ABSTRACT:
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.
