II. Management: Displaced Contact Lens

  1. Reassurance that lens will not travel retrobulbar
  2. Find the lens
    1. Have patient look up or down as lids are held
  3. Move off Cornea to Sclera
  4. Remove the lens with irrigation or with plunger
  5. Replace the lens on the Cornea
  6. Fluorescein will stain lens permanently but may ease finding it
