Apparatus and systems for an ophthalmic device having alignment features that aid assembly of a liquid filled layered stack are disclosed herein. An example apparatus may include first, second, and third optical elements arranged in a stack, with each optical element including alignment and separation features. The alignment and separation features may form an optic region and a dam region. The optic region encircles an optical axis of each of the optical elements. The dam region includes a first dam formed due to the first and second optical elements being in contact, and a second dam formed due to the second and third optical elements being in contact, wherein the dam region determines an optic region gap width.

A voltage driver can be operated to power an electrowetting lens of an eye-implantable or eye-mountable device. The voltage driver includes a first charge pump that outputs a first voltage having a first polarity and a second charge pump that outputs a second voltage having a second polarity, where the second polarity is an opposite polarity of the first polarity. The voltage driver can be operated to charge the electrowetting lens by coupling the first charge pump to the electrowetting lens and, after charging the electrowetting lens, discharge the electrowetting lens by coupling the second charge pump to the electrowetting lens. In operation, charging and discharging the electrowetting lens adjusts an optical power of the electrowetting lens and can thus adjust an optical power available for vision when the electrowetting lens is implanted in or mounted on an eye.

Apparatuses, systems, and methods directed to reducing negative dysphotopsia in an individual's eye. Such apparatuses, systems, and methods may include determining an angle kappa of an individual's eye. Such apparatuses, systems, and methods further include tilt adjustable intraocular lenses.

An intraocular lens (IOL) includes one or more haptic structures coupled to hold the IOL (100A) system in an eye. The IOL also includes one or more mechanical-to-electrical transducers (107) that detect mechanical changes in the eye and, in response to the mechanical changes, output an electrical signal. An accommodation actuator (101) is electrically coupled to the one or more mechanical-to-electrical transducers, and in response to the electrical signal the optical power of the accommodation actuator changes.

Embodiments of a modulable absorption light adjustable lens (MALAL) comprise a light adjustable lens that is capable of changing its optical properties upon an adjusting irradiation, including a photo-modifiable material; and a modulable absorption front protection layer, including a modulable absorption compound whose absorption properties can be modulated with a modulating stimulus. Other embodiments include a method of adjusting an optical property of a modulable absorption light adjustable lens, the method comprising: reducing an absorption of a modulable absorption compound of a modulable absorption front protection layer of the MALAL by a modulating stimulus, the MALAL having been previously implanted into an eye; and changing an optical property of a light adjustable lens of the MALAL by applying an adjusting irradiation.

Provided is an intraocular lens including a lens body having a back surface disposed on a retinal side and a front surface disposed on a corneal side, wherein an entire back surface is shaped in such a way as to protrude from a peripheral edge of the back surface toward the retinal side in a direction of an optical axis, in a shape of a truncated cone, and the front surface has any of the following shapes (i) to (iii); (i) the front surface is shaped in such a way as to start to be recessed toward the retinal side in the direction of the optical axis when viewed toward a center from a peripheral edge of the front surface, (ii) the front surface is shaped in such a way that an initial part from the peripheral edge of the front surface toward the center is flat, (iii) the front surface is shaped in such a way as to start to protrude toward the corneal side in the direction of the optical axis when viewed toward the center from the peripheral edge of the front surface, but a rate of rise of a protrusion from the peripheral edge of the front surface is smaller than a rate of rise of a protrusion from the peripheral edge of the back surface.

A substrate carries electrical components. It is bent into a non-planar shape to fit into a contact lens. For example, the substrate may be constructed from a flexible circuit board. The circuit board has certain regions for mounting electrical components. The flexible circuit board is bent into a three-dimensional shape that fits into the contact lens. The regions used to mount electrical components remain flat.

The present disclosure provides an ophthalmic lens (such as an IOL) that is designed to enhance depth of focus for intermediate vision performance, while maintaining distance vision. The lens may include an optic having an anterior surface and a posterior surface disposed about an optical axis. One of the surfaces (e.g., the anterior surface) may have a surface profile involving a superposition of at least three structures or profiles, including a base structure, a phase shift structure having an inner region, an outer region and a transition region, and a zonal structure having an inner power zone and an outer transition zone.

A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

Eyewear is provided including a frame, and a camera connected with the frame, in which the camera is configured to be controlled by a remote controller. The camera may be configured to capture video and/or a photo. The eyewear may include data storage, and the camera may be connected to the data storage. A wrist watch may be configured to act both as a time piece and a controller of the camera. The eyewear may also include a heads up display and/or a video file player. The eyewear may also include an electro-active lens.
