Publication number: 20250073019Abstract: A medicament reservoir for an intraocular lens has a medicament, a through-hole, a first medicament reservoir clearance which communicates with the through-hole, a first web which delimits the first medicament reservoir clearance, a first end face which delimits the through-hole, and a second end face which is disposed so as to face away from the first end face and to delimit the through-hole. The through-hole in a region of the first end face has a first longitudinal end and in a region of the second end face has a second longitudinal end. The medicament reservoir has a displacement direction oriented from the first longitudinal end to the second longitudinal end. The first medicament reservoir clearance is formed such that the through-hole is accessible from outside the medicament reservoir via the first medicament reservoir clearance in a medicament reservoir radial direction in terms of the displacement direction.Type: ApplicationFiled: November 14, 2024Publication date: March 6, 2025Inventors: Niklas Damm, André Wolfstein

Patent number: 12193930Abstract: 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°.Type: GrantFiled: March 9, 2023Date of Patent: January 14, 2025Assignee: Carl Zeiss Meditec AGInventors: Benjamin Schreiber, André Wolfstein, Uwe Wolf, Jan Buchheister, Sergio Luque

Patent number: 12151869Abstract: 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.Type: GrantFiled: November 30, 2023Date of Patent: November 26, 2024Assignee: Carl Zeiss Meditec AGInventors: Marco Müller, Andre Wolfstein

Publication number: 20230414316Abstract: 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.Type: ApplicationFiled: November 10, 2021Publication date: December 28, 2023Inventors: Mario Gerlach, Benjamin Schreiber, Jennifer-Magdalena Masch, Thorben Badur, Andre Wolfstein
