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 method and system provide an ophthalmic lens including a lens body having a chamber therein, a reservoir module coupled with the lens body and an optical fluid. At least part of the lens body is flexible. The reservoir module includes a reservoir and a heat sensitive portion bordering the reservoir. The reservoir has a reservoir volume and is fluidically connected with the chamber. The heat sensitive portion has a shape responsive to a temperature of at least forty five degrees Celsius such that the reservoir volume changes in response to at least part of the heat sensitive portion reaching the temperature. The optical fluid resides in the chamber and the reservoir. A change in the reservoir volume flows a portion of the optical fluid between the reservoir and the chamber such that the flexible portion of the lens body undergoes a shape change corresponding to a base power change.

Prosthetic capsular devices (e.g., bag, bowl, housing, structure, cage, frame) include technology devices such as a computer, virtual reality device, display device, WiFi/internet access device, image receiving device, biometric sensor device, game device, image viewers or senders, GPSs, e-mail devices, combinations thereof, and/or the like. The technology devices can be used in combination with an intraocular lens. The output from the technology device(s) can be fed to the retina of the user to provide a visual image, can be otherwise connected to the user, and/or can be used to control the properties of the intraocular lens or of the prosthetic capsular device. Wearable technology that provides biometric data, such as blood glucose levels, body temperature, electrolyte balance, heart rate, EKG, EEG, intraocular pressure, sensing ciliary muscle contraction for accommodation stimulus, dynamic pupil change and retinal prostheses, combinations thereof, and the like can assist in technology-assisted health care functions.

A method for reducing the transmittance of ultraviolet radiation through an intraocular lens to 10% or less at 370 nm by (a) polymerizing a mixture comprising: at least one first monomer and a second monomer comprising a trisaryl-1,3,5-triazine moiety, (b) forming an optic portion from the copolymer wherein the second monomer is present in about 0.10 to about 0.20 percent by weight of the overall polymer and wherein the optic portion of the intraocular lens displays essentially the same physical properties such as, for example, refractive index as the optic portion of the intraocular lens formed from the polymerized mixture of (a) without the second monomer, but otherwise identical conditions. 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.

This disclosure relates compositions comprising upconverting core-shell nanocrystals and photoactive compositions and methods using these compositions to modify treat myopia and other ocular conditions. In some cases, the methods use near infrared irradiation to adjust the refractive power of light adjustable intraocular lenses.

A method for adjusting a light adjustable lens in an optical system includes providing a light adjustable lens in an optical system; providing an ultraviolet light source to generate an ultraviolet light; and irradiating the generated ultraviolet light with a light delivery system onto the light adjustable lens with a center wavelength and with a spatial irradiance profile to change a dioptric power of the light adjustable lens by changing a refraction of the light adjustable lens in a refraction-change zone, thereby causing a wavefront sag, defined as half of a product of the change of the dioptric power and the square of a radius of the refraction-change zone, to be within 28% of its maximum over an ultraviolet spectrum.

At least part of the lens body is flexible. The reservoir module includes a reservoir and a heat sensitive portion bordering the reservoir.

An ophthalmic lens for myopia control comprising patterns or masks which block and/or attenuate light (e.g., by amplitude modulation). The amplitude modulation may be binary, for example, where zero amplitude means absorption or blocking of light and a value of one means that light may be transmitted through the lens without change (e.g., without significant change). Alternatively, in some embodiments, the amplitude modulation may not be binary.

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 piggyback lens which in combination with the cornea and an existing lens in the patient's eye redirects and/or focuses light incident on the eye at oblique angles onto a peripheral retinal location. The piggyback 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 piggyback lens can be configured to improve or reduce optical errors at the location on the peripheral retina. One or more surfaces of the piggyback 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. One or more surfaces of the piggyback lens can be faceted.
