MULTICOMPONENT INTRAOCULAR LENS
20170296331 · 2017-10-19 ·

A multicomponent intraocular lens implantable in an optical system of a human eye, comprising: a base component and a front component, the front component comprising an attachment tab which extends from a circumferential side of the optical portion of the front component and engages the flange for attaching the front component to the base component, wherein the attachment tab of the front component comprises a resilient projection that protrudes away from the optical portion beyond the flange, wherein a portion of the resilient projection is located at a non-overlapping position with respect to the haptic of the base component in a circumferential direction around the optical portions, wherein the portion of the resilient projection has a back surface which is located backwards from a front surface of the haptic of the base component in the thickness direction of the base component.

Back loaded IOL insertion cartridge

A rear-loaded injector cartridge for an intraocular lens (IOL) having a proximal opening that provides a haptic slot. The haptic slot receives a leading haptic of an IOL loaded therein, and temporarily retains the leading haptic while the optic of the IOL is inserted into a holding area of the cartridge. As the optic passes by, the leading haptic folds over the top of the optic, on its anterior side. The length of the haptic retention slot is sufficient to maintain the leading haptic in its anteriorly folded position while the IOL remains in holding area, typically while the cartridge is mated with a handpiece of the injector. The cartridge also has a rear or proximal cut out which advantageously keys with a similarly-sized rail on the handpiece so that the cartridge cannot be inserted in the wrong way.

Intraocular manipulator and related methods

In accordance with various embodiments, an intraocular manipulator is disclosed which uses negative pressure to grasp and/or manipulate an intraocular object, for example, an IOL, a crystalline lens, or an intraocular foreign body. The device comprises a tip, a stem, and a suction source. The device may be a handheld device with the negative pressure controlled by a foot pedal. Similarly, the device may be used in conjunction with other intraocular devices.

INTRAOCULAR LENS EXCHANGER
20220031450 · 2022-02-03 ·

Provided is an intraocular lens exchanger for moving a foldable intraocular lens (IOL), the intraocular lens exchanger including: an outer tube having a first passage formed in a forward/rearward direction; an inner tube disposed to be movable along the first passage and having a second passage formed in the forward/rearward direction; and a variable tube extending from a front end of the inner tube to form a variable passage connected to the second passage, in which the variable tube has an extension part having a width that increases forward in an unconstrained state in which the variable tube is not positioned in the first passage, and the extension part is provided to be elastically deformed when the unconstrained state changes to a constrained state in which at least a part of the extension part is received in the first passage.

Apparatus for the treatment of cataract
09763773 · 2017-09-19 · ·

An apparatus to treat a cataract where the cataractous lens is pierced and the resulting opening is mechanically maintained using a lens system device such as a cylindrical lens, tubular lens, pinhole device, a stent or similar small diameter device, or where the device itself is the lens. The resulting passageway for visible light created in the cataractous lens allows light to better reach the retina, thus improving vision. This lens system device that can be placed into an in situ cataract provides for a much simpler surgical technique and reduces related pre and post operative procedures and potential complications. Intraocular lenses may also be used in concert with this invention. The apparatus and related methods can be applied to humans as well as animals.

FORCEPS

The present disclosure describes a three-pronged forceps. The forceps are particularly useful for removing an intraocular lens from an eye.

METHOD FOR CONTROLLING PLACEMENT OF INTRAOCULAR IMPLANTS
20210369447 · 2021-12-02 ·

Some embodiments disclosed herein relate to devices and methods for controlling placement of intraocular implants within a patient's eye including but not limited to placement within or near the collector ducts of Schlemm's canal located behind the trabecular meshwork. In some embodiments, a handheld peristaltic rotor device having a compression element can be positioned on a corneal surface of the eye and rotated to create a peristaltic movement of blood in one or more episcleral veins to generate blood reflux within Schlemm's canal such that one or more collector ducts, or channels, of Schlemm's canal can be located. In some embodiments, an implant can be implanted near the identified location of the one or more collector ducts, or channels.

BERNOULLI GRIPPER FOR INTRAOCULAR AND CONTACT LENSES
20220168095 · 2022-06-02 ·

A Bernoulli gripper for ophthalmic lenses includes a gripper body with a first cavity corresponding in shape to an optic zone of an ophthalmic lens and a first channel formed within the gripper body. The first channel penetrates the first cavity at one end and includes a first port in the gripper body at another end of the first channel. The first channel is enabled to supply a fluid medium from the first port to the first cavity at a first velocity such that the ophthalmic lens positioned with the optic zone in proximity to the first cavity is subject to a first pressure force against the first cavity by the Bernoulli effect.

INTRAOCULAR LENS INJECTOR ASSEMBLY HAVING SHUTTLE ASSEMBLY RETAINING INTRAOCULAR LENS IN STORAGE VIAL AND OPERABLY PRESENTING INTRAOCULAR LENS IN INJECTOR ASSEMBLY

A shuttle, vial and injector are provided for storing and presenting an IOL to a patient. The shuttle includes operably engaged shuttle plates having a set of confronting surfaces that flex about a flexure interface between a storage configuration, with at least an optic of an IOL in a nominal state and a loading configuration, with at least an optic of an IOL in a deformed state. The vial engages the shuttle and maintains the shuttle in the storage configuration. The injector receives the shuttle from the vial and includes surfaces for flexing the portions of the shuttle plates to the loading configuration upon engagement with the injector, wherein the shuttle plates impart a predetermined curvature to at least a portion of the IOL.

SUCTION-BASED TOOL FOR POSITIONING INTRAOCULAR IMPLANTS

In some embodiments, a suction-based tool for positioning an intraocular implant includes a tool body defining an internal channel; a suction extension extending through the internal channel; and a suction attachment connected to an end of the suction extension. In additional embodiments, a suction-based tool for positioning an intraocular implant includes: a tool body including a tool tip; a joint at an end of the tool tip; and a suction attachment connected to the tool tip via the joint.
