Worms mate in man's eyes, get plucked out right before larvae burst out

A 71-year-old man in South Korea had 11 living worms, identified as Thelazia callipaeda nematodes, removed from his eyes after experiencing discomfort, redness, and blurred vision for two months. The worms were found to be pregnant and had caused damage to the man's cornea. The worms' life cycle involves infecting animals' eyes through flies that feed on tears and secretions, and then migrating to a new host through the flies' mouthparts.
