Abstract
In various embodiments, a phacoemulsification tip may include a shaft and a cutting edge portion having at least a first and second bend. The geometry of the tip may be configured to result in a lateral displacement (u), perpendicular to the shaft during torsional vibration of the tip at frequencies between 10 kHz and 60 kHz, of less than approximately 5% to 25% (e.g., 15%) of the lateral displacement at the distal end point of the tip throughout a portion of the shaft extending from the end of a conical portion of the tip through to the first bend in the cutting edge portion of the tip. Software and/or physical modeling may be used to determine the tip geometry.
