Visual Target Projector for Steady Non-Operative Eye in Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During eye surgery, maintaining the non-operative eye open, steady, and straight is challenging, as it can cause the operative eye to move or close, complicating the procedure and increasing eye pressure.
Innovation Solution
A visual target stimulation device is used, which includes a housing and a visual target projector secured over the non-operative eye to generate a visual target, such as a light, image, or entertainment, to keep the eye focused and steady, while not obstructing the operative eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the non-operative eye is left uncovered and unfocused during surgery, then the patient experiences less discomfort and the device structure remains simple, but the operative eye may move or close due to lack of visual engagement
Solution Approach 1:
The device is divided into separate functional modules: a headrest component, a chin rest component, and a visual target projector. This segmentation allows each component to be optimized independently while working together to solve the eye stability problem without requiring a complex integrated system.
Solution Approach 2:
A visual target projector is introduced as an intermediary element that provides a focal point for the non-operative eye. This mediator engages the patient's visual attention, which indirectly stabilizes the operative eye position through natural physiological coupling of eye movements.
2Ease of operation
If a visual target projector is added to engage the non-operative eye, then the operative eye remains more stable and open, but the device complexity increases
Solution Approach 1:
The visual target projector is designed to automatically adjust its position and focus based on the patient's head position detected by sensors. This self-adjusting capability eliminates the need for manual intervention to maintain proper target alignment, simplifying operation while providing advanced functionality.
Solution Approach 2:
The system incorporates sensors that detect eye position and head orientation, providing real-time feedback to adjust the visual target projection. This closed-loop feedback mechanism ensures the operative eye remains stable and engaged without requiring complex manual control systems.
3Reliability
If the non-operative eye is covered to prevent movement, then the operative eye stability is improved, but the patient loses visual entertainment and comfort
Solution Approach 1:
The visual target projector dynamically adapts its projection characteristics based on real-time detection of eye position and patient response. The system can adjust target size, brightness, and movement patterns to maintain patient engagement and comfort while ensuring operative eye stability throughout the surgical procedure.
Solution Approach 2:
The system changes multiple parameters including projection brightness, target position, and animation patterns to optimize both patient comfort and eye stability. These parameter adjustments are made dynamically during surgery based on detected eye behavior and patient responses.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively keeps the non-operative eye open and steady, reducing the likelihood of the operative eye moving or closing, thereby simplifying the surgery and potentially reducing the need for anesthetic.
Implementation Method 1
a visual target projector attached to the housing and disposed over the non-operative eye. The visual target projector can be configured to generate a visual target on which the non-operative eye focuses during eye surgery

AI summary
A method for eye surgery on an operative eye of an eye surgery patient can comprise a step of securing a monocular device over a non-operative eye of the patient. The monocular device can comprise a frame configured to engage a portion of the patient's face surrounding the non-operative eye and a visual target projector attached to the housing and disposed over the non-operative eye, wherein the monocular device does not cover the operative eye of the patient. The visual target projector can be configured to generate a visual target on which the non-operative eye focuses during eye surgery.
