Eye Surgery Overlay System for Precise Incision Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for eye treatments, such as intraocular lens implantation, face challenges in accurately positioning incisions and implants due to the need for manual alignment and the use of markers, which can be imprecise and cumbersome.
Innovation Solution
An arrangement that uses a diagnostic device to record eye structure data and biometric data, generating a structural image that can be overlaid onto the surgical microscope's image, providing precise positioning markings without the need for physical markers, and allowing for automatic alignment using an eye tracker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If markers are placed on the eye to serve as positioning aids during surgery, then the surgeon can identify incision and implant positions, but the positioning accuracy is reduced and the procedure becomes more cumbersome
Solution Approach 1:
The patent creates a digital copy of the patient's eye anatomy through 3D imaging and generates virtual markers that are overlaid onto the live microscope view. This virtual marker system replaces physical markers, providing precise positioning information without requiring actual marker placement on the eye, thereby maintaining high positioning accuracy while simplifying the surgical procedure
Solution Approach 2:
The patent replaces the mechanical system of physical marker placement with a digital/image-based system. The overlay unit superimposes virtual markers generated from 3D reconstructed eye anatomy onto the live microscope image, eliminating the need for manual marker application and providing more accurate and reliable positioning information
2Manufacturing precision
If manual alignment methods are used to position surgical markers, then the procedure can be performed with simple equipment, but the time required for alignment increases and precision is reduced
Solution Approach 1:
The patent employs real-time feedback through the overlay unit that continuously superimposes virtual markers onto the live microscope view. The system compares the planned incision and implant positions (from 3D reconstruction) with the actual live view, providing immediate visual feedback to guide precise surgical placement without time-consuming manual alignment procedures
Solution Approach 2:
The patent performs preliminary 3D reconstruction of the eye anatomy and pre-calculates the optimal incision and implant positions before the actual surgical intervention. This preliminary planning phase allows the system to provide ready-to-use virtual markers during surgery, eliminating the need for time-consuming intraoperative alignment procedures
3Reliability
If physical markers are used for positioning, then the system is simple to implement, but the reliability and consistency of positioning information is reduced
Solution Approach 1:
The patent creates a multi-functional arrangement where a single integrated system performs 3D imaging, anatomical reconstruction, virtual marker generation, and real-time overlay display. This universal system replaces multiple separate components (physical markers, alignment tools, separate imaging devices) with one cohesive digital platform, improving reliability through consistent digital positioning information while the integration manages the complexity
