Surgical Microscope Overlay for Eye Positioning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical treatments for the eye, such as intraocular lens implantation, face challenges in accurately positioning incisions and implants due to the reliance on external markers, which can be imprecise and require additional steps during the procedure.
Innovation Solution
An arrangement that uses a diagnostic instrument to register eye-structure data, including biometric and image data, which is processed to generate a structural image that can be faded into the surgical microscope's view, providing positional markings for precise placement without the need for external markers, and includes features like image superimposition, light accentuation, and automatic positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external markers are placed onto the eye for positioning, then the surgical procedure can be performed, but the positioning accuracy is imprecise and additional steps are required
Solution Approach 1:
The patent creates a digital copy of the eye's structural data from preoperative imaging and overlays it with virtual markers in the surgical field of view. This virtual marker system replaces physical external markers, providing precise positioning information directly in the surgeon's view without requiring additional physical marking steps on the patient's eye.
Solution Approach 2:
The patent introduces an intermediary software system that processes imaging data, generates structural models, and overlays virtual markers onto the surgical view. This intermediary layer bridges the gap between preoperative planning and intraoperative execution, enabling accurate positioning without direct physical marker placement on the eye.
2Manufacturing precision
If external markers are used for positioning incisions and implants, then the surgical treatment can be carried out, but the placement accuracy is reduced
Solution Approach 1:
The patent replaces the mechanical system of physical markers placed on the eye surface with an optical/digital system. Virtual markers are rendered through image processing and overlay techniques, eliminating the mechanical limitations of physical marker placement and providing sub-millimeter positioning accuracy through digital precision.
Solution Approach 2:
The patent transitions from two-dimensional physical markers on the eye surface to three-dimensional spatial positioning through volumetric imaging data. The structural model incorporates depth information and spatial relationships from multiple imaging planes, enabling precise placement accuracy that extends into the third dimension.

AI summary
An arrangement for carrying out a surgical treatment of an eye includes a diagnostic instrument which is adapted to register eye-structure data. A data processing unit is adapted to generate, on the basis of the eye-structure data registered by the diagnostic instrument, a structural image that contains at least one mapping of a characteristic eye structure and also at least one positional marking arranged relative to the mapping of the characteristic eye structure. An image-data fade-in device is adapted to fade the structural image generated by the data processing unit into an image generated by a surgical microscope during the implementation of a surgical treatment of the eye.
