Viewing chamber for preserving a corneal tissue. The cornea viewing chamber has a container and a lid. The container includes a corneal basket formed by a plurality of prongs for supporting the corneal tissue. The prongs are dimensioned such, that they accommodate corneas ranging in size from large to small. The lid has raised protrusions on its underside, which prevent the corneal tissue from being suctioned onto the lid. The protrusions also serve as a dimension gauge that indicates the size of the tissue stored in the container. Lid and container are threaded. A tapered plug in the lid, as well as the use of an O-ring, enhances the seal when lid is screwed onto the container, ensuring a leak-tight seal. The threaded connection has a thread-stop, to prevent over-torquing of the threaded connection.
