  • Device for separating the epithelium layer from the surface of the cornea of an eye
    Patent number: 7708750
    Abstract: An automated mechanical device separates the epithelial layer of a cornea from the cornea. The device includes a separator such as a plate, wire or dull blade. The device can preserve a separated epithelial layer as a disk without rupturing the disk and without substantial epithelial cell loss. The epithelial layer is separated from the cornea without cutting the cornea.

  • Device for separating the epithelium layer from the surface of the cornea of an eye
    Patent number: 7004953
    Abstract: A device is disclosed for separating the epithelial layer of a cornea from the eye. The device includes a separator having an edge to remove the epithelial layer as the separator moves across the eye. The edge includes a thickness thicker than the thickness of at least one epithelial cell and less thick than the thickness of the epithelial layer. Separation can be performed mechanically, without the use of chemicals, so that the shape and integrity of the separated epithelial layer is preserved. The device can also be used with a polymer film that adheres to the epithelial layer to help preserve an integrity of the epithelial layer.
