Variable Laser Arm Lighting for Personalized Ophthalmic Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ophthalmological laser therapy systems fail to account for individual patient responses to color, leading to heightened nervousness and potential detachment of the eye during treatment due to varying psychological effects of color perception.
Innovation Solution
A laser therapy system with a pivotable laser arm featuring a variable lighting arrangement on its outer side, allowing customization of color and brightness based on individual patient preferences or data, to create an optimal psychological state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed blue lighting arrangement is used on the laser arm, then the patient surround provides a calming effect for most patients, but individual patients may experience varying psychological effects including heightened nervousness due to different color perceptions
Solution Approach 1:
The lighting arrangement transitions from a fixed blue color to a dynamic system that can change color and brightness. The control device enables real-time adjustment of lighting parameters based on patient feedback or physiological data, making the system adaptable to individual patient needs while maintaining operational simplicity through automated control.
Solution Approach 2:
The invention changes the lighting parameters from a fixed state to a variable state. The control device allows modification of color temperature, brightness, and color hue to match individual patient preferences or physiological states, resolving the contradiction between adaptability and complexity by providing multiple adjustable parameters under unified control.
2Manufacturing precision
If the laser arm is positioned close to the patient's head for treatment, then precise laser delivery is achieved, but the claustrophobic effect is amplified and patient nervousness increases
Solution Approach 1:
The lighting arrangement uses color changes to psychologically counteract the claustrophobic effect. By adjusting the color and brightness of the lighting on the laser arm, the system creates a more reassuring visual environment for the patient while maintaining the necessary close positioning for precise laser delivery.
Solution Approach 2:
The lighting arrangement acts as an intermediary between the laser arm and the patient. It mediates the psychological impact of the close positioning by providing a controllable visual environment that can reduce anxiety and claustrophobia, allowing the laser arm to maintain its precise positioning without exacerbating patient nervousness.
3Illumination intensity
If the lighting brightness is increased to improve visibility for the operator, then operational visibility is enhanced, but patient anxiety may be heightened due to brighter lighting in the treatment area
Solution Approach 1:
The lighting system implements local quality by providing different illumination levels in different areas. The control device enables selective adjustment of lighting brightness and color temperature to optimize visibility for the operator while creating a calming visual environment for the patient, resolving the contradiction between operational visibility and patient comfort.
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 system minimizes patient anxiety, enhancing cooperation and reducing the risk of premature detachment by providing a personalized calming effect through adjustable lighting.
Implementation Method 1
The lighting arrangement (50) is formed as a self-luminous partial surface of the laser arm
Implementation Method 2
The use of a femtosecond laser, whose emitted laser beam is guided through the laser therapy optical unit and focused in tissue in the eye to be processed, is particularly advantageous. At the focus of the laser beam, this leads to separation of the tissue by application of photodisruption.
