The present invention provides devices and methods for non-invasively lowering intraocular pressure. In particular, some non-invasive intraocular pressure lowering devices of the invention comprise an oscillating element having a proximal end and a terminal probe. Typically, the terminal probe of said oscillating element comprises a substantially non-abrasive material that is adapted to be in contact with an ocular surface without causing any significant damage to the tissue and is shaped to conform to ocular surface at the limbal region. Devices also include an oscillating mechanism that is operatively connected to the proximal end of said oscillating tip such that when oscillating mechanism is in operation said oscillating tip moves axially without damaging ocular cells. Intraocular pressure lowering devices of the present invention are capable of non-invasively transmitting mechanical force to the tissue proximate to the limbal tissue.

La présente invention concerne des dispositifs et des procédés permettant d'abaisser la pression intraoculaire de manière non invasive. En particulier, certains dispositifs d'abaissement de pression intraoculaire non invasive de l'invention comprennent un élément oscillant possédant une extrémité proximale et une sonde terminale. Habituellement, cette sonde terminale de l'élément oscillant comprend un matériau sensiblement non abrasif qui est conçu pour être en contact avec la surface d'un oeil sans entraîner une dégradation significative quelconque du tissu et présente une forme permettant d'épouser la surface de l'oeil au niveau de la région limbique. Des dispositifs comprennent aussi un mécanisme oscillant qui est connecté de manière opérationnelle à l'extrémité de proximale de cette pointe oscillante de sorte que lorsque le mécanisme oscillant fonctionne, cette pointe oscillante se déplace axialement sans dégrader les cellules de l'oeil. Des dispositifs d'abaissement de pression intraoculaire de la présente invention sont capables de transmettre de manière non invasive une force mécanique sur le tissu situé à proximité du tissu limbique.
