1. A system, comprising:
a first actuator, which is configured to vibrate along a first axis in response to a first driving signal;
a second actuator, which is configured to vibrate along a second axis, different from the first axis, in response to a second driving signal;
a third actuator, which is configured to vibrate along a third axis, different from the first axis and the second axis, in response to a third driving signal;
wherein the first axis, the second axis and the third axis are orthogonal to one another;
a needle, which is configured to be vibrated by the first actuator, the second actuator and the third actuator, so as to emulsify a lens of an eye; and
a generator, which is configured to generate the first driving signal, the second driving signal and the third driving signal based on a vibration pattern specified for the needle.
