  • Publication number: 20190374332
    Abstract: Systems and methods for implanting scaffolds in a corneal pocket of a cornea are provided. In some embodiments, a reversibly deformable scaffold may have a relaxed state and a deformed state. The scaffold may include a first ring and a second ring, a first connector extending from the first ring to the second ring, and a second connector extending from the first ring to the second ring. In some embodiments, a curvature of the first connector and a curvature of the second connector may extend at least partially radially outwardly relative to a central axis of the first ring and the second ring.

  • Publication number: 20150257873
    Abstract: An artificial cornea is formed from a hydro gel polymer and includes a monolithic body having a center optic surrounded by an annular rim. Artificial cornea is inserted into a central anterior opening in a cornea so that the annular rim enters an annular pocket surrounding the opening. The height of the center optic matches the depth of the central opening so that the level of the artificial cornea matches that of the native cornea.
