What is claimed is:
1. A method of implanting an intraocular lens which comprises, making a surgical incision in the eye, inserting at least a portion of an intraocular lens assembly in the anterior chamber of the eye, pre-positioning at least one haptic associated with said lens assembly so that it is located at substantially the final position in said anterior chamber which it will occupy when the optic section of said lens assembly is in a position to function as a replacement for a surgically removed natural lens of the eye or portion thereof, and thereafter surgically removing at least a portion of said natural lens.
