ABSTRACT:
A surgical instrument includes a handle section and a body section operably connected thereto. The body section preferably has a first member and a second member which is slidable in relation to the first member. A jaw section is secured to the body section and includes a first jaw and a second jaw which are adapted to grasp an associated object. The jaws are axially slidable with respect to each other from a predetermined minimum distance wherein the two jaws are not in contact with each other to a predetermined maximum distance. An intraocular lens, which can be inserted in an eye with the instrument includes a lens portion and two flexible haptic elements positioned on opposite sides of the lens portion and extending radially outwardly therefrom. Each element includes a memory retaining filament connected at both ends to a periphery of the lens portion to form a closed loop and define a continuous substantially circular arc having a diameter greater than the lens diameter. The arc is curved toward the lens portion and terminates in a free end spaced therefrom. A positioning aperture is provided in a positioning member located on the periphery of the lens to prevent the aperture from moving into the line of sight if the lens undergoes decentration. A method for using the instrument for implanting the lens is also disclosed.
