An ophthalmic lens for providing enhanced vision includes a finished optic comprising a base optic and a membrane. The base optic has an anterior surface and an opposing posterior surface, at least one of the surfaces having a first value of a surface quality parameter. The base optic also includes a membrane including an inner surface and an outer surface, the inner surface covering one or more of the surfaces of the base optic. The outer surface has a second value of the surface quality parameter, wherein the second value is greater than the first value.

Ophthalmic lenses with enhanced surface and methods of fabrication thereof

An accommodating intraocular lens for providing a range of accommodative vision contains an optic and a haptic. The optic is disposed about an optical axis and includes an anterior surface and a posterior surface defining a clear aperture of the optic. The haptic is at least partially disposed inside the optic and includes an inner structure, an outer structure, and a plurality of arms disposed between and connecting the inner structure and the outer structure. The inner structure is circumferentially disposed about the optical axis, while the outer structure is circumferentially disposed about the inner structure and has an outer face. Each arm has proximal portion adjacent the inner structure and a distal portion adjacent the outer structure that is bifurcated in a radial direction from the proximal portion. The intraocular lens also has an outer surface defined by outer surfaces of the plurality of arms and an outer surface of the outer structure. The inner structure and at least a portion of the arms are disposed inside the clear aperture. The distal portion of each arm has a larger axial extent than an axial extent of the inner portion. The distal portion of each arm has a larger axial extent along the outer surface than an axial extent of the outer structure along the outer surface.

Intraocular lens and methods for providing accommodative vision

An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. Certain haptic features improve the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. Furthermore, certain aspects also provide enhanced bag-sizing capability so that the IOL better fits within the capsular bag.

Accommodating intraocular lenses

A deformable intraocular has a haptic that supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may include a cap on one or both surfaces of the lens. The lens may include a force transfer member-that couples forces from the haptic to the cap, so that a radial force on the haptic changes the curvature of the cap. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.

Intraocular lens having a haptic that includes a cap

An interbody spacer for the spine is provided. The interbody spacer includes a polymer cage and a plurality of bone screws configured to anchor the cage between two vertebrae of the spine. The cage includes a screw receiver configured to receive a metallic plate screw for attaching a plate to cover the proximal ends of the bone screws to prevent them from backing out over time with respect to the cage. The screw receiver has deflectable extensions that snap into cage to retain the screw receiver to the cage. The screw receiver also includes a transverse flanges that provide anti-rotation and alignment to the screw receiver relative to the cage and; furthermore, the screw receiver further includes a self-locking feature that increases purchase on the plate screw providing a secured cover plate for anti-backout protection for the bone screws.

Interbody spacer

An accommodating intraocular lens (aIOL) is disclosed, with an optic that changes shape in response to an ocular force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. A surface adherent improves the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. One way to enhance force transfer is to provide a surface layer of an adhesive to the haptic and/or optic, for instance a reversible bioadhesive material. Or, portions of the exterior surface of the IOL may have microfibers thereon that mimic the adhesive properties of Gecko feet. Another aspect is application of a reversible bioadhesive material to the interior of the empty capsular bag prior to introduction of an injectable polymer IOL.

Fixation of ophthalmic implants

An intraocular lens is disclosed with an optic that changes shape in response to forces exerted by the zonules of the eye. A haptic with an inner and outer ring couples the optic to the capsular bag of the eye. The haptic stresses the optic when the intraocular lens is in a natural state such that the internal stress is present throughout the accommodation range in order to prevent ripples and/or waves in the optic.

Pre-stressed haptic for accommodating intraocular lens

An intraocular lens for providing accommodative vision includes an adjustable optic and a haptic that is operably coupled to the optic. The adjustable optic comprises a central zone and an annular zone surrounding the central zone. The optic may also comprise additional annular zones. The haptic comprises a transparent portion protruding into the adjustable optic. The intraocular lens has a disaccommodative configuration in which the central zone has a base optical power and an accommodative configuration in which the central zone has an add optical power that is at least about 1 Diopter greater than the base optical power. The central zone and the annular zone have different optical powers when the adjustable intraocular lens is in the accommodative configuration and/or when the adjustable intraocular lens is in the disaccommodative configuration.

Multifocal accommodating intraocular lens

A device includes a plurality of ringlets connected together to form a ring having a longitudinal axis. Each ringlet includes a first element and a second element. The first and second elements each extend from a first end through a central portion to a second end. The first and second ends are disposed at radially outer positions with respect to the ring than the central portion. The central portion is longitudinally displaced from the first and second ends. The first and second elements are separated and spaced apart from each other at the central portions thereof and are joined together at the first ends thereof and the second ends thereof. The ringlets are connected together such that the first ends of the elements of one ringlet are connected to the second ends of the elements of an adjacent ringlet.

Intraocular lens and capsular ring

An intraocular lens for implantation in a capsular bag of an eye includes an optic disposed about an optical axis and a haptic including a protruding portion disposed inside the optic. The optic has an anterior face and an opposing posterior face that are configured to provide a lens power. In response to an ocular force of the eye, the haptic transmits a force that alters one or more of a shape of the optic and an axial thickness of the optic. The protruding portion of the haptic has a refractive index that is equal to a refraction index of the optic for at least one a wavelength within the visible spectrum.
