The web and literature report various mechanisms that are said to occur\, and some myths\, which have been discussed for decades. This talk will report various ultrasonic measurements and the results of an investigation of the interaction of ult rasonic tools with materials and the mechanisms that can be seen to occur. The results show that phacoemulsification is most likely dominated by the direct action of the vibrating tip of the tool used against tissue. The s ource of the “cavitational hiss\,” that has been reported\, is clearly identified. The insights given will\, hopefully\, reduce some of the myst ery and mythology that still surrounds the physics of the fundamental inte ractions\, for what is generally a safe and effective procedure for catara ct removal.\n\nSpeaker(s): Leonard Bond\n\nAgenda: \nVirtual Meeting\n---- -----------------------------------------------------------\n\nNo IEEE mem bership is required.\n\nVirtual: https://events.vtools.ieee.org/m/448523 LOCATION:Virtual: https://events.vtools.ieee.org/m/448523 ORGANIZER:muthu.elen@pnnl.gov SEQUENCE:30 SUMMARY:IEEE Sensor's Talk by Prof. Leonard J.
