Myopia Control Algorithm Using Individual and Environmental Scores
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining myopia control solutions are subjective and non-uniform, relying on the experience and knowledge of eye care professionals, which can lead to variations in efficacy for different subjects over time.
Innovation Solution
A system and method that objectively determine a myopia control solution for a subject by calculating individual and environmental scores based on specific features and parameters, allowing for the recommendation of the most appropriate solution and any necessary modifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If myopia control solution determination is based on eye care professional experience and knowledge, then the solution can be customized to individual subjects, but the determination process becomes non-uniform and subjective leading to variability in efficacy
Solution Approach 1:
The patent transforms the subjective determination process into an objective one by changing the parameters from professional experience-based judgment to quantifiable scores. Individual features (age, sex, family history, ocular biometrics) and environmental parameters (near work, outdoor time, lighting) are converted into numerical values that are processed algorithmically to generate standardized myopia risk scores, eliminating subjectivity while preserving individualization.
Solution Approach 2:
The patent replaces the mechanical system of human professional judgment with an automated computational system. The eye care professional's experience-based decision-making is substituted by a processor-executed algorithm that objectively calculates myopia risk scores based on input parameters, providing consistent and reproducible results across different practitioners and settings.
2Ease of operation
If traditional subjective methods are used to determine myopia control solutions, then implementation is simpler, but monitoring and adjusting efficacy over time becomes less reliable
Solution Approach 1:
The patent implements a feedback mechanism where myopia risk scores are calculated at multiple time points (baseline and follow-up) to monitor the efficacy of the myopia control solution. The system compares the change in myopia risk score before and after intervention to objectively assess whether the solution is effective, providing reliable feedback for adjusting or maintaining the treatment plan.
3Measurement precision
If myopia control solutions are selected based on uniform protocols, then determination becomes more objective, but adaptability to individual subject characteristics decreases
Solution Approach 1:
The patent applies local quality by weighting different individual and environmental parameters according to their specific importance for each subject. Not all features contribute equally to myopia risk; the system assigns differential weights to parameters such as family history, ocular biometrics, and environmental exposures based on their relative significance, allowing the standardized protocol to capture individual variations in myopia susceptibility.

AI summary
A system for determining a modification of an initial myopia control solution used by a myopic subject, comprising one or more memories having in memory values of individual features of said myopic subject and values of environmental parameters relative to conditions of use by said myopic subject of said initial myopia control solution and comprising one or more processors programmed to: determine an individual score linked to a role of said individual features in causing the myopia of said myopic subject, said individual score depending on said values of individual features, determine an environmental score linked to a role of said environmental parameters in causing the myopia of said myopic subject, said environmental score depending on said values of said environmental parameters, and determine said modification of said initial myopia control solution for said subject based on said individual and environmental scores.
