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.
