Abstract: Provided is an inexpensive keratoconjunctival cover sheet that is comfortable and has good oxygen-permeability, contamination-resistance, wettability, handleability, and optical properties, and that can be used for medical treatment, visual correction, a cosmetic application, and the like. The keratoconjunctival cover sheet is constituted by a gel layer that includes metal ions and a water-soluble gelling agent exhibiting a gelation ability in the presence of the metal ions, and has a surface area capable of covering a cornea or keratoconjunctiva.
