To provide an intraocular lens to which a mark for assisting more accurate fixation in an eye has been applied. Provided is an intraocular lens including an optical part having a mark that is detectable under illumination of a specific wavelength range outside a wavelength range of visible light, and a support part that supports the optical part, in which the mark is indicated by a geometric pattern that allows for identification of an optical center position of the optical part and information regarding posture of the optical part in an eye.

Intraocular lenses for reducing the risk of posterior capsule opacification (PCO) are described herein. PCO can be reduced with an IOL design that increases the pressure at the posterior capsular bend, for example, by including a sharper edge design, an enlarged optical zone, and/or an increased vault height. An example ophthalmic lens can include an optic (200) including an anterior surface (202) defining an anterior side of the optic, a posterior surface (204) defining a posterior side of the optic, and an edge (210) arranged between the anterior and posterior surfaces. The edge and the posterior surface can form an angle, where the angle is less than about 90 degrees. Additionally, the ophthalmic lens can have an increased vault height. At least one of the angle or the increased vault height be configured to increase pressure on a capsular bend in a subject's eye.

A composite light adjustable intraocular lens comprises an acrylic diffractive intraocular lens, having a diffractive structure and haptics; and a silicone light adjustable lens, attached to the acrylic diffractive intraocular lens. The diffractive structure produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision, wherein the constructive interference produces a near focal point, a distance focal point corresponding to the base power of the ophthalmic lens, and an intermediate focal point between the near focal point and the distance focal point and wherein a diffraction efficiency of at least one of the diffractive orders is suppressed to less than ten percent.

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.

An apparatus has 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.

An intraocular lens system comprising at least one intraocular lens having an anterior surface and a posterior surface, wherein at least one surface of the lens is aspherical to provide for a continuum of retinal images to be focused at the retina in an area between two retinal eccentricities. The system may include an anterior light-converging intraocular lens 16 for positioning within the eye, the anterior lens having an anterior surface and a posterior surface; and a posterior light-diverging intraocular lens 17 for positioning within the eye posterior to the anterior lens, the posterior lens having an anterior surface and a posterior surface; wherein one or both surfaces of the anterior lens and/or one or both surfaces of the posterior lens are aspherical.

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 mask configured to be implanted in a cornea of a patient to increase the depth of focus of the patient includes an anterior surface, a posterior surface, and a plurality of holes. The anterior surface is configured to reside adjacent a first corneal layer. The posterior surface is configured to reside adjacent a second corneal layer. The plurality of holes extends at least partially between the anterior surface and the posterior surface. The holes of the plurality of holes are configured to substantially eliminate visible diffraction patterns.

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.

Methods and apparatus to improve or restore vision by causing a rebooting of the visual system of an eye with modification of visual search, sampling and stimulation away from the preferred retinal locus of fixation of an eye to enhance neural integration and perception of visual information from within the field of view are described herein. Some embodiments cause transient, reversible or repeatable redirection of environmental light away from the preferred retinal locus of fixation of an eye to multiple retinal locations that are not the preferred retinal locus of fixation. Some embodiments reduce exposure of environmental light at the preferred retinal locus of fixation of an eye for a determinable interval at a determinable rate. Some embodiments cause a defocusing of environmental light at the preferred retinal locus of fixation in an eye with a visual impairment or loss.
