Innovation Solution
A navigation apparatus that uses a detection device with a small aperture to analyze the inner structure of the eye and a processing device to apply targeted laser modifications, such as cutting patterns and bubble fields, based on calculated target coordinates to enhance the flexibility and accommodative ability of the eye lens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If simple cutting geometries are used to increase lens flexibility, then the lens can be better deformed by the capsular bag or ciliary muscle, but the individual geometry and inner structure of the eye lens are not taken into account, leading to excessive therapeutic measures and potential tissue damage
Solution Approach 1:
The patent applies local quality by adapting the cutting geometry to the specific local conditions of each patient's lens. The detection device analyzes the individual geometry and inner structure of the eye lens, and the controller uses this information to calculate customized cutting patterns that match the specific anatomical features, ensuring that cuts are made only where needed to achieve flexibility without causing unnecessary tissue damage
Solution Approach 2:
The patent implements preliminary action by performing detailed detection and analysis of the eye lens geometry and inner structure before executing any cutting therapy. The detection device captures images and data about the lens characteristics in advance, allowing the controller to plan and calculate the optimal cutting geometry tailored to each patient's specific anatomy before the actual therapeutic intervention
2Manufacturing precision
If detailed detection and analysis of eye lens structure is performed before treatment, then individualized therapy planning can be achieved, but the device complexity and measurement requirements increase
Solution Approach 1:
The patent applies universality by designing a detection device that can perform multiple functions: capturing images of the eye lens, analyzing geometric data, identifying inner structures, and providing this information to the controller for therapy planning. This multi-functional approach consolidates what could be separate complex systems into a single integrated device, reducing overall system complexity while maintaining high measurement precision
Solution Approach 2:
The patent uses an intermediary approach by introducing a controller that acts as a mediator between the detection device and the cutting therapy execution. The controller receives detailed geometric data from the detection device, processes this information to calculate customized cutting patterns, and then guides the cutting device. This intermediary layer simplifies the interface between detection and treatment while enabling precise individualized therapy planning
