A device for optically representing intraocular pressure, having an arrangement which is implanted into the eye with a membrane that curves outwards when the intraocular pressure changes, and a contact surface, these altering the polarization for a spectral range of incident and reflected light in the region of their contact with one another, as well as a read-out arrangement that optically reproduces a planar image of the light which is reflected by the photonic crystal and whose polarization has been altered, and that comprises a polarization filter for the irradiated light and the light reflected by the photonic crystal. Also, a method for measuring intraocular pressure.

An intraocular lens with an anterior ridge designed to provide a space in front of the lens optic.

The present invention generally relates to a system for two-photon or multi-photon irradiating an artificial lens, preferably an intraocular lens preferably arranged within an eye of a patient and a method for locally adjusting a polarizability and/or a refractive index of an artificial lens preferably an intraocular lens preferably arranged within an eye of a patient. The method relates in particular to fabrication of optical profiles by adjusting polarizability through two- or multi-photon processes in a non-destructive manner.

An apparatus has a central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens. The lens body has at least one haptic extending from the lens body, and the central aperture has a form of a circular hole extending fully through the lens body when the apparatus is implanted in the eye. The lens body is formed from a substantially transparent material and the central aperture includes a darkened perimeter. The darkened perimeter of the central aperture includes a darkened internal wall extending through the lens body from an anterior surface to a posterior surface of the lens body.

A method is provided for use in reducing a size of halo effect in an ophthalmic lens. The method comprises: providing data indicative of a given ophthalmic lens with a first pattern providing prescribed vision improvement, processing said data indicative of the features of the first pattern and generating data indicative of a variation of at least one feature of the first pattern resulting in a second pattern which maintains said prescribed vision improvement and reduces a size of halo effect as compared to that of the lens with the first pattern.

Intraocular implants and methods of forming intraocular implants are described herein. The intraocular implant can include a powered optic and a lens holder. The optic can be mechanically coupled to an inner periphery of the lens holder to form the intraocular implant. A portion of the lens holder can include a mask disposed about the optic to increase depth of focus in a human patient.

An accommodation-facilitating intraocular implant has: a ring sized to fit within a capsular lens bag of an eye; and a plurality of haptics angularly spaced around and radially extended from the ring. A multi-curve implantable accommodating intraocular lens has a convex anterior and concave posterior.

Exemplary light control devices and methods provide a regional variation of visual information and sampling (“V-VIS”) of an ocular field of view that improves or stabilizes vision, ameliorates a visual symptom, reduces the rate of vision loss, or reduces the progression of an ophthalmic or neurologic condition, disease, injury or disorder. The V-VIS devices and methods generate a moving aperture effect anterior to a retina that samples and delivers to the retina environmental light from an ocular field of view at a sampling rate between 50 hertz and 50 kilohertz. Certain of these V-VIS devices and methods may be combined with augmented or virtual reality, vision measurement, vision monitoring, or other therapies including, but not limited to, pharmacological, gene, retinal replacement and stem cell therapies.

A lens for use in an intraocular lens system for treating age-related macular degeneration (AMD), the lens including an anterior surface, a posterior surface, and a plurality of haptics configured to align the anterior light-converging intraocular lens with an optical axis of the eye. The plurality of haptics may have a symmetrical design and comprising ciliary-sulcus-engaging surfaces configure to position the lens within in a ciliary sulcus of an eye. At least one of the anterior surface and the posterior surface may be rendered as aspherical surfaces selected to induce spherical aberration while minimizing optical aberration and thereby provide for a continuum of retinal images to be focused at an area macula of a retina of the eye between two retinal eccentricities.

A method improves depth of focus in a first eye only by adding a higher order aberration (HOA) to the first eye by adding a monofocal optical device to the first eye. The method may also correct a spherical aberration in a second eye by inserting a monofocal aspheric IOL. The HOA added to the first eye may be selected from the group consisting of spherical, trefoil and coma. Additionally, the monofocal optical device inserted into the first eye may comprise a monofocal aspheric IOL that adds spherical aberration to the first eye. The optical device inserted into the first eye may comprise a 20 D monofocal aspheric IOL that adds 0.4 μm of spherical aberration to the first eye at 6 mm entrance pupil and adds 0.1 μm of spherical aberration to the first eye at 4 mm entrance pupil.
