VR System for Eye Surgery Vision Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Patients undergoing eye surgeries like cataract or laser vision corrective surgery often make permanent vision-altering decisions without adequate visualization of potential outcomes, relying on conversations or static models, which lacks realism and accuracy.
Innovation Solution
A virtual reality system that generates and displays VR images based on user-specific vision profiles, incorporating corneal aberrations, ocular biometry, scotoma measurements, and accommodation range, allowing users to experience simulated pre- and post-operative visions, enabling informed decision-making.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users rely on conversations with care professionals, pamphlets, or models to understand surgical options, then the information delivery is simple and accessible, but the realism and accuracy of visual outcome prediction is insufficient
Solution Approach 1:
The patent creates virtual copies of the patient's specific eye anatomy using optical coherence tomography (OCT) data and other biometric measurements. These digital models are then used to simulate surgical outcomes, allowing patients to visualize realistic predictions of their post-surgery vision without requiring complex physical prototypes or models.
Solution Approach 2:
The system introduces a computer-generated reality (CGR) intermediary between the patient's current vision and potential surgical outcomes. This virtual reality environment acts as a mediator that translates complex surgical predictions into immersive, intuitive visual experiences that patients can explore interactively.
2Ease of operation
If static models and pamphlets are used to present surgical options, then the system is simple and easy to use, but it lacks interactivity and immersive experience for patients
Solution Approach 1:
The system transforms static visual information into dynamic, interactive virtual reality experiences. Patients can move their heads, change viewing angles, and explore the virtual environment naturally, allowing the simulation to adapt to their movements and provide real-time updates of the surgical outcomes from different perspectives.
Solution Approach 2:
The virtual reality platform serves multiple functions: it educates patients about surgical options, visualizes predicted outcomes, allows interactive exploration, and facilitates informed decision-making. This single system replaces multiple separate tools including pamphlets, models, and consultation processes.
3Measurement precision
If detailed vision profiles incorporating multiple measurements are used, then the accuracy of simulation increases, but the data processing and rendering complexity increases
Solution Approach 1:
The system segments the complex vision simulation into distinct modular components: optical modeling modules that handle different aspects of light propagation, rendering modules that generate images, and analysis modules that process biometric data. This modular architecture allows each component to specialize in specific tasks, reducing overall system complexity while maintaining high precision.
Data Source
AI summary
A vision simulation system may generate a virtual environment. The system may receive a vision profile, where the vision profile includes one or more models providing vision characteristics controlling a rendering of the virtual environment. The system may generate one or more virtual reality (VR) images representative of the virtual environment based on the vision profile. The system may provide the one or more VR images to the headset for display to a user.
