Abstract
A device for the storage of a corneal specimen has means for the reception and entrapment of a corneal specimen, connected to the means for the creation of a pressure gradient with overpressure on the endothelial side and to the preservation medium circulation means in the layouts that present the means for the reception and entrapment of the cornea specimen. The means for the reception and entrapment of the corneal specimen entrap the sclera ciliary zone surrounding the cornea in an airtight manner to delimit a separate endothelial chamber and epithelial chamber in which the preservation medium can circulate with an overpressure in the endothelial chamber; The intermediate component and the endothelial lid comprise inlet and outlet orifices for the preservation medium which are connected to the means for the circulation of the preservation medium and the creation of a pressure gradient between the endothelial chamber and the epithelial chamber with overpressure in the endothelial chamber.
