A collection of sterile devices designed to hold and deliver prepared donor endothelial tissue for transplantation into a recipient eye following the removal of Descemet's membrane and dysfunctional endothelium from the patient's cornea during ophthalmic surgery. It typically consists of a preparation base, a cartridge which holds the tissue in a double-coil preventing the surfaces/edges from folding and touching, and an introducer to manually position the cartridge from where the tissue is glided into the eye in correct orientation to unfold. This set is only used for partial replacement of dysfunctional corneal cell layers and not for total cornea replacement. This is a single-use device.
