the control moduleand the aspiration pump. The flow meterprovides a flow rate of material aspirated from the eyeby the aspiration pump. A surgical handpiececonnected to the aspiration pumpand the control moduleis inserted into the eyeduring surgery. The control module, during surgery, detects a step change in the flow rate of material aspirated from the eyeand the control modulefurther causes the surgical systemto alert a surgeon that a change in viscosity of the material being aspirated has been detected indicating that the handpiecehas moved from a material of a first viscosity to a material of a second viscosity.
