Doctors Sew 47-Year-Old Emma Marsden's Eyelid Shut After Parasite Perforates Cornea

Summary

  • Four days after falling face-first into mud and water while wearing contact lenses, Emma Marsden developed intense pain that later became complete vision loss in her right eye.
  • Doctors said the key mistake was waiting until evening to remove the lenses, allowing Acanthamoeba—a parasite found in tap water, soil and dust—to infect and erode her cornea.
  • The infection grew so severe that surgeons sewed her eyelid shut after the cornea perforated, and she now needs eye drops every two hours plus weekly checkups.
  • A corneal transplant is expected but has been pushed back for years because of the infection, turning her case into a warning to keep contact lenses away from water.
