Abstract
A method and apparatus for delivering energy during a surgical procedure such as phacoemulsification is provided. The method and apparatus include applying energy during at least one pulsed energy on period, comprising applying energy during a series of short burst periods, the short burst periods interspersed by short rest periods. The method and apparatus further comprise delivering minimal energy during a long off period, the long off period comprising a relatively long period when minimal energy is applied, wherein one long off period follows each pulsed energy on period. The short burst periods and the short rest periods are relatively brief in duration as compared with the long off period.
