Ophthalmological Implant Haptic Root Codes for Reliable Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmological implants, particularly intraocular lenses, face challenges in unambiguous identification due to the risk of mix-ups and incorrect labeling, which can lead to costly recalls and patient complications, despite existing methods like IR labeling and laser-engraved matrix codes being complex and prone to errors.
Innovation Solution
A structural code is embedded on the haptic root of the ophthalmological implant, using a machining or laser beam forming method, to provide unambiguous identification without additional materials or methods, allowing for reliable identification before and after implantation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If IR labeling with fluorescing dyes is used, then identification capability is improved, but device complexity and manufacturing cost increase due to additional materials and complex detection systems
Solution Approach 1:
The patent extracts the identification function from complex external labeling systems (IR labels, fluorescent dyes, matrix codes) and integrates it directly into the haptic root structure through a simplified structural code that can be read by standard optical characterization systems, eliminating the need for specialized detection equipment and additional materials
Solution Approach 2:
Instead of using physical labels or codes that require separate application processes, the patent creates a structural code that is an inherent geometric feature of the haptic root itself, copied directly from the manufacturing process, thereby eliminating separate labeling steps and reducing complexity
2Reliability
If laser-engraved matrix codes are applied, then identification reliability is improved, but manufacturing complexity increases due to additional production steps and separate apparatuses
Solution Approach 1:
The patent merges the identification code creation with the haptic root manufacturing process itself, so that the structural code is formed simultaneously with the functional component rather than being added as a separate post-processing step, thereby eliminating the need for separate laser engraving apparatus and reducing manufacturing complexity
Solution Approach 2:
The structural code is prepared and integrated into the haptic root design before the final manufacturing step, ensuring that identification capability is built-in from the outset rather than requiring additional verification or correction steps later in the process
3Loss of information
If separate labeling methods are used, then identification capability is improved, but risk of mix-up increases due to multiple production steps and separate apparatuses
Solution Approach 1:
By combining the structural code formation with the haptic root manufacturing in a single integrated process, the patent eliminates intermediate handling and transfer steps where mix-ups could occur, ensuring that each implant's identification code is permanently and correctly associated with its functional components from the moment of creation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures simple, reliable, and error-free identification of the implant by integrating the structural code during the forming process, reducing the risk of mix-ups and enabling accurate tracking throughout the production and implantation process.
Implementation Method 1
the ophthalmological implant is formed by application of a machining lathing (and/or milling) method, a laser beam forming method or a primary forming method

AI summary
An ophthalmological implant including an imaging optical element, and a haptic with a haptic root. Also, a corresponding method for producing an ophthalmological implant and a characterization system for identifying an ophthalmological implant for example an intraocular lens. The implant includes an unambiguous label and hence an unambiguous and reliable identification option. The label is not able to be mixed-up and is possible with minimal additional technical outlay. The implant includes a rotationally symmetric structural code of identification data of the ophthalmological implant arranged on the haptic root and/or the region of the haptic proximate the haptic root. Also, a method for producing an ophthalmological implant, in which the implant receives, directly during or after the forming, a rotationally symmetric structural code of identification data.
