Accommodating intraocular lenses with toric surface

Disclosed are toric accommodating intraocular lenses. In one embodiment, a toric accommodating intraocular lens comprises an anterior element and a posterior element. The anterior element can comprise an anterior optical surface. The posterior element can comprise a posterior optical surface. A fluid-filled optic fluid chamber can be defined in between the anterior element and the posterior element. The toric accommodating intraocular lens can be configured to correct for corneal astigmatism, spherical aberration, or a combination thereof.

ACCOMMODATING INTRAOCULAR LENSES

Accommodating intraocular lenses including an optic having an anterior element and a posterior element defining an optic fluid chamber, wherein the optic is aspheric across all powers throughout accommodation or disaccommodation. Intraocular lenses, optionally accommodating, where an optic portion is centered with a midline of a height of the peripheral portion, the height measured in the anterior to posterior direction.

Sulcus implants and methods of using the same

This disclosure provides ophthalmic implants such as sulcus implants which can comprise one or more drug delivery devices. Further provided herein are methods of using the drug delivery ophthalmic devices described herein for implantation into a subject's eye, e.g., into an eye's ciliary sulcus or capsular bag.

ACCOMMODATING INTRAOCULAR LENS

Disclosed is an accommodating intraocular lens device for treatment of an eye including a stabilization haptic (120) configured to be positioned within a region of an eye and a lens body having a sealed chamber containing a fixed volume of optical fluid. The lens body includes a shape changing membrane (145) configured to outwardly bow in a region surrounding the optical axis of the eye; a shape deformation membrane configured to undergo displacement relative to the first shape changing membrane; and a static element (150). An inner surface of the shape changing membrane, an inner surface of the shape deformation membrane and an inner surface of the static element collectively form the sealed chamber. The lens device also includes a force translation arm (115) having a first end configured to contact an outer surface of the shape deformation membrane of the lens body and a second end configured to engage a ciliary structure of the eye. The force translation arm is configured to move relative to the lens body upon movement of the ciliary structure.

Two-part accommodating intraocular lens device

A two-part accommodating intraocular lens (IOL) device for implantation in a capsular bag of a patient's eye. The IOL device includes a primary lens assembly and a power changing lens. The primary lens assembly includes a fixed lens and a peripherally disposed centration member. The centration member has a circumferential distal edge and a first coupling surface adjacent the circumferential distal edge. The power changing lens has an enclosed, fluid- or gel-filled lens cavity and haptic system disposed peripherally of the lens cavity. The haptic system has a peripheral engaging edge configured to contact the capsular bag and a second coupling surface. The first and second coupling surfaces are in sliding contact with one another to permit movement of the power changing lens relative to the primary lens assembly and also to maintain a spaced relationship between the fixed lens and the lens cavity during radial compression of the power changing lens.

An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with fold(s) extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes. A third lens component coupled to the first or second component provides additional optical power.

Accommodative Intraocular Lens Combination with Independent Fixed and Variable Power Lens Sections

The accommodative intraocular lens combination includes mechanically and optically independent lens sections including a static, fixed power lens section to restore refraction of the eye and an, independent, dynamic, variable power lens section to restore accommodation of the eye. The preferred embodiment is a combination of a fixed power lens section, for example, a monofocal intraocular lens implanted inside the capsular bag in combination with a variable power lens section implanted at the sulcus plane and driven by the ciliary mass directly. The lens can include optics comprising free-form surfaces according to orders which exceed third order Zernike and can include additional corrective optics to modulate fixed and variable residual optical.
