Ophthalmic Examination System with Shared Optical Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional remote ophthalmic examinations often disrupt the subject's line of sight, making it difficult to provide effective visual instructions and interactive communication without altering their orientation, which hampers the smooth progression of eye examinations.
Innovation Solution
An ophthalmic examination system comprising ophthalmic examination apparatuses and an examination instruction apparatus that enables real-time communication and instruction delivery through a user interface and communication units, allowing interactive communication without changing the subject's face or line of sight, using a shared optical system for examination and information presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If visual instructions are provided to the subject during remote examination, then the examiner can guide the subject through the examination, but the subject must change the orientation of their face or line of sight which interferes with the smooth progress of the test
Solution Approach 1:
A camera is positioned to capture the subject's face, and a display device presents the examiner's visual instructions to the subject. This intermediary system allows the subject to receive instructions without changing their orientation, eliminating the need to look away from the examination target while maintaining smooth communication and examination progress.
2Loss of information
If the examiner provides visual instructions during remote examination, then communication between examiner and subject is established, but the subject's line of sight must be altered which disrupts the examination flow
Solution Approach 1:
The camera and display device create an intermediary visual communication channel that allows the subject to see the examiner's instructions without deviating their gaze from the examination target. This maintains continuous examination flow while ensuring clear communication, eliminating time loss from repeated orientation changes.
3Adaptability or versatility
If conventional remote examination methods are used, then the examiner can conduct the examination remotely, but interactive communication is not possible without changing the subject's orientation
Solution Approach 1:
The camera capturing the subject's face and the display presenting the examiner's visual instructions create an intermediary system that enables natural interactive communication. The subject can see the examiner's gestures and expressions without changing orientation, maintaining the authenticity and quality of interactive communication in remote examination settings.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
According to an ophthalmic examination system of an embodiment, a user interface of an examination instruction apparatus is used to enter an instruction for examination. A first communication unit sends the instruction to an ophthalmic examination apparatus in real time. An examination optical system of the ophthalmic examination apparatus includes an optical element applied to an eye and a projection system that projects an examination light beam onto the eye through the optical element. An information presentation optical system includes a display and a light guide system that guides a display light beam from the display to the eye through the optical element. A second communication unit receives the instruction from the examination instruction apparatus. A controller displays the instruction received by the second communication unit on the display in real time.
