Abstract
The present invention relates to a device for holding human or animal corneal tissue previously removed for photon treatment thereof with electromagnetic radiation, notable in that the holding device comprises: a stack of elements along a longitudinal axis (A-A′) of the device, said stack comprising: a first plate (1) that is transparent to the electromagnetic radiation, a peripheral seal (4) positioned on the first plate (1), the peripheral seal (4) being intended to extend around the corneal tissue (6), a second plate (2) that is transparent to the electromagnetic radiation on the peripheral seal (4), an immobilizing system (51, 52) for immobilizing the stack of elements and able to press the first and second plates (1, 2) firmly against the corneal tissue in order to apply mechanical stress to the anterior and posterior faces of the corneal tissue.
