An implantable intraocular pressure sensor system has a sealed geometric shape with an internal pressure at a first value. The sealed geometric shape has a first light permitting surface and a second flexible surface. A pair of photocells is located in the sealed geometric shape. A light shield is coupled to the second flexible surface. When the second flexible surface is deflected, a light measurement by the pair of photocells indicates an intraocular pressure condition.

La présente invention concerne un système capteur de pression intraoculaire présentant une forme géométrique fermée, tarée à une première valeur de pression interne. La forme géométrique fermée comporte une première surface laissant passer la lumière et une seconde surface flexible. Une paire de cellules photovoltaïque est située dans la forme géométrique fermée. Un écran anti-lumière est couplé à la seconde surface flexible. Quand la seconde surface flexible subit une déflexion, une mesure de lumière effectuée par la paire de cellules photovoltaïques dénote un état de la pression intraoculaire.
