Eye Surgery Visualization System Image Orientation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Eye surgery visualization systems often present observers with images of a patient's eye that have different orientations within and outside the ophthalmoscopy loupe, leading to incorrect lateral imaging, which complicates instrument insertion during surgeries.
Innovation Solution
An eye surgery visualization system with an image sensor, imaging system, and computer unit that processes images captured by both sensors, separating and mirroring image portions to combine them into a single, laterally correct image, using an ophthalmoscopy loupe and image processing routine to correct orientation issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an ophthalmoscopy loupe is used to image a portion within a patient's eye, then magnification and detailed observation are improved, but image orientation becomes incorrect (laterally inverted) relative to the rest of the object region
Solution Approach 1:
The image captured by the image sensor is segmented into first portions (through the ophthalmoscopy loupe) and second portions (outside the loupe). This segmentation allows different processing to be applied to each region, enabling the inverted portions to be corrected while preserving the magnified view through the loupe.
Solution Approach 2:
The image processing routine inverts the first portions of the image that were captured through the ophthalmoscopy loupe. This inversion corrects the lateral inversion caused by the loupe, making the orientation consistent with the second portions and enabling intuitive instrument insertion without mirror-inverted movement.
2Measurement precision
If image portions through the ophthalmoscopy loupe are displayed with their original orientation, then the magnified view is preserved, but the overall image has inconsistent orientation between different regions
Solution Approach 1:
The image is divided into first portions (through loupe) and second portions (outside loupe), allowing selective processing of the magnified regions while maintaining overall image coherence.
Solution Approach 2:
By inverting only the first portions that were captured through the ophthalmoscopy loupe, the orientation consistency across the entire image is restored while preserving the magnification benefit.
3Measurement precision
If the surgeon operates based on the laterally inverted image from the ophthalmoscopy loupe, then detailed observation is possible, but instrument insertion requires mirror-inverted movement which reduces operational accuracy
Solution Approach 1:
The image processing routine inverts the first portions to correct the lateral inversion, enabling the surgeon to move instruments in the same direction as the image movement, thereby improving instrument insertion precision while maintaining detailed observation capability.

AI summary
An eye surgery visualization system includes an image sensor and contains an imaging system for producing an image of an object region with an optical imaging beam path in an imaging plane on an image sensor. A computer unit has an image processing routine for an image of the object region, the image having been captured by the image sensor. An image display unit visualizes image data of an image processed in the computer unit. An ophthalmoscopy loupe of the system images a portion lying within a patient's eye in an intermediate image plane that is conjugate to the imaging plane on the image sensor. The image processing routine separates the first portions of the image of the object region from second portions of the image of the object region in the imaging plane on the image sensor.
