Abstract

The invention concerns a phacoemulsification probe having an acoustic transducer (3) which vibrates a needle (94), and further comprising a reflector (43) for reflecting energy toward the needle which would otherwise not be transmitted to the needle, and means (46, 66) for maintaining a constant pressure between the transducer (3) and the electrodes (50) which supply power to it.
