Solution Overview
Problem
Current techniques for measuring ocular scattering are ineffective in providing accurate, objective assessments, relying on indirect methods that do not directly quantify scattering, which is crucial for evaluating ophthalmic procedures and their impact on visual performance.
Innovation Solution
A system utilizing two light detectors, one configured to detect light over a narrow angular range and the other over a large angular range, with a processing system to analyze data from both detectors to determine ocular scattering, providing a direct and objective measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single light detector is used to measure ocular scattering, then the device complexity is low, but the measurement precision is insufficient to accurately quantify scattering
Solution Approach 1:
The detection system is segmented into two distinct detectors: a first detector configured to detect light within a first angular range, and a second detector configured to detect light within a second angular range that is larger than the first angular range. This segmentation allows each detector to specialize in capturing specific scattering angles, thereby improving measurement precision without requiring a single overly complex detector
Solution Approach 2:
The patent introduces angular range as an additional dimension for differentiation between detectors. Rather than using a single detector with adjustable parameters, the system employs detectors with fundamentally different angular detection capabilities, transforming the measurement approach from a one-dimensional to a multi-dimensional detection strategy that enhances scattering quantification
2Measurement precision
If indirect methods are used to assess ocular scattering, then the device complexity is low, but the measurement precision and objectivity are insufficient
Solution Approach 1:
The patent replaces indirect mechanical or subjective assessment methods with a direct optical detection system. By using light detectors positioned to capture scattered light at specific angular ranges, the system directly measures scattering effects rather than inferring them from other measurements, thereby improving both precision and objectivity
Solution Approach 2:
The patent introduces light detectors as intermediary devices that directly interact with scattered light from the ocular media. These detectors serve as mediators between the scattering ocular structures and the measurement system, enabling direct quantification of scattering properties without relying on indirect proxies or subjective evaluation

AI summary
Improved systems and methods for determining ocular scattering are provided. These systems and methods can be used to quantify ocular scattering before and/or after a wide variety of different ophthalmic diagnostic procedures, and various surgical and non-surgical treatments. One embodiment provides a system and method for determining ocular scattering that uses two light detectors, with one detector configured to detect light over a relatively narrow angular range, and the other detector configured to detect light over a relatively large angular range. The data from the narrow angular range and the large angular range can then be analyzed to determine a measurement of ocular scattering.
