The present disclosure is directed to lenses, devices, methods and/or systems for addressing refractive error. Certain embodiments are directed to changing or controlling the wavefront of the light entering a human eye. The lenses, devices, methods and/or systems can be used for correcting, addressing, mitigating or treating refractive errors and provide excellent vision at distances encompassing far to near without significant ghosting. The refractive error may for example arise from myopia, hyperopia, or presbyopia with or without astigmatism. Certain disclosed embodiments of lenses, devices and/or methods include embodiments that address foveal and/or peripheral vision. Exemplary of lenses in the fields of certain embodiments include contact lenses, corneal onlays, corneal inlays, and lenses for intraocular devices both anterior and posterior chamber, accommodating intraocular lenses, electro-active spectacle lenses and/or refractive surgery.

Ophthalmic devices, such as contact lenses, may incorporate myopia control optics in combination with therapeutic agents also known to control myopia to create a drug delivery mechanism to inhibit or arrest the progression of myopia in individuals. Any number of contact lenses incorporating myopia control optics may be combined with a therapeutic agent such as atropine, atropine sulphate monohydrate, and/or pirenzepine.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for providing improved extended depth of focus lenses. Exemplary ophthalmic lenses can include an optic including a diffractive profile including multiple rings, with the rings having step heights corresponding to a desired performance of the optic and configured to reduce adverse optical effects of the diffractive profile.

Systems and methods for non-invasively assessing ciliary muscle accommodative potential in phakic eyes may include receiving a plurality of signals generated by a plurality of bipolar electrodes during a ciliary muscle assessment procedure, each of the plurality of signals indicating an electrical field associated with a patient's ciliary muscle, and analyzing the signals to evaluate the patient's ciliary muscle accommodative potential.

Dynamic contact lenses fabricated with a dynamic portion that extends outward from the peripheral portion are disclosed. When worn on an eye the dynamic portion forms a tear lens for correcting vision. The dynamic portion can also be configured to provide a dynamic tear lens that changes optical power with forces applied by eyelids. The dynamic portion can be configured to assume a conforming configuration and at least one non-conforming configuration, or can be configured to assume at least two non-conforming configurations. The dynamic contact lenses can be used for correcting vision such as correcting presbyopia.

Multifocal intraocular lens with extended depth of field that comprises, in at least one of the surfaces (2), a small zone with a multifocal profile with a defined optical axis (3) and, in the peripheral region and coaxial to the multifocal zone, a ring-shaped opaque mask (1) that partially or totally block light to produce a small aperture effect and, therefore, the multifocal profile has a radius equal or larger than the internal radius of the mask (1), and there is at least one transition between focal zones or one diffractive step inside the internal radius of the mask (1).

Methods and apparatus to form biocompatible energization elements are described. In some embodiments, the methods and apparatus to form the biocompatible energization elements involve forming cavities comprising active cathode chemistry. The active elements of the cathode and anode are sealed with a laminate stack of biocompatible material. In some embodiments, a field of use for the methods and apparatus may include any biocompatible device or product that requires energization elements.

Ophthalmic lenses incorporate multifocal properties for the purpose of slowing, retarding, controlling or preventing myopia development or progression, correcting presbyopic vision or allowing extended depth of focus. The lens has electronically controlled adjustable focus where the change in focus oscillates so rapidly that it is imperceptible to human vision.

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.

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.
