Femtosecond Laser Ophthalmic Surgery Docking Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current femtosecond laser ophthalmic surgery relies on visual inspection for proper placement of the suction cone, which is subjective and prone to errors, affecting the accuracy of the procedure.
Innovation Solution
A system and method that utilize a measuring device, camera, and processor to generate and enhance pictorial representations of the suction ring and eye, providing real-time data and graphics for precise positioning, including a gyroscopic system, ultrasonic system, force transducers, and autofocus cameras, to ensure accurate docking in the x-y plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual inspection by the user is used to guide suction cone placement, then the surgical procedure can be performed, but the placement accuracy is reduced due to subjectivity and human error
Solution Approach 1:
The system provides real-time visual feedback through a display device that shows the relative position of the suction cone to the eye. Cameras capture images from multiple viewpoints, and the processor generates enhanced pictorial representations that guide the user in achieving proper docking alignment, allowing continuous adjustment based on visual information.
Solution Approach 2:
The system introduces an intermediary computational layer between the physical suction cone placement and the final surgical outcome. The processor acts as a mediator that receives data from multiple sensors and cameras, processes this information, and generates enhanced visual representations that more accurately reflect the true alignment status than direct visual inspection alone.
2Measurement precision
If multiple measurement devices and cameras are added to improve positioning accuracy, then placement precision improves, but device complexity increases
Solution Approach 1:
The system employs multiple devices that serve multiple functions simultaneously. For example, the cameras not only capture images for positional measurement but also provide visual feedback for guidance. The processor handles data from various sensors (gyroscopic system, ultrasonic system, force transducers) and generates both measurement data and visual representations, reducing the need for separate dedicated components for each function.
