A method and system for controlling the cutting speed of a cutting device employable in an ocular surgical procedure is provided. The computer includes a user application and a multi-target controller. The first gate controller includes a first gate transformer, and a leakage inductance of the first gate transformer forms a resonant circuit with an input capacitance of the first power transistor. Thus, the phase errors of the subcarriers can be corrected and the OFDM symbols can be demodulated even if a frequency error and a timing error are occurring between the transmitter and receiver. Tissue can be dilated about the clamping device and an anastomotic device provided to the vessel.
