A system for non-invasive treatment of a patient's trabecular meshwork to treat primary open-angle glaucoma. The system and technique applies energy directly to media within clogged spaces in a patient's trabecular meshwork to increase aqueous outflow facility by (i) localization of microimplantable bodies carrying a selected exogenous chromophore, such as particles with a gold surface, in deeper regions of the trabecular meshwork, and (ii) irradiation of the microimplantables with a selected coherent wavelength having a power level and pulse duration that is strongly absorbed by the surfaces of the microimplantables.
