This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,462.

Summary of the Inventive Concept

A novel laser eye surgery system incorporating advanced features to improve accuracy, safety, and efficiency, addressing the limitations of existing systems.

Background and Problem Solved

The original laser eye surgery system patent disclosed a method for performing laser eye surgery while accommodating patient movement. However, the system had limitations in terms of accuracy, safety, and efficiency. The new inventive concept addresses these limitations by introducing novel dynamic stabilization, predictive modeling, self-calibration, emergency shutdown, and adaptive optics features to enhance the overall performance of the laser eye surgery system.

Detailed Description of the Inventive Concept

The advanced laser eye surgery system comprises a laser beam source, an objective lens, a scanning assembly, and a free-floating mechanism providing a variable optical path. The free-floating mechanism includes a novel dynamic stabilization system to minimize movement-induced errors, a predictive modeling algorithm to anticipate and correct for patient movement, a self-calibration feature to ensure optimal system performance, an emergency shutdown system to rapidly terminate the laser beam in response to unexpected patient movement, and an adaptive optics system to compensate for aberrations in the eye and improve treatment outcomes.

Novelty and Inventive Step

The new inventive concept introduces a novel combination of advanced features that improve the accuracy, safety, and efficiency of laser eye surgery systems. The dynamic stabilization, predictive modeling, self-calibration, emergency shutdown, and adaptive optics features are non-obvious and novel compared to the original patent, providing a significant inventive step.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying the design of the free-floating mechanism, using different types of sensors and algorithms for predictive modeling, or incorporating additional safety features such as redundant emergency shutdown systems. Variations could also include adapting the system for use in other medical procedures or applications.

Potential Commercial Applications and Market

The advanced laser eye surgery system has significant commercial potential in the ophthalmology and medical device industries. The system's enhanced accuracy, safety, and efficiency features could make it an attractive option for medical professionals and patients, potentially expanding the market for laser eye surgery procedures.
