[Introduction of an aspiration-irrigation-reflow system with a special handle for extracapsular cataract operation].

A new irrigation/aspiration system consisting of an electromechanical switch and a special handle is described. The switch mechanisms acts on a tube system connected to the handle, enabling the anterior chamber to be refilled immediately via the aspiration opening, so that collapse is impossible. A further advantage is that fluid exchange is minimized, because aspiration only occurs when the pedal switch is operated. When the pedal is released the fluid is spontaneously flushed back via the aspiration opening. This results in a significant reduction in capsular and iris complications. Thanks to the special handle the fluid flushed back is practically free of lens particles.
