  • Publication number: 20240109711
    Abstract: A container has an ophthalmic injector holding an intraocular lens and a first vessel at least partially filled with a fluid. The intraocular lens is surrounded by the fluid and the first vessel is provided with a lid which closes the first vessel in a fluid-tight manner and which is releasably connected to the first vessel. A second vessel is coupled to the first vessel. A fluid-tight closure is provided between the first vessel and the second vessel, wherein the lid is coupled to the closure by a coupler, and, when the lid is released from the first vessel, the closure is configured, via the coupler, to pass from a closed position to an open position, such that the fluid can flow from the first vessel into the second vessel.

  • Publication number: 20230414316
    Abstract: The invention relates to an ophthalmological implant (100) with an optically imaging element (110), a digital product identifier (130) being arranged on the optically imaging element. The invention additionally relates to a corresponding method for producing the implant and to a machine reading system (200) for detecting and decoding the digital product identifier. The aim of the invention is to provide an ophthalmological implant and a method for producing same, said method allowing a unique and complete product identifier and a check thereof using simple means at any point in time. This is achieved by an ophthalmological implant with a digital product identifier (130) which is implemented by means of an encoded point grid (135) of identifier points (57), said point grid being machine-readable in the visible light range and having one irregular semi-random character.

  • Publication number: 20230218796
    Abstract: The disclosure relates to a tissue adhesive for use in a treatment method in which an ophthalmological implant is implanted in a human or animal patient and the ophthalmological implant is connected, at least partially in an integrally bonded manner, to eye tissue of the patient via the tissue adhesive. The disclosure also relates to an ophthalmological implantation system including an ophthalmological implant for implantation in a human or animal eye and to a tissue adhesive via which the ophthalmological implant is connectable, at least partially in an integrally bonded manner, to eye tissue of the patient.

  • Publication number: 20230210656
    Abstract: An accommodative intraocular lens includes a first lens part, a haptic, and a flexible membrane. The flexible membrane is arranged adjacent to a distal optical body surface, delimits a cavity together with the distal optical body surface and is transparent to light. A second lens part has a hollow cylinder coupled releasably to the first lens part, as a result of which the intraocular lens can be brought into a coupling state in which the second lens part is arranged on a distal side of the first lens part and the hollow cylinder is configured to deform the membrane by a longitudinal displacement of the hollow cylinder parallel to the optical axis. The hollow cylinder has on its exterior an outer face and a bearing face arranged adjacent to a proximal end of the outer face and encloses, with the outer face, an angle of less than 180°.

  • Publication number: 20210236269
    Abstract: The disclosure relates to an ophthalmological instrument with a main body and at least one ligand (L) immobilized on the main body. In the implanted state of the ophthalmological implant, the ligand (L) binds and/or deactivates at least one fibrinogen and/or cytokine. The disclosure further relates to a method for producing an ophthalmological implant, and to a use of a ligand (L), via which at least one fibrinogen and/or cytokine is to be bound and/or deactivated in the implanted state of the ophthalmological implant, for producing an ophthalmological implant.
