Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ophthalmic surgical laser systems lack versatility, flexibility, and customization capabilities, as well as effective networking for sharing and validating surgical profiles, which limits their ability to adapt to individual patient needs and ensures safety and efficacy.
Innovation Solution
A method and system for generating, simulating, and validating customized ophthalmic surgical profiles, including a pattern definition engine, simulation engine, and validation engine, which create a pattern definition file that calculates laser scan coordinates and pulse energy, and validates the profile against predetermined thresholds to ensure safety and efficacy, allowing for customization and sharing of surgical patterns and parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If customized surgical profiles are created to improve versatility and adaptability, then the ability to adapt to individual patient needs is improved, but the complexity of validating and ensuring safety increases
Solution Approach 1:
The system performs preliminary validation through simulation before actual surgical execution. The validation engine simulates the customized surgical profile's execution and validates parameters such as surgical volume, total energy, and procedure time against predetermined thresholds, ensuring safety before the procedure is performed on the patient.
Solution Approach 2:
The validation engine acts as an intermediary between the customized surgical profile creation and actual execution. It mediates by simulating the profile's effects and verifying that all parameters remain within safe thresholds, thereby enabling customization while maintaining safety controls.
2Reliability
If simulation and validation processes are implemented to ensure safety, then reliability is improved, but the procedure time and complexity increase
Solution Approach 1:
The simulation and validation are performed preliminarily on virtual models and predefined parameters before actual surgical execution. By validating the surgical profile in advance, the system ensures safety without adding time during the actual procedure, as the validation occurs during the planning and preparation phase.
Solution Approach 2:
The system creates a virtual copy of the surgical procedure through simulation. Instead of testing on actual tissue, the validation engine simulates the surgical profile's execution on a digital model, validating all critical parameters without consuming actual surgical time or resources.
3Manufacturing precision
If comprehensive validation of surgical parameters is performed, then manufacturing precision is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The validation engine focuses on validating specific critical parameters (surgical volume, total energy, procedure time) rather than all possible parameters. This localized approach to validation ensures surgical precision for the most critical aspects while avoiding unnecessary complexity from validating every conceivable parameter.
Solution Approach 2:
The system validates surgical profiles by checking whether parameters remain within predetermined thresholds. The validation engine compares simulated parameter values against established safe ranges, ensuring precision through parameter constraint verification rather than through complex real-time monitoring of all system variables.

AI summary
A customized surgical profile is validated for execution on a surgical system. In some aspects, a customized ophthalmic surgical profile, which includes a surgical pattern and at least one parameter associated with the surgical pattern, is obtained. A pattern definition file executable by a laser-based ophthalmic surgical system is generated based on the customized ophthalmic surgical profile. Execution of the customized ophthalmic surgical profile on the laser-based ophthalmic surgical system is simulated based on the pattern definition file, and the pattern definition file is validated based on an output of the simulation.
