Solution Overview
Problem
Current eye surgery systems lack the capability to simultaneously or consecutively display intraoperative OCT images, preoperative OCT images, and light-optical images of the eye fundus during surgical interventions, making it difficult for surgeons to assess the success of procedures and plan further measures effectively.
Innovation Solution
An eye surgery system comprising microscopy optics and an OCT device, with a controller and visualization system that allows for the simultaneous or consecutive display of intraoperative OCT images, preoperative OCT images, and light-optical images, adjusting magnification and orientation to facilitate comparison and improve surgical planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple images (intraoperative OCT, preoperative OCT, and light-optical images) are displayed simultaneously or consecutively, then the ability to assess surgical success and plan further measures is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple imaging modalities (OCT device and microscopy optics) into a single integrated eye surgery system, allowing simultaneous acquisition and display of intraoperative OCT images, preoperative OCT images, and light-optical images. This merging eliminates the need for separate imaging systems and enables comprehensive surgical assessment through unified image presentation.
Solution Approach 2:
The visualization system is designed to perform multiple functions: displaying intraoperative OCT images, preoperative OCT images, and light-optical images simultaneously or consecutively. The system can also adjust magnification and orientation of different images, providing a universal platform for comprehensive surgical evaluation and planning.
2Ease of operation
If images are adjusted to the same magnification and orientation for comparison, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The visualization system dynamically adjusts the magnification and orientation of displayed images to ensure they are comparable. The system can change these parameters in real-time based on the surgical context, allowing surgeons to easily compare images at matching scales and orientations without manual intervention.
Solution Approach 2:
The system automatically modifies display parameters (magnification and orientation) of different images to enable direct comparison. By changing these parameters dynamically, the system ensures that intraoperative and preoperative images are presented at consistent scales and angles, facilitating ease of surgical assessment.
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
Enables surgeons to observe and compare images effectively, enhancing the assessment of surgical interventions and planning by ensuring that all images are displayed at the same magnification and orientation, allowing for better decision-making during procedures.
Implementation Method 1
an interference of measurement light reflected or backscattered from the eye fundus with measurement light having passed the reference path is detected
Implementation Method 2
an image of the eye fundus is transmitted by the ocular and projection optics to the beam combining element

AI summary
An eye surgery system 1 comprises microscopy optics 3 and an OCT device 5 to generate a light-optical image and an OCT image of an eye fundus 11, a controller 29 and a visualization system 13, 41, 83. The controller comprises a data interface 97 for receiving a preoperative OCT image and may control the visualization system to display a representation of the received preoperative OCT image. The controller may control the OCT device 5 to record an intraoperative OCT image and may control the visualization system to display a representation of the recorded intraoperative OCT image. The controller may adjust a magnification of the representation of the intraoperative OCT image and/or a magnification of the representation of the preoperative OCT image so that the magnifications of the representation of the intraoperative OCT image and the magnification of the representation of the preoperative OCT image are equal.
