Remote Eye Examination System with Phoropter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current remote eye examination technologies lack comprehensive assessment capabilities, failing to identify ocular health issues beyond refractive errors, and often operate without proper medical guidance, potentially leading to adverse effects and missed diagnoses.
Innovation Solution
A remote comprehensive eye examination system where an ophthalmic technician conducts examinations with a phoropter and management software, transmitting data to a remote optometrist or ophthalmologist for evaluation, ensuring comprehensive ocular health assessments and prescriptions, while complying with telemedicine recommendations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If refraction-based systems are used for remote eye testing, then convenience and accessibility are improved, but comprehensive ocular health assessment capability deteriorates
Solution Approach 1:
The system integrates multiple examination functions (refraction testing, ocular health assessment, disease detection) into a single remote examination platform. The phoropter device is equipped with multiple lenses and optical components that enable both refractive evaluation and comprehensive ocular health assessment through a unified system, allowing one device to serve multiple diagnostic purposes.
Solution Approach 2:
A remote optometrist or ophthalmologist acts as an intermediary between the automated refraction device and the patient. The medical professional remotely controls the phoropter, interprets examination results, and provides comprehensive ocular health assessment, bridging the gap between automated convenience and professional medical judgment.
2Ease of operation
If internet-based refraction tools are used without medical guidance, then accessibility is improved, but patient safety deteriorates
Solution Approach 1:
A licensed optometrist or ophthalmologist serves as a remote intermediary who provides medical guidance throughout the examination process. The medical professional reviews examination results, makes clinical judgments, and determines appropriate prescriptions, ensuring patient safety while maintaining remote accessibility.
Solution Approach 2:
The system implements continuous feedback loops where examination results are immediately reviewed by a remote medical professional who can adjust the examination process, request additional tests, or modify prescriptions based on clinical judgment. This feedback mechanism ensures patient safety by preventing inappropriate prescriptions from unmonitored automated systems.
3Adaptability or versatility
If optometrists are required to be on-site for comprehensive examinations, then comprehensive ocular health assessment is improved, but accessibility and flexibility deteriorate
Solution Approach 1:
The system replaces the mechanical requirement of physical presence with remote electronic communication and telemedicine technology. High-definition video conferencing, digital image transmission, and remote device control enable comprehensive ocular health assessments without requiring the optometrist to be physically present in the examination room.
Solution Approach 2:
Telemedicine technology and digital communication systems act as intermediaries that transmit examination data, images, and video feeds between the local examination site and the remote optometrist. This intermediary technology enables comprehensive assessments to be conducted remotely, maintaining diagnostic quality while improving accessibility.
4Adaptability or versatility
If multiple examination devices are integrated for comprehensive assessment, then diagnostic capability is improved, but system complexity increases
Solution Approach 1:
The system merges multiple examination functions and devices into a single integrated phoropter platform. Refraction testing components, ocular health assessment tools, and digital imaging capabilities are combined in one device, reducing the need for multiple separate equipment pieces while maintaining comprehensive diagnostic capability.
Solution Approach 2:
The phoropter device is designed with universal multi-functionality, incorporating various lenses, filters, and optical components that enable multiple types of examinations (refraction, ocular health assessment, disease screening) through a single device interface, thereby simplifying the overall system while expanding diagnostic capabilities.
Data Source
AI summary
An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.
