The hypersonic vitrector is a novel ultrasound-based vitreous removal device that uses ultrasound power ranging from 27 kHz to 31 kHz, near the range of conventional phacoemulsification of 40 kHz; however, the stroke length varies between 0 µm and 60 µm.
The Vitesse hypersonic vitrectomy system (Bausch + Lomb) consists of a 23-gauge vitrectomy probe and a 33-mm long stainless steel needle with a 255-µm sized teardrop port at the tip, which oscillates with user-controlled amplitude. The Vitesse vitrectomy handpiece uses ultrasonic, harmonic needle tip movement at 28.5 kHz to
