CAPSULAR PROSTHESIS FOR POSTERIOR CHAMBER INTRAOCULAR LENS (IOL) FIXATION
20230181310 · 2023-06-15 ·

An intraocular lens (IOL) prosthesis is implanted through one or more corneal incisions made within a predetermined surgical axis defining a plane that intersects the optical axis as well as the visual axis of the human eye. At least two looped sutures are fed through suture apertures and sutured to the sclera of the eye by which a center aperture of the prosthesis is suspended in the plane within the posterior chamber of the eye and centered on either the optical or visual axis. The prosthesis is made of a thin sheet of flexibly resilient material (e.g. silicone, polyimide, acrylic, polypropylene), and can be rectangular, triangular or of any suitable geometric shape. The center aperture has dimensions that facilitates optic capture or reverse optic capture of commercially available IOLs and includes vertex features for resisting movement of the haptics of the captured IOLs once captured therein.

Intraocular optic assembly

An intraocular optic assembly can include a first lens, a first plurality of stanchions, a second lens, and a second plurality of stanchions. A central optic axis can extend through centers of the first and second lenses. The first plurality of stanchions can each extend a first distance between a first base end and a first distal end. The first lens can be connected with the first distal ends. The second plurality of stanchions can each extend a second distance between a second base end and a second distal end. The second lens can be connected with the second distal ends. Compression at the peripheries of the stanchions induces movement of the lenses apart from one other.

ACHROMATIC IOL WITH MULTIPLE LAYERS OF DIFFRACTIVE OPTICS

A multi-layer intraocular lens (IOL) includes a lens body, including an anterior diffractive optics layer, comprising a first biocompatible material, and a posterior diffractive optics layer, comprising a second biocompatible material that is different from the first biocompatible material. The anterior diffractive optics layer and the posterior diffractive optics layer are sealed in a peripheral non-optic portion of the lens body with a gap between the anterior diffractive optics layer and the posterior diffractive optics layer.

ACCOMMODATING INTRAOCULAR LENSES AND METHODS OF MANUFACTURING

An intraocular lens is disclosed that includes an optic body with a projection extending radially outwards from a peripheral surface of the optic body. The projection comprises a haptic contact surface facing radially outward, wherein the entire haptic contact surface is a flat surface. A haptic having a free distal end and a proximal portion is secured to the projection along the haptic contact surface, wherein the projection and the proximal portion interface at a butt joint without the haptic extending into the projection and without the projection extending into the haptic. The haptic also includes a haptic fluid chamber.

ACCOMMODATING INTRAOCULAR LENS SYSTEMS AND INTRAOCULAR LENS FOCUSERS
20170312070 · 2017-11-02 ·

An intraocular lens focuser (114) to be implanted in a human eye includes a resiliently deformable force applicator (140) to apply a focussing force to an accommodating intraocular lens and an attaching portion configured to enable attachment of the lens focuser in the eye. The force applicator is configured such that, in use, when a ciliary muscle of the eye is relaxed to place the accommodating intraocular lens in a distance vision condition, the force applicator is in a deformed condition and when the ciliary muscle contracts to place the accommodating intraocular lens in a near vision condition the force applicator resiles towards a relaxed non-deformed condition to at least assist in placing the accommodating intraocular lens in the near vision condition. The attaching portion has a plurality of members configured to permit attachment of the force applicator to at least one of i) an exterior of a capsular sac of the eye ii) zonules of the eye and iii) the ciliary muscle with the force applicator disposed exteriorly of the capsular sac.

VARIABLE STRENGTH INTRAOCULAR LENS AND METHOD OF USING SAME
20170312071 · 2017-11-02 ·

The present disclosure provides intraocular artificial lenses having a variable optical strength and methods of treating an eye disorder, such as presbyopia, using same. In some embodiments, the intraocular artificial lens comprises two optical elements that are moveable along the optical axis in relation to each other, for example in response to the accommodative process of the eye.

Accommodating intraocular lenses

An accommodating intraocular lens including an optic portion comprising an anterior surface and a posterior surface, a peripheral portion disposed radially relative to the optic portion and in communication with the optic portion and, the peripheral portion having a proximal portion secured to the optic portion and a free distal portion disposed away from the proximal portion, and a radially innermost surface of the peripheral portion, from the proximal portion to the free distal portion, follows a curved radially-outermost peripheral surface of the optic portion.

OPHTHALMIC DEVICES, SYSTEM AND METHODS THAT IMPROVE PERIPHERAL VISION
20170296330 · 2017-10-19 ·

The present disclosure relates to devices, systems, and methods for improving or optimizing peripheral vision. In particular, various IOL designs, as well as IOL implantation locations, are disclosed which improve or optimize peripheral vision.

TWO-PART ACCOMMODATING INTRAOCULAR LENS DEVICE
20220047383 · 2022-02-17 ·

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.
