The present invention relates to a device for fracturing and removing ocular lenses. The device mainly comprises a rotational screw drill, a sleeve and a hydraulic suction system. The rotational screw drill has reversed conical propellers which help to grind the particles. The rotational screw drill is housed in a sleeve, which comprises a rigid cylinder and a suction cup. The suction cup has a bell or funnel shape with an elliptical cross-section. Finally, the hydraulic suction system is key for the present invention performance. Also, the invention relates to a method comprising the steps of breaking, splitting the cataract or lens tissue and simultaneously or subsequently grinding the particles inside the sleeve by means of the rotational screw drill and the sleeve, and finally removing them from the medium via the sleeve by means of a hydraulic suction system.
