Ophthalmic Tool Guidance Using Predictive Eye Surgery Modeling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye surgery systems lack precision in surgical procedures due to the lack of accurate assessment and guidance of surgical tools during operations, leading to unsatisfactory results such as incorrect incisions and improper implant positioning.
Innovation Solution
An eye surgery operating system with a computer unit that continually acquires measurement data to create models of the operating site and area of effect, providing assessment information for surgical tool guidance, considering the dynamics of the system and predicting the surgical outcome to ensure precise tool placement and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional surgical guidance methods are used, then the surgical procedure can be performed, but the precision of surgical tool placement and the accuracy of surgical outcomes are insufficient
Solution Approach 1:
The system creates a preoperative 3D model of the patient's eye and plans the surgical procedure in advance, determining optimal incision positions and implant orientations before the actual surgery. This preliminary modeling and planning enables precise surgical tool placement by providing a digital roadmap that guides the surgeon throughout the procedure.
Solution Approach 2:
The system continuously acquires measurement data during surgery and compares the actual surgical tool position and surgical outcomes against the preoperative 3D model and planned parameters. This real-time feedback mechanism allows for immediate assessment of surgical precision and enables adjustments to achieve the desired surgical outcome.
2Adaptability or versatility
If static preoperative planning is used, then the surgical plan can be established, but it cannot adapt to dynamic changes in the operating site during surgery
Solution Approach 1:
The system transitions from static preoperative planning to dynamic intraoperative modeling by continuously acquiring measurement data during surgery. The 3D model of the operating site is updated in real-time to reflect actual anatomical variations and surgical progress, enabling the surgical plan to adapt to dynamic changes while maintaining temporal efficiency through automated data processing.
3Manufacturing precision
If detailed continual measurement data acquisition is implemented, then surgical precision is improved, but the system complexity and data processing requirements increase
Solution Approach 1:
The computer unit integrates multiple functions including 3D model creation, real-time data acquisition, surgical plan comparison, and outcome assessment into a single unified system. This multi-functional approach consolidates complex data processing tasks and reduces overall system complexity by eliminating the need for separate specialized devices for each function.

AI summary
An ophthalmic surgery operating system comprises a surgical tool to act on a region of action, which is a spatially extended region of possible actions of the surgical tool within a time window of action. A computer program includes a surgical tool program routine for providing a model of the region of action and a routine for determining the spatial position of the model of the operating site with respect to the model of the region of action from the reference measurement data. The computer program has a prognosis routine that determines, from the spatial position of the model of the operating site with respect to the spatial position of the model of the region of action, a continuously adapted model, valid for a time interval that includes the time window of action, concerning the predicted result of the surgical operation on the patient's eye.
