The present disclosure relates to an ophthalmic lens with an extended depth of field including an optical unit that includes a first surface and a second surface both centered by an optical axis and opposite to each other. At least one of the first and second surfaces is defined by a superposition of a base sag profile and a feature sag profile and includes in sequence a first zone, a second zone, and a third zone along a radial direction away from the optical axis. The first zone is designed as a freeform surface zone, and the second zone is designed as a phase transition zone. The ophthalmic lens enables patients to acquire a continuous range of vision from intermediate to far distances and also optimizes their far vision without visual interference, such that the resulting far vision correction is equivalent to that of existing monofocal ophthalmic lenses.

The present invention relates to an intraocular secondary lens (L) for insertion into the eye other than the lens that is implanted in the eye during cataract surgery so as to change the refractive power and/or to change the direction and shape of the image rays entering the eye in the patient who have undergone cataract surgery and to whom intraocular lenses are inserted. The secondary lens (L) is in a form that can be easily adhered on the primary lens (M) or the capsule (4) in which the primary lens is located and be easily removed from thereto, it has a foldable feature and contains adhesive nanostructures (6) thereon. It can be easily applied to the eye without need for structures such as hole, notch, foot etc. on the primary lens (M) with the invention by means of the nano structures (6) on the secondary lens. Said secondary lens (L) may be in the form of normal refractive, diffractive, accommodative, and toric, trifocal, multifocal, or combinations thereof, or optionally may carry devices with different optical properties.

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 multi-piece IOL assembly is provided that includes a platform and an optic. The platform has an inner periphery surrounding an inner zone of the platform. The optic has an optical zone, an outer periphery and a retention mechanism disposed on the outer periphery. The optic is configured to be disposed in the inner zone of the platform and to extend to a location between the inner periphery and the outer periphery of the platform to be secured to the platform at the location. The platform can be secured to an inner periphery of the eye or can be formed into a natural lens by cutting the lens using a laser or other energy source.

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 peripheral 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.

An implantable or wearable lens for ophthalmic use, having a front surface and a rear surface, wherein at least one surface of said front surface and rear surface has an aspherical refractive profile with circular or rotational symmetry, or with cylindrical or non-rotational symmetry, with respect to the optical axis, and having a geometric elevation z(r) defined by a series expansion of Forbes polynomials, wherein said refractive profile generates an enhancement of the wavefront W(r) emerging from the lens such as to extend the depth of field thereof progressively and continuously in a power range between −1.0 D and 4.0 D.

An ophthalmic multifocal lens, and a method of manufacturing same, at least comprising focal points for near, intermediate and far vision. The lens comprises a light transmissive lens body providing a refractive focal point, and a periodic light transmissive diffraction grating, extending concentrically over at least part of a surface of the lens body and providing a set of diffractive focal points. The diffraction grating is designed to operate as an optical wave splitter, the refractive focal point providing the focal point for intermediate vision and the diffractive focal points providing the focal points for near and far vision. The diffraction grating has an optical transfer function comprising a continuous periodic phase profile function having an argument modulated as a function of the radial distance (r) to the optical axis of the lens body, thereby tuning the light distribution in the focal points.

A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.

Apparatuses, systems and methods for providing improved ophthalmic lenses, particularly intraocular lenses (IOLs), include features for providing a range of vision. Chromatic aberrations may be reduced at near, distance, and intermediate vision.
