Abstract: Methods and apparatus are provided for adaptively focusing a lens. In one approach, electromagnetic energy is employed to modify a shape or thickness of a lens such that its refractive power and focal length are modified. In one aspect, a lens embodying adaptive focus features requires low power, and can be adjusted quickly. One or a plurality of electromagnets can be employed to compress or separate end portions of an embedded haptic, the force from which acts to alter the shape of the haptic, thus modifying the refractive power and focal length of a lens.

Abstract: Multifocal contact lenses and methods and uses are described. The multifocal contact lenses include an optic zone. The optic zone has an aspheric power profile that provides a near vision refractive power and a distance vision refractive power, and provides an Add power that corresponds to the difference between the near vision refractive power and the distance vision refractive power. The multifocal contact lenses can improve binocular vision of presbyopic subjects by being prescribed such that the non-dominant eye contact lens is over-corrected for distance vision, and both multifocal contact lenses are under-corrected for the Add power requirement of the subject. Batches and sets of multifocal contact lenses are also described.

Abstract: Methods of correcting vision are described. The methods include inserting a lens into a corneal epithelial pocket or a pocket created between a corneal epithelium of an eye of a patient and Bowman's membrane of the eye. A lens is inserted into the pocket to correct vision. Certain methods include one or more steps of cooling the corneal epithelium, and applying an aqueous liquid to the eye. The lenses that are inserted into the pocket can include collagen, including recombinant collagen, synthetic polymeric materials, and combinations thereof.

Abstract: A contact lens having a rotational stabilization mechanism thereon, such as prism ballast, and a thickness profile that reduces the torque imparted on the lens by the action of the eyelids, especially for stabilizing toric lenses. The prism ballast is provided on one or more portions of the anterior face of the lens such that the lens body has a uniform thickness of within 10% along horizontal cross-sections. The anterior face of the lens may be segregated into a peripheral zone, an inner zone circumscribed by the peripheral zone, and a central optic zone. The prism ballast portion is provided within the inner zone, which may be further subdivided into a superior portion, an intermediate portion proximate the optic zone, and an inferior portion. The ballast portion increases in thickness along a superior-inferior line parallel to a vertical meridian, and has a substantially uniform thickness perpendicular thereto. The peripheral zone may be tapered, and have a rounded edge. The rate of thickness change across any portion of the peripheral zone is less than about 250 μm/mm.
