new intraocular lenses and methods for producing such lenses are included . 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 compressed item having a compressed thickness and made of a polymer selected from the group consisting of methyl methacrylate homopolymers , methyl methacrylate - containing copolymers and mixtures thereof , the compressed item being derived by subjecting an item having a thickness to compression , preferably along an axis substantially parallel to the thickness , to reduce the thickness , provided that the compressed item has increased tensile strength relative to the item and is substantially no less intraocular lens manufacturable than is the item .
