Abstract: The present invention enables assisting in manipulation and movement of intraocular particles in order to treat various ocular conditions. It enables controlling intra-ocular particles using acoustic wave forces. The novel technique of the present invention utilizes acoustic radiation forces for non-invasive control over movement of the pathologic intraocular particles, preventing them from unwanted accumulation and obstruction of intraocular structures, or causing visual disturbances. Acoustic forces can be harnessed to non-invasively organize various types of endogenous and exogenous particles within the anterior chamber of the eye, without any sign of tissue damage.
