Abstract

The invention is generally directed to phacoemulsification systems and methods, and more particularly to systems and methods for providing transverse phacoemulsification. In accordance with one embodiment, a phacoemulsification system is provided having a handpiece with a needle, wherein the phacoemulsification system is configured to vibrate the distal end of the needle in both an effective transverse direction and an effective longitudinal direction when power, having a single effective operating frequency is applied to the handpiece.

Claims

1. A phacoemulsification system comprising:

a phacemulsification handpiece having a needle, having a distal end, for phacoemulsification, wherein the phacoemulsification handpiece is configured to vibrate the distal end of the needle in both an effective transverse direction and an effective longitudinal direction when power, having a single effective operating frequency is applied to the handpiece; and

a control unit operatively coupled to said phacoemulsfication handpiece to provide the power.

2. The phacoemulsification system of claim 1, wherein the control unit is configured to enable the phacoemulsification handpiece to vibrate the needle in an effective transverse direction, an effective longitudinal, and a hybrid of both effective longitudinal and effective transverse direction.

3. A phacoemulsification system comprising:

a phacemulsification handpiece having a needle, having a distal end, for phacoemulsification, wherein the phacoemulsification handpiece is configured to vibrate the distal end of the needle in both an effective transverse direction and an effective longitudinal direction when a single pulse of power is applied to the handpiece; and

a control unit operatively coupled to said phacoemulsfication handpiece to provide the pulse of power.
