Eccentric Graft

Eccentric Penetrating Keratoplasty 

  • Can be seen:
    • After rotating autokeratoplasty, which was performed when a small corneal scar impinges on the center of cornea but the rest of the cornea is normal.
    • Eccentric trephine cut may be done when significant corneal scar or opacity extends towards one side of the corneal periphery to avoid an excessively large graft.
  • Disadvantages: quality of optical result usually less than normal centered graft.
