    Abstract: The embodiments disclosed herein include improved toric lenses and other ophthalmic apparatuses (including, for example, contact lens, intraocular lenses (IOLs), and the like) that includes one or more refractive angularly-varying phase members, each varying depths of focus of the apparatus so as to provide an extended tolerance to misalignments of the apparatus. Each refractive angularly-varying phase member has a center at a first meridian (e.g., the intended correction meridian) that directs light to a first point of focus (e.g., at the retina of the eye). At angular positions nearby to the first meridian, the refractive angularly-varying phase member directs light to points of focus of varying depths and nearby to the first point of focus such that rotational offsets of the multi-zonal lens body from the center of the first meridian directs light from the nearby points of focus to the first point of focus.

    Abstract: A multifocal diffractive lens comprises a multifocal diffractive structure coupled to a refractive component. The refractive component comprises at least one curved surface. The multifocal diffractive structure comprises a first plurality of substantially monofocal echellettes having a first optical power for near vision correction and a second plurality of substantially monofocal echellettes for far vision correction. The first plurality of substantially monofocal echellettes combined with the second plurality of substantially monofocal echellettes can provide a multifocal diffractive profile having decreased light scatter, chromatic aberration, and diffraction to non-viewing orders such that dysphotopsia is substantially inhibited. A third plurality of substantially monofocal echellettes having an intermediate optical power can be combined with the first plurality of substantially monofocal echellettes and the second plurality of substantially monofocal echellettes.

    Abstract: Ophthalmic lenses and methods for their design and use involve displacement functions based on the sum of a continuous cosine function and a continuous sine function, optionally over a plurality of echelettes. Exemplary monofocal and multifocal diffractive ophthalmic lenses provide reduced light scatter and/or improved light energy distribution properties. Such properties can be provided by diffractive profiles, often having subtlety shaped echelettes with appropriately curving profiles. Light scatter may be generated by the sharp corners associated with vertical steps between adjacent conventional diffractive echelettes. Smooth diffractive profiles of the invention reduce light scatter. Light energy directed toward non-viewing diffractive orders may have a unwanted effects on vision quality. Diffractive profiles as described herein may limit the light energy in certain, selected orders, thereby improving viewing quality and mitigating unwanted effects such as dysphotopsia. Diffractive profiles may also vary the light energy distributed between individual echelettes, providing additional advantages in various viewing situations.

    Abstract: Improved systems and methods for determining ocular scattering are provided. These systems and methods can be used to quantify ocular scattering before and/or after a wide variety of different ophthalmic diagnostic procedures, and various surgical and non-surgical treatments. One embodiment provides a system and method for determining ocular scattering that uses two light detectors, with one detector configured to detect light over a relatively narrow angular range, and the other detector configured to detect light over a relatively large angular range. The data from the narrow angular range and the large angular range can then be analyzed to determine a measurement of ocular scattering.

    Abstract: 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.

    Abstract: An intraocular lens for reducing aberrant optical effects includes a substantially oval, elliptical, or rectangular optic with an anterior surface, a posterior surface and a peripheral region/zone disposed about a central optical axis and a plurality of haptics coupled to the optic. The peripheral region/zone has an inflection region/transition area that is inclined with respect to the anterior surface at an angle between about 40 degrees and 120 degrees with respect to the optical axis. The thickness at the edge of the IOL is less than or about 0.03 mm.
