    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: 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: An intraocular lens for providing a subject with vision at various distances includes an optic having a first surface with a first shape, an opposing second surface with a second shape, a multifocal refractive profile, and one or more diffractive portions. The optic may include at least one multifocal diffractive profile. In some embodiments, multifocal diffractive and the multifocal refractive profiles are disposed on different, distinct, or non-overlapping portions or apertures of the optic. Alternatively, portions of the multifocal diffractive profiles and the multifocal refractive profiles may overlap within a common aperture or zone of the optic.

    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. 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 1.0 D (diopters).

    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 a freeform-polynomial surface area that establishes a band of operational meridian for the apparatus to an intended correction meridian. The freeform-polynomial surface area is defined by a mathematical expression comprising a combination of one or more polynomial expressions (e.g., Chebyshev-based polynomial expression, Zernike-based polynomial expression, etc.) each having a distinct complex orders.
