A misplaced contact lens was found after nearly 30 years and it turns out it never left.
According to a case study published in the British Medical Journal, a woman went to her doctor for a swollen eyelid. What started as a pea-sized lump grew over six months until it was visible on an MRI.
When doctors went to operate on the cyst, they were surprised to find a gas-permeable contact lens.
CNN reports the 42-year-old woman was hit in the eye by a shuttlecock while playing badminton when she was 14. She wore the rigid contact lenses at the time but assumed since the injury healed quickly that the lens had flown out.
She never used gas-permeable lenses after the incident, meaning the contact doctors removed had been embedded in her eyelid for 28 years.
Typical symptoms of a trapped contact lens include redness, acute pain and sensitivity to light.
