10258463 · 2019-04-16 · ·

A novel phakic intraocular lens implantation without viscoelastics and an instrument thereof. The special designed instrument is employed to achieve a purpose of maintaining an anterior chamber only with a perfusion liquid in the surgery, so as to get rid of the influence of the viscoelastics completely. The viscoelastics are not used, so that there is no need to inject the viscoelastics or remove the viscoelastics as in traditional methods, the surgery time is shortened such that total time of surgical procedures from incision construction to incision hydration can be reduced to only 13 minutes, and viscoelastic-related complications, such as postoperative high intraocular pressure and lens opacity, are completely avoided.

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.

VISCOELASTIC APPLICATOR FOR IOL INSERTION APPARATUS
20190083309 · 2019-03-21 ·

A system for preparing an intraocular lens (IOL) injector for receipt of an IOL. A manifold mates with an injector cartridge and easily distributes a lubricating agent to a load chamber of the cartridge. The IOL is then transferred into the load chamber. The cartridge may be rotatably coupled to the handpiece, and then converted from a preparation and load position to a delivery position. The manifold may remain external to the load chamber or fit within the load chamber and include a handle that remains outside. One or more internal channels in the manifold lead from one or more inlet ports to surfaces in the load chamber than contact the IOL.

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.

Preloaded injector with rotatable member for storing and injecting hydrophobic intra ocular lenses

A preloaded injector for storing and injecting hydrophobic intra ocular lenses (IOL) comprises a plunger (2), an injector body (12), an adapter (16), a rotatable member (18), a cartridge (20) with a nozzle tube (22) and a stopper (26). The rotatable member (18) is provided around the cartridge (20) for setting the cartridge (20) from an open position to a closed position. The rotatable member (18) is furnished with a portion interfering with a portion of the stopper (26) keeping the stopper (26) irremovable in its first position but releasing the stopper (26) in its second position.

Devices to support and position an intraocular lens within the eye and methods of use
12036109 · 2024-07-16 · ·

A device for supporting an intraocular lens in an eye. The device has a lens support structure having an inner perimeter surface defining, at least in part, a central opening. When implanted, light may pass through the central opening towards the retina. The device has at least three fixation arms, each having an origin portion coupled to the lens support structure and a terminal portion comprising an anchor for trans-scleral fixation of the device. Prior to implantation, at least one fixation arm is biased towards a folded configuration and has a bend between the origin portion and the terminal portion. The origin portion extends away from the lens support structure and the anchor of the terminal portion is positioned over or under at least one of a portion of the lens support structure and a portion of the central opening. Related tools, systems, and methods are provided.

Apparatus for guiding surgical formation of a pair of symmetrical sclerectomies in an eye of a patient, including a multi-diameter generally circular cutout portion including at least a first and second portions having corresponding first and second diameters, the cutout portion being arranged for placement over the limbus of the eye and for centering the limbus within one of the first and second portions, thereby enabling estimating the diameter of the limbus, and at least first and second series of sclerectomy guiding apertures formed about the cutout portion, each guiding aperture of the first series having a paired guiding aperture in the second series formed 180 thereapart relative to a center of the cutout portion, the at least first and second series of sclerectomy guiding apertures together including at least one pair of guiding apertures having a diameter therebetween which is wider than at least one of the first and second portions.

Modular intraocular lens designs, tools and methods

Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.

INTRAOCULAR LENSES (IOLs) AND RELATED ASSEMBLIES AND INTRAOCULAR ATTACHMENT METHODS
20190000610 · 2019-01-03 ·

Intraocular lenses and related assemblies and intraocular attachment methods are disclosed herein. In one embodiment, an intraocular lens assembly comprises a helical-shaped coil fastener to affix an intraocular lens to an iris to correct for astigmatism, presbyopia, and/or myopia or hyperopia. The helical-shaped coil fastener comprises a head and a helical wire extending from a bottom surface of the head and comprising a pointed tip opposite the head. The helical-shaped coil fastener is configured to be affixed to the iris by rotatable penetration of the iris, and thus can be removed from the iris by reverse rotation of the helical-shaped coil fastener. The helical-shaped coil fastener has a low volume, large surface area, low cross-sectional area of penetration, and an oblique angle of penetration. Thus, the helical-shaped coil fastener is easy to apply, easy to remove, minimizes tissue damage, maximizes stability, and minimizes penetration force.
