Laser Marking for Ocular Alignment Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current eye surgery techniques face challenges in achieving precise alignment and minimizing unintended side effects, particularly in procedures that require accurate optical axis alignment and correction of refractive errors, leading to potential optical aberrations and reduced effectiveness.
Innovation Solution
The method involves determining specific optical characteristics of the eye, such as axes, and using laser marking pulses to create precise marks on the eye, allowing for improved alignment and surgical precision during procedures like intraocular lens placement and corneal inlays, using a pulsed laser system with an imaging module to monitor and control the alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional eye surgery techniques are used, then surgical procedures can be performed, but precise alignment with optical axes is difficult to achieve, leading to unintended side effects and optical aberrations
Solution Approach 1:
The system performs preliminary laser marking of the eye's optical axes and key anatomical landmarks before the main surgical procedure. This preliminary action creates reference marks that guide subsequent surgical interventions, ensuring precise alignment with the eye's optical characteristics and minimizing unintended side effects.
Solution Approach 2:
The system incorporates real-time imaging and tracking that monitors the eye's position and orientation during surgery. This feedback mechanism allows the surgical system to adjust and maintain precise alignment with the optical axes throughout the procedure, correcting for any eye movement or positional changes.
2Manufacturing precision
If laser marking pulses are applied to create precise marks, then surgical alignment is improved, but the complexity of the surgical system increases
Solution Approach 1:
The surgical system integrates multiple functions into a single platform: laser marking, imaging, tracking, and surgical intervention. This multi-functionality reduces the need for separate devices and simplifies the overall surgical workflow while maintaining high precision alignment through coordinated operation of all components.

AI summary
Techniques, systems are described for performing laser eye surgery. In one aspect, a method for improving an optical function of an eye includes preparing the eye for surgery by determining an optical characteristic of the eye. Laser marking pulses are applied to generate a laser mark in a region of the eye in relation to the determined optical characteristic. Also, a surgical procedure is performed in a surgical region selected in relation to the generated laser mark.
