Optometrist Monika Marczak, of McMurray, Pa., found this contact lens that was “lost” under a patient’s lid for two and a half months. The patient hadn’t complained of any foreign body sensation, photophobia or decreased vision. But she did report mucus discharge the night before and a slight swelling of the top lid. 

“Once I stained the eye with a fluorescein sodium strip and inverted the top lid, there was a thick layer of mucus deep in the upper fornix,” Dr. Marczak says. “I removed the strand of mucus with jeweler’s forceps, and only then was I able to see there was a contact lens that was even deeper within the fornix.”
