Automated Ophthalmic Surgery Support Fine Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ophthalmic surgery faces challenges in accurately positioning the eye during procedures due to the sensitivity of vision and minute nature of eye structures, leading to potential errors in alignment and ablation during laser surgeries.
Innovation Solution
An automated system for fine adjustment of the ophthalmic surgery support, incorporating an eye tracking system, a control device, and a processing system that detects the eye's position, determines necessary adjustments, and transmits control signals to center the eye within the detection field of the eye tracking system, either manually or automatically, to ensure precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning of the support is used, then the system is simple to operate, but the alignment precision of the eye is insufficient
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated control system that uses eye tracking data to calculate and execute precise support adjustments. The processing system receives eye position data, determines required adjustments, and transmits control signals to the support's control device, eliminating manual intervention and achieving superior alignment precision through automated feedback control.
2Manufacturing precision
If automated fine adjustment is implemented, then the alignment accuracy is improved, but the device complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically processing eye tracking data and generating control signals without requiring manual intervention. The processing system continuously monitors eye position, calculates necessary corrections, and executes adjustments autonomously, enabling the system to service itself and maintain optimal alignment throughout the surgical procedure.
Solution Approach 2:
The patent implements a closed-loop feedback system where the eye tracking system continuously provides position data to the processing system, which then generates real-time control signals to adjust the support. This feedback mechanism ensures continuous monitoring and correction of eye position, maintaining high positioning accuracy throughout the procedure through dynamic adaptation.
3Productivity
If manual positioning is used, then the system is easier to operate, but the surgical productivity is reduced
Solution Approach 1:
The system performs preliminary positioning adjustments automatically during the initialization phase, centering the eye in the detection field before the surgical procedure begins. This preliminary automated action eliminates time-consuming manual adjustments during surgery, improving surgical efficiency without complicating the actual surgical operation.

AI summary
The present disclosure provides a system for automated fine adjustment of an ophthalmic surgery support in which an eye tracking system detects a detectable position of an eye. The direction and distance the support must be adjusted for the eye to be centered may be determined based on the detectable position. A control signal is generated and transmitted to a control device that adjusts the position of the support to center the eye. The disclosure further provides a method for automated fine adjustment of a support, which includes detecting a detectable position of an eye, determining whether the eye is centered in relation to the center of the detection field of an eye tracking system based on the detectable position, determining a direction and a distance the detectable position must be adjusted to be centered, and generating and transmitting a control signal to adjust the position of the support.
