Abstract:
An IOL utilizes a haptic (100) formed as a toroid portion (102) configured to fit into a capsular bag of an aphakic eye of a patient. The toroid portion may be separate from an IOL optic and may include a receiving feature (104) for the IOL optic. The toroid portion may be configured for intraoperative fluid-filling for snug fitting at the equator of the capsular bag, in order to immobilize the IOL optic.
Abstract:
Die Erfindung betrifft eine Anordnung zur Implantation in den Sulcus Ciliaris. Die Anordnung umfasst einen Grundkörper (1) mit einer Optik-Aufnahme (8) und mindestens eine Grundkörper-Haptik (13) zur stabilen Platzierung des Grundkörpers (1) in dem Suicus Ciliaris. Ferner hat die Anordnung eine Kapselsack-Intraokularlinse (2), die eine Optik (3) zur Anordnung in der Optik-Aufnahme (8) aufweist. Die Optik (3) hat eine optische Achse (4), eine anteriore Optikfläche (5), eine posteriore Optikfläche (6) und eine zwischen der anterioren Optikfläche (5) und der posterioren Optikfläche (6) verlaufende Randfläche (7). Der Grundkörper (1) und die Kapselsack- Intraokularlinse (2) stehen in zusammengesetztem Zustand der Anordnung in fester Verbindung miteinander.
Abstract:
An intraocular lens fixation device is herein disclosed, the device having an optic lens element, at least two haptics attached to the optic element, and a flexible member having a first end attached to the haptic and a second end attached to a connector member. The flexible member may be a surgical thread and the connector member may be configured for attachment to a needle.
Abstract:
The present invention concerns a method for manufacturing an intraocular ophthalmic lens intended for a patient, this method comprising the following steps: • measuring biometric data specific to the patient; • choosing a distribution of light to be obtained after correcting the patient's vision; • choosing a type of aberration to be corrected and an extent of aberration correction to be applied; • determining intrinsic parameters of the lens; • from the results of the biometric data measurements, form the type and extent of aberrations to be corrected, from the selected light distribution and from the determined parameters of the lens, calculating geometrical parameters for the lens in such a way that the set formed by the ophthalmic lens and the eye of the patient generates a light distribution specification corresponding to the chosen light distribution and to the chosen aberration corrections. The invention further concerns an ophthalmic lens obtained by said method.
Abstract:
An intraocular lens used in cataract surgery of people who have visual impairment. A lens (1) used when there is no capsule support, and comprising holder indentations (13) formed on the leg (12) part of the lens (1) and enabling fitting of the lens (1) into the eye, a tip knob structure (14) preventing sliding and falling, and rounded lens edges (15), and it is characterized in that; it comprises holder indentations and/or protrusions (13) formed in spiral structure from said tip knob structure (14) (b) to the haptic (12) bottom area (d), and a twist (16) and/or notch applied on the leg structure when required.
Abstract:
Modular IOL systems including a base (55) and a lens (65), wherein the lens includes fixed (95) and actuatable tabs (96) for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or postoperatively. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.
Abstract:
Acrylate-acrylamide copolymers are disclosed. They are rigid and glassy in dry state at room temperature (from about 23°C to about 28°C), but are soft and very deformable and have a high refractive index, a high glistening resistance and a low aging-related surface light scattering in fully hydrated state. They are particularly suitable for making wet-packed intraocular lenses (IOLs) which can be delivered through sub 2.0 mm incisions.
