A multifocal ophthalmic lens has a surface that varies across at least a portion of the lens to form a surface power map. The surface power map comprises a spiral, with a power that varies substantially periodically both radially outwards from and angularly about an optical axis of the lens. A period of the radial variation is greater than 100 microns and a period of the angular variation is greater than 6 degrees. Methods of making and using the multifocal ophthalmic lens are also described.

A method and system provide an ophthalmic device. The ophthalmic device includes an ophthalmic lens having an anterior surface, a posterior surface, at least one diffractive structure and at least one base curvature. The at least one diffractive structure for provides a first spherical aberration for a first focus corresponding to at least a first focal length. The at least one base curvature provides a second spherical aberration for at least a second focus corresponding to at least a second focal length. The first spherical aberration and the second spherical aberration are provided such that the first focus has a first focus spherical aberration and the second focus has a second focus spherical aberration. The first focus spherical aberration is opposite in sign to the second focus spherical aberration.

An ophthalmic lens comprising: at least one first optical zone with a first axis, the at least one first optical zone being configured such that, in use with an eye, at least a portion of light passing through the at least one first optical zone is refracted to a first focal point on the first axis; and at least one second optical zone configured such that, in use with the eye, at least a portion of light passing through the at least one second optical zone is refracted to one or more focal points positioned off-axis relative to the first focal point and on at least one focal plane different than a focal plane corresponding to the first focal point; wherein the at least one second optical zone is configured such that the light extending beyond the one or more focal points provides extended depth of focus.

A lens for an eye that includes a zone with a first power profile for images received by the retina on the fovea, a zone with a second power profile for images received by the peripheral retina on the nasal side and a zone with a third power profile for images received by the peripheral retina on the temporal side. The first power profile is selected to provide clear or acceptable vision and the second and third power profiles are selected to affect the peripheral image position.

An optical device having an optical axis. The device includes at least one surface with at least two meridians, at least one portion of which forms, seen face-on, at least one spiral segment the central point of which is on the optical axis. Each spiral segment defining meridians of different optical powers. The focus obtained extends over a tubular region.

A method to provide EDoF ophthalmic lens designs based on continuous periodic refractive power profile includes: providing an underlying optical correction lens surface curve where needed; defining a periodic power map to provide a correction which emphasizes an individual use case, while still providing a functional DoF for other uses; mapping the periodic power curve to a physical lens curvature profile; where there is an underlying optical correction, superimposing the physical lens curvature profile over the underlying optical correction; and providing the combined underlying optical correction, if any, and physical lens curvature profile to physically manufacture an EDoF ophthalmic eyewear.

Apparatuses, systems, and methods for providing improved intraocular lenses (IOLs) and other refractive treatment modalities involve fabricating the IOL or developing the treatment based on a refractive profile. Exemplary techniques include obtaining a base wavefront power profile corresponding to a theoretical lens, adding a second wavefront profile defined by the combination of one or more zones described by a cosine function to obtain a final wavefront power profile, determining a refractive profile based on the final wavefront power profile, and fabricating the intraocular lens or determining the treatment based on the refractive profile.

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).

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.

The present invention relates to a contact lens for presbyopia and, more specifically, to a contact lens for presbyopia, providing both a far-distance vision area and a near-distance vision area in one contact lens, and continuously forming a lens magnification of the far-distance vision area and the near-distance vision area of the dominant eye and the non-dominant eye while changing the sizes of the far-distance vision area and the near-distance vision area of two eyes according to the dominant eye and the non-dominant eye, such that an intermediate-distance area is partially overlapped, thereby continuously providing a near-distance vision area at a far distance by a neural summation phenomenon that selects a clearly visible image in both eyes.
