Ophthalmic Suction Ring Docking via Iris Tracking Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ophthalmic surgery is challenging due to the sensitivity and delicacy of eye structures, requiring precise placement of surgical instruments like the suction ring to ensure accurate and effective procedures, which is difficult without proper guidance.
Innovation Solution
A system using image sensors and graphic overlays to determine the location of the iris and suction ring, providing real-time guidance for precise placement and orientation, aiding surgeons in docking the suction ring correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual placement of suction ring is performed without guidance, then device complexity is reduced, but manufacturing precision and measurement precision deteriorate
Solution Approach 1:
The system captures real-time images of the eye and suction ring position, processes this visual feedback, and displays it to the surgeon to enable precise docking. The feedback loop allows continuous adjustment of suction ring position based on observed alignment with iris structures
Solution Approach 2:
A camera system acts as an intermediary between the surgeon and the eye, capturing visual information that would otherwise be difficult to observe directly. The camera provides an enhanced view that enables precise placement without requiring complex mechanical guidance systems
2Measurement precision
If image sensors and graphic overlays are used to guide suction ring placement, then measurement precision and positioning accuracy are improved, but device complexity increases
Solution Approach 1:
The system creates a visual copy of the eye structure through imaging and displays it with graphic overlays showing the desired suction ring position. This visual copy allows the surgeon to plan and execute precise docking without complex mechanical guidance systems
Solution Approach 2:
The system changes the visual parameters of the displayed image by adding graphic overlays that highlight key anatomical landmarks and desired placement positions. This parameter change in the visual information enables precise positioning without increasing physical device complexity
3Manufacturing precision
If real-time imaging and graphic overlays are implemented, then surgical accuracy is improved, but loss of time in image processing and display increases
Solution Approach 1:
The system captures images and prepares graphic overlays in advance of the actual docking procedure. By performing these actions preliminarily, the system minimizes time delays during the critical docking moment while still providing accurate visual guidance

AI summary
The disclosure provides a system that may acquire, via an image sensor, an image of an eye of a person; may determine a location of an iris of the eye from the image; may determine a position of a suction ring from the image; may display, via a display, the image; may display, via the display, a first graphic overlay on the image that indicates the location of the iris of the eye; may display, via the display, a second graphic overlay on the image that indicates the position of the suction ring; may determine multiple iris structures from the image; may determine an orientation of the eye based at least on the multiple iris structures from the image; and may display, via the display, information that indicates the orientation of the eye.
