Laser trabeculodissection

摘要

This invention contemplates the use of a surgical laser device characterized by ultra-violet or infrared radiation to achieve controlled trabeculodissection in selected regions of the trabecular meshwork and Schlemm's Canal. The surgical laser is positioned over the corneoscleral bed for non-contact delivery, or, alternatively, it is inserted under a sclera flap with a contact tip and laser radiation is directed toward the trabecular meshwork and canal of Schlemm creating an ultra-thin trabecular meshwork and Canal of Schlemm. The outflow of aqueous humor through the disected trabecular meshwork functions as a self-limiting end point to the surgery when the aqueous humor absorbs the laser energy.
