    摘要： The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. In an embodiment, an ophthalmic apparatus (e.g., a toric lens) includes one or more angularly-varying phase members comprising a diffractive or refractive structure, each varying the depths of focus of the apparatus so as to provide an extended tolerance to misalignment of the apparatus when implanted in an eye. That is, the ophthalmic apparatus establishes an extended band of operational meridian over the intended correction meridian.

    摘要： The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) and associated method for their design and use. The apparatus includes one or more optical zones, including an optical zone defined by a polynomial-based surface coincident at a plurality of meridians having distinct cylinder powers, wherein light incident to a given region of each of the plurality of meridians, and respective regions nearby, is directed to a given point of focus such that the regions nearby to the given region direct light to the given point of focus when the given meridian is rotationally offset from the given region, thereby establishing an extended band of operation, and wherein each of the plurality of meridians is uniformly arranged on the optical zone for a same given added power (in diopters) up to 1.0D (diopters).
