INTRAOCULAR DEVICE FOR THE RESTORATION OF ACCOMMODATION OF THE EYE AFFECTED BY PRESBYOPIA

摘要

from toss of tension of the wnular fibers caused by increase in the ten diwmtcr, said device being designed to be surgically implanted in the ciliary salcus, behind the iris, and configured to compensate die loss of tension of me zonular fibers by exerting on the ciliary sufcns a pressure tending to increase its diameter. The invention is characterized in that the device comprises a dosed tubular envelope (1) made of an elastic and fluid-impermeabl material, the envelope (1) being shaped like a ring or a ring portion having a predetermined outer diameter (20) at rest, the inner ring wall (11) of the envelope (I) delimiting a lumen (12) adapted to be filled with an incompressible fluid tending to increase the outer diameter (20) up to a value whereby the loss of tension of the zonular fibers is compensated.
