Abstract
A system for non-invasive treatment of a patient's trabecular meshwork to treat primary open-angle glaucoma, exfoliation glaucoma and pigmentary glaucoma wherein the meshwork can be clogged with cellular debris and other accumulations. 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 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 exogenous chromophore. The chromophores are preferably carried in uniform nanocystalline particles having an average diameter ranging from about 0.5 nm to 20 nm. Thermoelastic expansion of the nanoparticles can propagate .+-.10 atm bipolar stress waves in the surrounding fluid media thereby causing microcavitation thereby delivering mechanical energy to ablate debris and accumulations in the meshwork without causing thermal damage to the trabecular meshwork sheets.
