This invention discloses methods and apparatus for providing an ophthalmic lens with a stacked integrated component device for function. In some embodiments, the stacked integrated component device may contain an energy source capable of powering an electrical component incorporated into the lens.

Implantable corneal and intraocular implants such as a mask are provided. The mask can improve the vision of a patient, such as by being configured to increase the depth of focus of an eye of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a transition portion that surrounds at least a portion of the aperture. This portion can be configured to switch from one level of opacity to another level of opacity through the use of a controllably variable absorbance feature such as a switchable photochromic chromophore within a polymer matrix.

Contact lenses incorporate mask lens designs that at least one of slow, retard or preventing myopia progression. The lens includes a first zone at a center of the lens; at least one peripheral zone surrounding the center and having a dioptric power that is different than that at the center; and an opaque mask beginning at a radial distance from the center, thereby providing a lens power profile having substantially equivalent foveal vision correction to a single vision lens, and having a depth of focus and reduced retinal image quality sensitivity that slows, retards, or prevents myopia progression.

Systems and methods are provided for improving overall vision in patients suffering from a loss of vision in a portion of the retina (e.g., loss of central vision) by providing a dual optic intraocular lens which redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The intraocular lens can include a redirection element (e.g., a prism, a diffractive element, or an optical component with a decentered GRIN profile) configured to direct incident light along a deflected optical axis and to focus an image at a location on the peripheral retina. Optical properties of the intraocular lens can be configured to improve or reduce peripheral errors at the location on the peripheral retina. One or more surfaces of the intraocular lens can be a toric surface, a higher order aspheric surface, an aspheric Zernike surface or a Biconic Zernike surface to reduce optical errors in an image produced at a peripheral retinal location by light incident at oblique angles.

Apparatus is provided, including an external device, including a mount, placed in front of an eye, and a laser which emits toward the eye radiation that is outside of 380-750 nm. The apparatus additionally includes an intraocular device which is implanted entirely in the eye, and includes an energy receiver, a plurality of stimulating electrodes, a plurality of photosensors, and driving circuitry coupled to the energy receiver and to the photosensors, and configured to drive the electrodes to apply currents to a retina of the eye in response to the signals from the photosensors. The photosensors are (a) generally insensitive to the energy from the laser, and (b) generally sensitive to visible light. Other applications are also described.

A method for reducing the transmittance of ultraviolet radiation through an intraocular lens to 10% or less at 370 mm Additionally, a method for preventing the transmittance of at least 90% of ultraviolet radiation at 370 nm through a foldable intraocular lens comprising: (a) incorporating a monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety into at least one polymer and (b) forming the polymer into a material suitable for use as an intraocular lens, wherein the monomer comprising a 4-(4,6-diphenyl-1,3,5-triazin-2-yl)-3-hydroxyphenoxy moiety comprises 0.10 to 0.15 weight percent of the overall dry polymer.

Embodiments disclosed herein are directed to intraocular lens systems includes at least one intraocular lens device and methods of using the same. The at least one intraocular lens device includes one or more photodetectors and an intraocular lens exhibiting a modifiable focal length. The one or more photodetectors are configured to detect light that is used to determine a presence of the object or the apparent object distance. The focal length of the intraocular lens can be modified depending on the determined presence of the object or the apparent object distance.

A mask is provided that is configured to increase the depth of focus of a patient. The mask can include an aperture configured to transmit along an optical axis substantially all visible incident light. The mask can further include a portion surrounding at least a portion of the aperture. The portion may be configured to be substantially opaque to visible electromagnetic radiation and be substantially transparent to electromagnetic radiation transmitted from an ocular examination device (e.g., substantially transparent to at least some non-visible electromagnetic radiation with a wavelength between about 750 nm and about 1500 nm).

System, ophthalmic lens, and method for extending depth of focus includes an optic having a clear aperture disposed about a central axis. The optic includes a first surface and an opposing second surface. The first and second surfaces are configured to introduce an asymmetric aberration to the eye while maintaining the in-focus visual acuity.

Ophthalmic implants, their methods of use and manufacture. The implants may include a transparent optic portion and a peripheral non-optic portion coupled to the optic portion. The transparent optic portion may be made of a transparent optic material adapted to allow visible light to pass therethrough, and the peripheral non-optic portion may be made of a light absorbing material adapted to absorb visible light.
