The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves autoclaving, in a sealed lens package, a silicone hydrogel contact lens having a base coating of polyacrylic acid thereon in an aqueous solution in the presence of a water-soluble, crosslinkable hydrophilic polymeric material having epoxide groups, for a period of time sufficient to covalently attach the crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one epoxide group and one of the carboxyl groups on and/or near the surface of the silicone hydrogel contact lens.

A contact lens with a sensor region are described. The contact allows for normal vision and a concentric ring around the vision area of the lens includes one or more sensors for detecting changes in the interocular pressure of the eye. The data may be scanned using a camera, or in some embodiments, the data may be transmitted using a micro antenna in the sensing region. The data may be analyzed using a software application on a cell phone or other computing device.

The present invention provides a new method for producing a lens to be fitted to an eye in a simple manner at a low cost. In order to achieve the aforementioned object, the present invention provides a method for producing a lens to be fitted to an eye, including the step of: hydrophilizing a surface of a polymer lens by reacting with a compound radical, wherein the compound radical is a radical containing one element selected from the group consisting of Group 15 elements and Group 16 elements, and a Group 17 element.

An electrically-controlled optical device intended to be placed in front of a user's eye, the electrically-controlled optical device being an ophthalmic device, the electrically-controlled optical device comprising: a front shell defining a front surface and a back surface opposed to the front surface, the front shell comprising a slab, at least one functional layer arranged on the back surface and one primer layer, said primer layer being arranged between the at least one functional layer and the slab; and an electrically-controlled object facing the back surface of the front shell wherein the primer layer is conformed such that the electrically-controlled optical device is mechanically resistant to an impact energy of at least 200 mJ.

A biomedical device including an energy source, an electro-active device operatively connected to the energy source, circuitry configured to control operation of the electro-active device, at least one barrier layer including at least one inorganic material surrounding the energy source, electro-active device and circuitry, and at least one molded layer surrounding the at least one barrier layer. A method for encapsulating electronic components of an electro-active biomedical device in a protective envelope containing a barrier layer including at least one inorganic compound, and a molded polymer overcoat.

Methods are disclosed for manufacturing a coated contact lens that comprises a polymeric lens body comprising an acid group, a first coating polymer comprising a first amine group ionically bound to the acid group, and a second coating bound to the first coating polymer through covalent linkage between a nitrogen atom of a second amine group on the first coating polymer and an amine-reactive group of the second coating polymer. In some examples the lenses exhibit improved surface properties compared to uncoated lenses, such as reduced adhesion, increased wettability, increased lubricity, and/or increased lipid resistance.

A system for providing electrical energy to an implanted device or to a device attached to a body. The system includes one or more permanent magnets attached to or implanted in a first body part and one or more inductor(s) attached to or implanted in a second body part. The inductor(s) are electrically couplable to the implanted device for providing the implanted device with electrical currents flowing in the one or more inductor(s) in response to changes in the position and/or orientation of the permanent magnet(s) relative to the position and/or orientation of the inductor(s). The system may include a current rectifier for rectifying electrical currents provided by the inductor(s). The system may also include a charge storage device electrically coupled to the current rectifier for storing electrical energy received from the current rectifier.

A method of preparing and using a contact lens is disclosed. In one step, a light-absorbing dye solution, comprising a light-absorbing dye disposed in a solution, is dispensed onto a contact lens. In another step, the light-absorbing dye is reacted with the contact lens so that the contact lens permanently contains the light-absorbing dye. The transmission of light of a certain wavelength through the contact lens is reduced due to the reacted light-absorbing dye permanently contained within the contact lens.

A smart contact lens includes a contact lens, a nanostructures layer, a first sensor, a connector, and a smart module. The nanostructures layer may be anti-bacterial. The smart contact lens may be worn on an eye or may be implanted within an eye. The nanostructures layer is fabricated by depositing a colloidal dispersion onto an electrostatically-coated substrate. The colloidal dispersion is then removed and nanoholes are etched. The electrostatic coating is removed and a biocompatible material is spin-coated onto the substrate. Upon removal, a quasi-randomly distributed nanostructures layer forms.
