Ophthalmic device having opaque and decentered light-transmissive portions for alleviating symptoms relating to ocular diseases
Embodiments concern an intraocular implantable device operable comprising a disk-shaped body having a symmetry axis and which further comprises a light-transmissive portion and an opaque portion wherein the light-transmissive portion is decentered with respect to the symmetry axis.
INTRAOCULAR LENS DEVICE AND RELATED METHODS
An intraocular device that includes a bas member is provided. The device can be an accommodation intraocular lens device with the base member and a power changing lens. The base member comprises an annular haptic that surrounds a central cavity having an open end. The power changing lens is configured to fit within the central cavity. The haptic comprises one or more projections, e.g., tabs that hold another device in position. In the case of the accommodating intraocular lens device, the other device is the power changing lens. The base member and the power changing lens are maintained separate until assembly in the eye of the patient. During assembly, the base member is advanced into the capsular bag of a patient through a capsulorhexis and oriented such that the open end of the central cavity faces the cornea. Subsequently, the power changing lens is advanced into the central cavity through the capsulorhexis. The one or more tabs are placed anterior of the power changing lens to secure the power changing lens within the cavity.
Optical Implant And Methods Of Implantation
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.
DUAL REGION ACCOMMODATING INTRAOCULAR LENS DEVICES, SYSTEMS, AND METHODS
Disclosed herein is an implantable accommodative IOL device for insertion into an eye of a patient, comprising an active region and a passive region. The active region has a first thickness and first refractive index, and the active region comprises an electrically responsive optical lens having variable optical power. The passive region is disposed at a periphery of the active region, and the passive region has a second thickness and a second refractive index. The second refractive index is different than the first refractive index. Thus, the light beams passing through the active and passive regions have a phase difference, thereby providing an extended depth of field.
INTRAOCULAR IMPLANT WITH REMOVABLE OPTIC
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.
POLYMERIC COMPOSITION EXHIBITING NANOGRADIENT OF REFRACTIVE INDEX
Ionized radiation-absorbed, dose sensitive, highly flexible polymeric compositions are provided that exhibits multidirectional changes in refractive index. Also provided are methods of producing a precision multi-directional nanogradient of refractive index in a polymeric composition.
MULTIFOCAL INTRAOCULAR LENS WITH EXTENDED DEPTH OF FIELD
Multifocal intraocular lens with extended depth of field that comprises, in at least one of the surfaces (2), a small zone with a multifocal profile with a defined optical axis (3) and, in the peripheral region and coaxial to the multifocal zone, a ring-shaped opaque mask (1) that partially or totally block light to produce a small aperture effect and, therefore, the multifocal profile has a radius equal or larger than the internal radius of the mask (1), and there is at least one transition between focal zones or one diffractive step inside the internal radius of the mask (1).
LENS DESIGN
An intraocular lens is configured to reduce or eliminate oblique incident light photic disturbances in the eye. The lens includes anterior and posterior surfaces defining a central lens optic extending from the anterior to the posterior surfaces and a peripheral portion outside of the central lens optic. The peripheral portion is a prismatic lens that redirects oblique incident light on the peripheral portion forward of the nasal retina in the eye and onto the ciliary body/pars plana region.
Foldable intraocular lens and method of making
A foldable intraocular lens for providing vision contains an optic body that includes an optical zone and a peripheral zone entirely surrounding the optical zone. The optic body has an anterior face, a substantially opposing posterior face, an optic edge, and an optical axis. The anterior face comprises a central face, a peripheral face, and a recessed annular face therebetween that is disposed posterior to the peripheral face. The intraocular lens further comprises at least one haptic that is integrally formed with the peripheral zone. The haptic comprises a distal posterior face, a proximal posterior face, and a step edge disposed at a boundary therebetween. The haptic further comprises a side edge disposed between the optic edge and the step edge. The proximal posterior face and the posterior face of the optic body form a continuous surface. An edge corner is formed by the intersection of the continuous surface with the optic edge, the side edge, and the step edge.
Polymeric composition exhibiting nanogradient of refractive index
Ionized radiation-absorbed, dose sensitive, highly flexible polymeric compositions are provided that exhibits multidirectional changes in refractive index. Also provided are methods of producing a precision multi-directional nanogradient of refractive index in a polymeric composition.
