Enhanced Methods for Glaucoma Treatment using Ultrashort Laser Pulses

The inventive concept improves upon the original patent by introducing advanced laser-based systems and methods for treating glaucoma, enhancing visualization, reducing thermal damage, and optimizing photodisruptive removal of outflow obstructing tissues.

The original patent described methods for treating glaucoma using visible and infrared ultrashort laser pulses. However, the existing approach has limitations, such as inadequate visualization of Schlemm's canal during treatment, potential thermal damage to surrounding tissue, and lack of real-time control over laser pulses. The new inventive concept addresses these limitations by introducing enhanced systems and methods that improve the safety, efficiency, and effectiveness of glaucoma treatment.

The inventive concept comprises advanced laser-based systems and methods that build upon the original patent. The new claims introduce a system for treating glaucoma that incorporates a laser device emitting ultrashort pulses, a goniolens or fiberoptic element for precise targeting, and an optical coupling system to control localized and diffuse pressure gradients. Additionally, the inventive concept includes methods for enhancing visualization of Schlemm's canal during treatment, reducing thermal damage, and optimizing photodisruptive removal of outflow obstructing tissues. These advancements enable real-time visualization of Schlemm's canal, minimize heat generation, and ensure precise and controlled removal of obstructing tissues.

The new claims introduce novel and non-obvious improvements over the original patent, including the use of optical coherence tomography or photoacoustic spectroscopy for real-time visualization, pulse duration control for optimized photodisruption, and feedback control systems for precise laser pulse adjustment. These advancements provide a significant inventive step beyond the original patent.

Alternative embodiments of the inventive concept could include the use of different laser wavelengths, pulse durations, or optical systems. Variations could also involve the integration of additional sensors or imaging modalities to further enhance visualization and treatment outcomes.

The inventive concept has significant commercial potential in the ophthalmic industry, offering improved glaucoma treatment options for patients. The enhanced systems and methods could be marketed as premium offerings, providing a competitive advantage for companies adopting this technology.
