  • Patent number: 6045563
    Abstract: An artificial chamber for a corneo-scleral disk for the purpose of taking a graft therefrom, the chamber comprising a stand, a cornea support carried by the stand, having a vertical axis, and possessing a head having a supporting top face into which there opens out at least one feed orifice, and a clamping ring for clamping the corneo-scleral disk on the cornea support. The clamping ring is fixed and carried by the stand, while the cornea support is mounted on the stand so as to slide along the vertical axis of the cornea support under drive from actuator means.

  • Patent number: 6007542
    Abstract: The present invention provides a device for folding a flexible intraocular implant and for keeping it folded, the device comprising two jaws, each jaw having an active surface forming a reentrant dihedral, and each being slidably mounted relative to the other jaw along a direction parallel to one of the faces of the reentrant dihedral, between a first position in which the jaws are in contact against each other via the ends of the faces parallel to the sliding direction, and at least one second position in which the jaws are moved apart from each other. At least one resilient member is coupled between the jaws and has the effect of tending to keep them in contact with each other. Each jaw is secured to a pushbutton situated facing its active surface and beyond the other jaw.
