Problems solved by technology

All hitherto known methods must be integrated into the manufacturing chain in such a way that it is not possible to wrongly identify intraocular lenses due to operating or programming errors
Since here in each case additional manufacturing steps are processed in separate methods and with separate devices, there is still a residual risk of confusion

Embodiment Construction

[0067] Figure 1a is a first embodiment of an ophthalmic implant 1 with a structured code 5 according to the invention. The ophthalmic implant 1 is an intraocular lens comprising a central optical lens 2 representing the optical imaging element of the ophthalmic implant 1 and a haptic 3 having a haptic root 4 along the annular edge 2R of the central optical lens 2 The subregions of are connected to the central optical lens 2 and here partially surround the central optical lens from both sides. A structured code 5 of identification data of the ophthalmic implant 1 is arranged at the haptic root 4 of the intraocular lens and at the region of the haptic device 3 close to the haptic root 4 . Here, in this case, the structured code 5 of the type and refractive power of the intraocular lens. In this case, the structured code 5 is used in the form of a barcode system, ie arranged rotationally symmetrically around the central optical lens 2 on the haptic root 4 and on the haptic devi...

Abstract

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.

Description

technical field [0001] The invention relates to an ophthalmic implant comprising an optical imaging element, in particular a central optical lens, and a haptic with a haptic root connected to the optical imaging element. In particular, such ophthalmic components are intraocular lenses. The invention also relates to a corresponding method for producing an ophthalmic implant, wherein the ophthalmic implant is shaped by means of machining turning, in particular by means of laser shaping or prototyping. Furthermore, the invention relates to a characterization system, a computer program product and a computer-readable medium for identifying ophthalmic implants, in particular intraocular lenses. Background technique [0002] Most ophthalmic implants, especially those made of artificial materials, most involving commercial intraocular lenses (IOLs), are identified by means of labels on the primary and secondary packaging. In addition to manufacturer information, one finds, for ex...
