Innovation Solution
An ophthalmic observation apparatus that stores operation mode information associating each mode with specific operational details, allowing automatic execution of designated modes, including fixation directions, scanning patterns, image types, analytic processes, and output layouts, enabling easy and accurate acquisition of diagnostic information without excess or deficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used to set various parameters for accurate diagnosis, then diagnostic accuracy can be maintained, but operation efficiency decreases and requires experienced personnel
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple operation modes (fundus examination mode, OCT examination mode, slit lamp examination mode, etc.) with all necessary parameter settings stored in advance. When a mode is selected, the system automatically retrieves and applies the pre-stored parameters, eliminating the need for manual setup and ensuring diagnostic accuracy without requiring experienced personnel to configure each parameter manually.
2Adaptability or versatility
If manual operation is used to set various parameters, then flexibility in parameter adjustment is maintained, but operation complexity increases and requires experienced personnel
Solution Approach 1:
The patent implements universality by creating a multi-functional operation mode selection system where a single interface (mode selection unit) provides access to multiple pre-configured examination modes. Each mode encompasses multiple functions and parameters specific to different ophthalmic examinations, allowing the system to adapt to various diagnostic needs while maintaining simple operation through unified mode selection rather than individual parameter control.
3Ease of operation
If automatic execution of operation modes is implemented, then operation efficiency improves and ease of operation increases, but device complexity increases due to storage and control requirements
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple operation modes (fundus examination mode, OCT examination mode, slit lamp examination mode, etc.) with all necessary parameter settings stored in advance. When a mode is selected, the system automatically retrieves and applies the pre-stored parameters, eliminating the need for manual setup and ensuring diagnostic accuracy without requiring experienced personnel to configure each parameter manually.
Solution Approach 2:
The patent implements copying by creating standardized operation mode templates that can be stored and reused. Each operation mode represents a copied configuration of parameters, scanning patterns, and analysis settings that can be instantly applied without manual recreation. This allows the system to maintain simplicity while providing automated execution through pre-copied mode definitions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus enables automatic execution of designated operation modes, facilitating easy and accurate acquisition of diagnostic information for eye examinations, reducing the risk of errors and improving efficiency by automating the process based on pre-stored operational details.
Implementation Method 1
divides low coherence light into signal light and reference light, causes signal light that has passed through subject eye to overlap with reference light to generate interference light
Implementation Method 2
configured to form images of a subject eye by using optical coherence tomography (OCT)

AI summary
An ophthalmic observation apparatus 1 performs an OCT measurement of a fundus Ef to form an OCT image, performs an analytical processing on this OCT image, and outputs examination-results information including the analysis results. The ophthalmic observation apparatus 1 is capable of selectively executing a plurality of operation modes. The ophthalmic observation apparatus 1 preliminarily stores operation mode information 214, in which various operational details are associated with each operation mode. When one operation mode is designated, the ophthalmic observation apparatus 1 refers to the operation mode information 214 to identify the operational details associated with this operation mode, and controls an optical system, an image forming part 220, a three-dimensional image forming part 231, an analytic processor 232, a display 240, and/or a printer 300, etc. based on the identified operational details.
