Abstract
Systems and methods for sensing tissue in a phacoemulsification procedure are provided herein. A method may include generating a sensing signal through a frequency range centered at a local resonant frequency of an ultrasonic handpiece and measuring impedance characteristics of the signal at a distal end of a needle of an ultrasonic handpiece. A method may further include comparing the measured impedance characteristics of the generated sensing signal with one or more stored impedance profiles.…
