Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmic image processing methods struggle to display complex eye characteristics in an intuitive manner, making it difficult for non-experts to understand the information and images provided by optometry devices.
Innovation Solution
An ophthalmic image processing method that acquires corneal and refractivity information, generates simulation images of target images at the fundus of the eye, and simultaneously displays an eyeball model image, simulation images, and corneal information images, allowing for a clearer understanding of eye characteristics and the impact of refractive errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple types of ophthalmic information (wavefront aberration analysis map, corneal anterior surface shape analysis map, simulation images) are displayed separately, then comprehensive eye characteristics data is provided, but the information becomes difficult to understand for non-experts
Solution Approach 1:
The patent combines multiple types of ophthalmic information (wavefront aberration analysis map, corneal anterior surface shape analysis map, simulation images) into a single integrated eyeball model image display. This merging allows comprehensive eye characteristics data to be presented in one unified visual interface that is easier to understand, resolving the contradiction between providing complete information and maintaining ease of understanding for non-experts.
Solution Approach 2:
The patent transitions from displaying multiple separate two-dimensional maps to a three-dimensional eyeball model image that integrates all ophthalmic information. This dimensional change allows comprehensive data to be visualized in a spatially organized manner that is more intuitive and easier to comprehend, addressing the understandability issue while preserving all eye characteristics data.
2Measurement precision
If detailed ophthalmic information is displayed in separate maps, then measurement precision is maintained, but device complexity increases
Solution Approach 1:
The patent merges multiple detailed ophthalmic measurement maps into a single integrated display on the eyeball model image. This combination maintains the precision of individual measurements (wavefront aberration, corneal shape, simulation data) while reducing display system complexity by presenting all information in one unified interface rather than multiple separate displays.
3Loss of information
If multiple images are displayed simultaneously on separate screens, then all information is visible, but ease of operation decreases due to complex navigation
Solution Approach 1:
The patent combines all ophthalmic information (corneal information image, simulation image, wavefront aberration analysis map) into a single integrated eyeball model image display. This allows all eye characteristics data to be visible simultaneously in one location, eliminating the need for complex navigation between multiple screens or maps and significantly improving ease of operation.

AI summary
An ophthalmic image processing method includes: acquiring information about characteristics of an examinee's eye including corneal information about the corneal anterior surface shape of the examinee's eye, and refractivity information about refraction of the examinees eye as a whole; generating a simulation image of a target image formed at fundus of the examinee's eye using the refractivity information; and simultaneously displaying an eyeball model image showing an eyeball structure, the simulation image, and a corneal information image associated with the cornea on the eyeball model image and corresponding to the corneal information.
