摘要：
Preservation device (1) of a corneal sample (3) comprising means for receiving and clamping the corneal sample (3), subject to means creating a pressure gradient with overpressure by the endothelial side and means circulating a liquid preservation provisions which have receiving means and clamping of the corneal sample (3), in which device: - the receiving means includes a first part, called intermediate part (2), comprises a hole (6a) of the diameter of the cornea (3a) surrounded by a circular groove (6b) and a flange (6c) defining a housing for receiving the corneal sample (3), said housing ensures correct centering corneal sample (3) in its installation on the device and allows said corneal sample remains stable in the opening of the device in the operating room - the means of clamping includes a second part, called endothelial cover (4) comprising a hole (10a) the diameter of the cornea (3a) surrounded by a flange (10b) for passing clamping the corneal sample ( 3) crushing the sclera collar (3b) on circular groove (6b) of the intermediate part - the device includes a third part, called epithelial cover (5) - the receiving means and clamping of the corneal sample (3) is adapted to imprison sealing collar sclera (3b) surrounding the cornea (3a) to define an endothelial chamber (18) and an epithelial chamber (19) separated, by which can circulate preservation medium with an overpressure within endothelial chamber (18) - endothelial chamber (18) is constituted by a certain space between endothelial cover (4) and the intermediate part (2), after sealing engagement of said cap with said part Endothelial - epithelial chamber (19) is constituted by a certain space between the intermediate portion and the epithelial cover (5), after engagement of said epithelial cover (5) with said workpiece (2) - the intermediate part (2) and endothelial cover (4) comprise inlet ports (7a, 11a) and outlet (7b, 11b) preservation medium, with which are connected the means for circulating
