A method of applying a contact lens to an eye of a subject can include: applying an ophthalmic composition to the contact lens, wherein the ophthalmic composition includes a colorant that temporarily colorizes the contact lens; and positioning the colorized contact lens onto a correct position of the eye while visualizing the colorized contact lens. A method of removing a contact lens from an eye of a subject can include: applying an ophthalmic composition to the contact lens while located on the eye of the subject, wherein the ophthalmic composition includes a colorant that temporarily colorizes the contact lens; and removing the colorized contact lens from the eye while visualizing the colorized contact lens.

A continuous additive fabrication system comprises a bath of photopolymer resin and a light source assembly having a light source and a motorized variable aperture. The light source assembly is operable to generate a focus point in the bath of photopolymer resin, the shape of the focus point at a curing plane within the bath of photopolymer resin corresponding to the shape of the motorized variable aperture. The continuous additive fabrication system further comprises a platform configured to support a build object and a drive mechanism (coupled to at least one of the platform and the light source assembly) configured to continuously move the curing plane through the bath of photopolymer resin. A size and/or shape of the motorized variable aperture is changed while the curing plane in continuously moved through the bath of photopolymer resin.

Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a mask adapted to increase depth of focus. The method of manufacturing the implant can include positioning the mask with an aperture on a protruding pin of a positioning mold portion. The protruding pin can be configured to center the mask in the intraocular lens.

An optical device comprising an optical hydrogel with select regions that have been irradiated with laser light having a pulse energy from 0.01 nJ to 50 nJ and a wavelength from 600 nm to 900 nm. The irradiated regions are characterized by a positive change in refractive index of from 0.01 to 0.06, and exhibit little or no scattering loss. The optical hydrogel is prepared with a hydrophilic monomer.

The present invention provides an intraocular lens, including a first poly-p-xylylene film, a second poly-p-xylylene film and a liquid drop. The liquid drop is disposed between the first poly-p-xylylene film and the second poly-p-xylylene. The present invention further provides a method of forming the same.

An electronic device can comprise a first electronic module; a second electronic module; and a hermetic electric interconnect to hermetically couple them. The hermetic electric interconnect can comprise a bottom metal layer; a bottom insulating layer, deposited on the bottom metal layer to insulate the bottom metal layer; an interconnect metal layer, deposited on the bottom insulating layer, and deposited to form a bottom sealing ring; and patterned to form electrical connections between contact pads, and to form a middle sealing ring; a patterned top insulating layer, deposited on the interconnect metal layer to insulate the interconnect metal layer; and patterned to form feedthrough holes; and a top metal layer, deposited on the top insulating layer to start forming contacts by filling the feedthrough holes; and patterned to complete forming contacts through the feedthrough holes, to form a separate barrier layer, and to complete forming the top sealing ring.

Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.

An ophthalmic lens for providing enhanced vision includes a finished optic comprising a base optic and a membrane. The base optic has an anterior surface and an opposing posterior surface, at least one of the surfaces having a first value of a surface quality parameter. The base optic also includes a membrane including an inner surface and an outer surface, the inner surface covering one or more of the surfaces of the base optic. The outer surface has a second value of the surface quality parameter, wherein the second value is greater than the first value.
