A method for calculating the required cylindrical power of a toric implant by using both the measured pre-operative corneal / ocular astigmatism and the predicted surgically-induced astigmatism. The post-operative corneal / ocular astigmatism is predicted using power vector analysis of the surgical technique employed by the surgeon. Such a method provides a more accurate method of calculating the required spherocylindrical refractive power of the implant. The method can be implemented manually, but preferably is automated by implementation on a computer through appropriate software.

The invention relates to an ophthalmological implant (1), which comprises an optically imaging element (2) and a haptic element (3), which has a haptic element root (4). The present invention also relates to a corresponding method for producing an ophthalmological implant and to a characterization system (10) for identifying an ophthalmological implant, in particular an intraocular lens. The problem addressed by the invention is that of providing a unique identification on the ophthalmological implant and thus providing a possibility for unique and reliable identification. It should be possible to apply the identification with positive guidance, without the possibility of mix-ups and with minimal additional technical complexity. This problem is solved in that a rotationally symmetrical structural coding (5) of identification data of the ophthalmological implant is arranged on the haptic element root and / or the region of the haptic element near the haptic element root. The problem is also solved by means of a method for producing an ophthalmological implant, in which method, directly during or after the forming of the ophthalmological implant, the ophthalmological implant receives a rotationally symmetrical structural coding (5) of identification data by means of the same method.

The present invention relates to a composition for ophthalmological products, to corresponding copolymers and the preparation thereof and to the use thereof for the production of ophthalmic lenses or ophthalmological implants and to these products.

The present invention describes implantable therapeutic devices, systems and methods for treating patients. The device comprises a hollow refillable housing (130) for implantation in the posterior segment of the eye through a puncture in the sclera of the eye, comprising a proximal retaining structure (120) protruding outwardly from a proximal region of the housing, an access portion An opening, and a pierceable barrier (140) positioned at least partially within the passage portion opening, the pierceable barrier being configured to be repeatedly pierced. The rigid porous structure (150) is positioned in a region of the housing away from the passage portion opening into a reservoir (160) extending along an axis between the pierceable barrier and the porous structure, the reservoir comprising dimensions A volume determined to deliver a therapeutic amount of a therapeutic agent to the eye over an extended period of time. A cover (110) is coupled to at least an upper surface of the proximal retention structure.
