SYSTEM AND METHOD FOR CONTROLLING A TRANSVERSE PHACOEMULSIFICATION SYSTEM USING SENSED DATA
First Claim
1. A method for controlling an ultrasonically driven handpiece employable in an ocular surgical procedure, comprising:
- operating the ultrasonically driven handpiece in a first tip displacement mode according to a first set of operational parameters; and
altering operation of the ultrasonically driven handpiece to employ a second tip displacement mode using a second set of operational parameters;
wherein said altering comprises measuring an ocular surgical related parameter and dynamically selecting operational parameters based on the ocular surgical related parameter, wherein dynamically selecting comprises changing the first set of operational parameters for the first tip displacement mode relative to the second set of operational parameters for the second tip displacement mode.

Abstract
A method and system for use in an ocular surgical procedure is provided. The design includes a handpiece having an ultrasonically vibrating tip operational within a plurality of operating modes including a first operating mode and a sensing device, such as a vacuum pressure sensor. A controller is connected to the handpiece and sensing device and is configured to receive data from the sensing device and adjust at least one operational parameter (time/duty cycle of operation, power during operation) associated with the first operating mode and adjust at least one parameter associated with another operating mode based on the data received from the sensing device. Operational modes may include multiple longitudinal or non-longitudinal modes (torsional, transversal, etc.) or combinations of longitudinal and/or non-longitudinal modes.
