ABSTRACT:
An ophthalmic instrument including an elongated tube having proximal and distal end portions, a distal end and an elongated passage opening at a distal opening at the distal end. The distal end portion is sized to be received through an incision into the eye. An elongated member having a resiliently deformable end portion is at least partially received in the elongated passage of the tube. The distal end portion of the inner member has a curved configuration in a relaxed condition and is capable of performing a function within the eye. The tube and the inner member are relatively movable longitudinally so that the distal end portion of the inner member can be caused to project through the distal opening a variable amount to change the length of the arc of the curved configuration projecting from the distal opening. A hollow ultrasound needle is positioned in the inner member which is movable relative to the needle.
