Popis: In the 1970s a cutting device into which an infusion and an aspiration channels were integrated, the so-called vitreous infusion suction cutter (V.I.S.C), was used for the first time for the removal of the vitreous body. These cutting systems have continued to constantly evolve since then; however, sonic energy remained reserved for anterior segment surgery for a long time. In 2020, this form of energy could also be used for the posterior segment in form of Vitesse™. In this liquification technique, ultrasonic energy is transferred to a single, large inner lumen design that mechanically vibrates the needle's port. These high-speed vibrations shear the vitreous body at the port edges before it enters the needle. This mechanism reduces traction to a minimal level and enables faster aspiration at lower vacuum levels compared to conventional cutters. These advantages can promote a safer and more efficient vitreoretinal surgery.
