Ophthalmic device for drug delivery

An ophthalmic implant for drug delivery. The implant includes a primary intracapsular device coupled to a secondary device, wherein, when implanted in a patient's eye, the primary intracapsular device is held in place by the patient's capsular bag and the secondary device is held in place by the primary intracapsular device. The implant may be inserted in the eye by injecting the primary intracapsular device into the eye either before or after attaching the secondary device to the primary intracapsular device, and subsequently positioning the joined secondary device and primary intracapsular device with the primary intracapsular device held in place by the patient's capsular bag and the secondary device held in place by the primary intracapsular device. The secondary device may be designed to hold a tertiary device that can be implanted and attached at the time of surgery or anytime postoperatively.

IMPLANTABLE ACCOMMODATING INTRAOCULAR LENSES AND RELATED METHODS
20220079745 · 2022-03-17 ·

An implantable accommodating intraocular lens (IOL) has an optic lens sized to fit within a capsular lens bag of an eye; and a plurality of haptics angularly spaced around and radially extended from the optic lens, with each haptic: having a tongue that forms an arcuate sulcus gripping part that, in use within the capsular lens bag, inserts into and follows a circumferential groove of the sulcus to restrict circumferential sliding of the tongue around the sulcus; and being structured to move, under contraction and expansion of ciliary muscles of the eye, to adjust the optic lens to accommodate a focal power of the eye.

Aspherical Multifocal Intraocular Lens

A multifocal intraocular lens has an anterior lens surface which includes a first optic of a first radius and a second optic of a different radius. The posterior surface of the lens include an aspheric surface.

STABLE IOL BASE DESIGN TO SUPPORT SECOND OPTIC
20210322150 · 2021-10-21 ·

An intraocular lens (IOL) configured to support a first optic for functioning as a single lens IOL and configured to support a second optic for functioning as a dual optic IOL. The base includes a first optic for providing a base power. A recess in an anterior rim of the base is configured for positioning a radial extension of a second optic. The geometry of the recess is configured to securely couple to the radial extension to prevent rotation of the second optic relative to the base and prevent tilting of the second optic relative to an optic axis.

Intraocular lens

An intraocular lens comprising a lens optic coupled to at least one haptic and at least one deformable connecting bar positioned between the lens optic and the at least one haptic.

HYBRID ACCOMMODATING INTRAOCULAR LENS ASSEMBLAGES INCLUDING DISCRETE LENS UNIT WITH SEGMENTED LENS HAPTICS
20210307898 · 2021-10-07 ·

Hybrid Accommodating Intra Ocular Lens (AIOL) assemblages including two discrete component parts in the form of a discrete base member for initial implantation in a vacated capsular bag and a discrete lens unit for subsequent implantation in the vacated capsular bag for anchoring to the discrete base member. The lens unit includes a lens optics having at least two segmented lens haptics radially outwardly extending therefrom.

INTRAOCULAR LENS DESIGNS FOR IMPROVED STABILITY

Intraocular lenses (IOLs) that improve lens stability by, for example, increasing anterior-posterior stiffness of the IOL, increasing anterior-posterior dimensions of the IOL and/or increasing contact area with the equator of the bag to resist movement of the IOL as the bag collapses over time. These IOLs may be non-modular (single component) or modular (multiple component). In modular embodiments, the IOL system may include intraocular base and optic components, which, when combined, form a modular IOL.

DEVICES TO SUPPORT AND POSITION AN INTRAOCULAR LENS WITHIN THE EYE AND METHODS OF USE

An implantable device for supporting an intraocular lens in an eye including a lens support structure having a central aperture; and one or more fixation arms coupled to the lens support structure and configured to locate and stabilize the device within the eye. Related tools, systems, and methods are provided.

A multifocal intraocular lens has an anterior lens surface which includes a first optic of a first radius and a second optic of a different radius. The posterior surface of the lens include an aspheric surface.

EXCHANGEABLE LENS PLATFORM
20210244531 · 2021-08-12 ·

An exchangeable lens platform (ELP) comprises a horseshoe-shaped ring structure, which has a memory strip incorporated therein, into which the haptic end components of the intraocular lens (IOL) can engage diametrically opposite portions of the ring structure. In this manner, the exchangeable lens platform (ELP) can not only be opened or expanded so as to be disposed within any sized capsular bag in a secure and stabilized manner, but diametrically opposite portions of the exchangeable lens platform (ELP) can effectively fold upon themselves such that the exchangeable lens platform (ELP) will effectively be partially folded in half such that the diametrically opposite folded portions of the exchangeable lens platform (ELP) can effectively engage diametrically opposed internal wall portions of the fornix of the capsular bag so as to permit the intraocular lens (IOL) to then be properly centered, oriented, stabilized, and secured within the eye. In addition, since the haptic components of the intraocular lens (IOL) are disposed upon the exchangeable lens platform (ELP) and do not engage internal peripheral wall portions of the capsular bag, the intraocular lens (IOL) can be removed and replaced with another intraocular lens (IOL).
