New intraocular lenses and methods for producing such lenses. In one embodiment, the intraocular lens includes an optic; and at least one fixation member, e.g., haptic, secured to and extending from the optic, the fixation member being made from a rotated item including a polymer, the rotated item being derived by placing an item having a thickness and the same chemical make-up as the rotated item between two surfaces so that the surfaces each contact the item and are separated by the thickness, and rotating at least a portion of one of the surfaces around an axis substantially parallel to the thickness, provided that the intraocular lens has increased tensile strength relative to a substantially identical intraocular lens made from the original item. Methods of making intraocular lenses are also included. |
