A capsulectomy apparatus which comprises a console, a handpiece and a needle. The handpiece operates from a vibrating transducer which drives a rod within the sleeve of the needle for actively engageing the anterior lens capsule which is to be severed. The head of the needle which engages and cuts the anterior lens capsule of the eye has a specific angular relationship with the rod within the needle. Also, the cutting edges and surfaces associated with the head of the needle have a specific configuration for enhancing the cutting quality of the apparatus. The needle is disposable and specifically configured to be removeably affixed to the handpiece.
