    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.

    Abstract: Methods for slowing progression of myopia or hyperopia of human patients include a step of providing contact lenses. The contact lenses have two or more refractive powers. A first refractive power provides clear visual acuity and a second refractive power provides a defocused retinal image to the human patient. The methods involve providing first and second sets of the contact lenses, the contact lenses of the second set have a different optical design than the contact lenses of the first set. With the present methods, an eye care practitioner is able to select one or more contact lenses from the second set of contact lenses based on one or more ocular parameters of the patient, one or more responses of the patient to the contact lens of the first set, or both, to provide an improved clinical benefit to the patient compared to the benefit provided by the first set of contact lenses.

    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.
