A Technical Talk will be given on the Title "The Physics of Cataract Surgery" by Prof. Leonard Bond. 

Abstract: 

Despite its unparalleled success and the common the use of phacoemulsification in the field of ophthalmic surgery, the precise mechanism of ultrasonic phacoemulsification for cataract extraction remains controversial. 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 ultrasonic 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 source of the “cavitational hiss,” that has been reported, is clearly identified. The insights given will, hopefully, reduce some of the mystery and mythology that still surrounds the physics of the fundamental interactions, for what is generally a safe and effective procedure for cataract removal.
