Vision Training Apparatus for Strabismus Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for strabismus, such as vision training therapy and surgical intervention, have limitations including high costs, time-consuming processes, and unsuitability for children and adolescents with mild deviations, as well as potential side effects from surgical methods.
Innovation Solution
A vision training device and method that includes a storage unit for storing deviation angle information and a control unit to guide eye movement based on the deviation angle, using a strabismus correction value to determine a training range and guide eye movement in a direction opposite to the deviation, thereby improving strabismus symptoms without surgical intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical intervention is used to treat strabismus, then the deviation angle can be corrected, but it requires general anesthesia which poses risks of side effects for children and adolescents
Solution Approach 1:
The patent replaces the mechanical/surgical intervention system with an optical training system. Instead of using surgical instruments to physically adjust eye muscles, the system uses optical prisms and visual training exercises to gradually correct strabismus through neural adaptation and muscle conditioning, thereby eliminating anesthesia risks
Solution Approach 2:
The training system enables patients to perform self-training through home exercises guided by the system. The device provides automated guidance and monitoring, allowing patients to independently complete training routines without requiring repeated surgical intervention or professional clinical procedures
2Reliability
If surgical intervention is used to treat strabismus, then the deviation angle can be corrected, but it is only possible for patients with a deviation angle of 15 prism diopters or more, making it unsuitable for children and adolescents with smaller angles
Solution Approach 1:
The system dynamically adjusts training parameters including prism diopter values, training duration, and exercise intensity based on the patient's specific deviation angle. This allows the same training system to effectively treat patients across the full spectrum of strabismus severity, from mild deviations under 15 prism diopters to more severe cases
Solution Approach 2:
The training program is highly adaptable and can be dynamically adjusted for each patient based on their age, deviation angle, and progression rate. The system provides customized training routines that evolve over time as the patient improves, making it suitable for diverse patient populations including children and adolescents with varying severity levels
3Reliability
If vision training therapy is conducted at vision training centers, then strabismus can be treated, but it requires patients to visit the center over a long period, increasing time consumption and cost
Solution Approach 1:
The system enables patients to perform self-training through home exercises, eliminating the need for repeated visits to vision training centers. The device provides automated guidance, progress monitoring, and adaptive training routines that can be completed independently, significantly reducing time and cost while maintaining treatment effectiveness
Solution Approach 2:
The patent replaces the manual clinical therapy system with an automated optical training system. Instead of requiring manual guidance and monitoring by vision therapists during each session, the system uses computer-controlled prisms, visual feedback mechanisms, and software algorithms to automatically adapt and monitor training progress, enabling efficient home-based treatment
4Reliability
If surgical methods are used to treat strabismus, then the deviation can be corrected, but the stronger muscles around the eye are weakened, leading to overall weakening of the eye muscles
Solution Approach 1:
The system replaces surgical muscle manipulation with optical training that strengthens eye muscles through controlled visual exercises. By using prisms to create controlled visual discrepancies and requiring the muscles to work harder to maintain proper eye alignment during training exercises, the system actually strengthens rather than weakens the eye muscles

AI summary
A vision training device according to an embodiment of the present invention includes a deviation angle determining unit that determines a deviation angle and a deviation direction of a user, a strabismus correction value determining unit that determines at least one or more correction prism diopters and a correction direction based on the deviation angle and the deviation direction, a vision training unit that determines at least one of the correction prism diopters as a training range and guides movement of the user's eye in the deviation direction and the correction direction, and a refraction angle adjusting unit that changes a refraction angle of light entering the user's eye according to the deviation angle or at least one or more correction prism diopters included in the training range. Through vision training, weak eye muscles, which are the root cause of strabismus, can be strengthened.
