ABSTRACT:
In accordance with the present invention, an ophthalmic surgical instrument for removing the lens of an eye includes a handle adapted for support in the hand of the user. An elongated tubular member having first and second ends is attached to the handle. The elongated tubular member includes an aperture communicating with the interior of the elongated tubular member and which is disposed between the first and second ends thereof. An arcuate portion of the elongated tubular member extends from the aperture to the second end thereof for receiving the lens. An actuator is mounted to the handle for movement between a forward position and a rearward position with respect to the handle. An elongated rod is disposed within the elongated tubular member and is attached to the actuator, such that movement of the actuator to the forward position causes the rod to extend from the elongated tubular member aperture toward the second end of the elongated tubular member to engage the lens thereby lodging the lens between the second end of the rod and the second end of the elongated tubular member for removal of the lens from the eye. Movement of the actuator to the rearward position causes the rod to retract within the elongated tubular member when not engaging the lens.
