Abstract
An ophthalmic surgical device for macerating the lens nucleus in the eye and for removing particles of the macerated lens nucleus from the eye of a living being, includes a hand-held housing with a head piece attached at one axial end of the housing and supporting a guide tube. Disposed in the guide tube is a tubular probe which is operatively connected to a motor drive and projects beyond the guide tube with its tip to carry a cutting element in form of at least two rotatable wing-like blades oriented approximately transversely to the longitudinal axis of the guide tube. By means of the drive, the tubular probe is rotatable relative to the stationary guide tube about the longitudinal axis and movable at a high frequency in direction of the longitudinal axis.
