Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified deep learning model is used to analyze all eye images regardless of photo mode, then the system complexity is reduced, but the analysis accuracy decreases significantly
Solution Approach 1:
The patent segments the eye image analysis task by dividing it into different photo modes (mydriatic/small pupil, slit light/diffused light) and assigns a dedicated deep learning model to each mode. This segmentation allows each model to be optimized for its specific photo mode, thereby maintaining low system complexity while achieving high analysis accuracy for each category.
2Measurement precision
If existing AI systems are limited to specific eye image types captured in specified modes, then the analysis accuracy is improved, but the adaptability and coverage of the system deteriorates
Solution Approach 1:
The patent creates a universal AI system that can handle multiple photo modes by integrating multiple specialized deep learning models. The system includes modules that automatically identify the photo mode of input images and route them to the appropriate analysis model, enabling the system to adapt to various eye image types (mydriatic, small pupil, slit light, diffused light) while maintaining high accuracy for each type.
3Reliability
If prior screening by specialist doctors or technicians is required before AI analysis, then the analysis quality is ensured, but the productivity and accessibility of cataract diagnosis deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the AI system automatically identifies the photo mode of input eye images and selects the appropriate deep learning model for analysis without requiring manual intervention from doctors or technicians. This automation eliminates the need for prior screening by specialists, thereby maintaining diagnosis quality through accurate mode-specific analysis while significantly improving productivity and making the system accessible in primary hospitals with limited medical resources.

AI summary
The invention relates to an artificial intelligence cataract analysis system, including a pattern recognition module for recognizing a photo mode of an input eye image, wherein the photo mode is divided according to the slit width of the illuminating slit during photographing of the eye image and/or whether a mydriatic treatment is carried out; a preliminary analysis module used for selecting a corresponding deep learning model for eye different photo modes, analyzing the characteristics of lens in the eye image by using a deep learning model, and further performing classification in combination with cause and severity degree of a disease. The invention can perform cataract intelligent analysis on eye images with different photo modes by using deep learning models, so that the analysis accuracy is improved.
