A 42-year-old woman in the United Kingdom got nailed in the eye playing badminton as a teenager, and lost one of her contact lenses. No big deal, right?
According to CBS News, doctors discovered the missing lens embedded in a cyst in her left eyelid.
It's not like the woman was looking for it the entire time, though.
An MRI revealed a tiny cyst just above her eye, which doctors removed. When doctors tried to remove the the cyst, it broke open and revealed an extremely fragile hard contact lens inside.
Two brain scans (one from the top of the woman's head, and one from the side) showing the small cyst in her eyelid.
Nearly 30 years after the fact, the woman couldn't recall how the lens got there or how long it had been there.
Initially, the 42-year-old woman could not remember how the contact lens could have remain lodged in her eye - until her mother reminded her of the badminton incident.
The doctors who treated the woman said they could "infer that the [contact] lens migrated into the patient's left upper eyelid at the time of trauma and [remained there] for the last 28 years", they wrote in the report. According to CBS, after the patient lost her contact lens, she never wore them again.
The doctors could not come to a conclusion on why it had taken almost three decades for the embedded contact lens to cause swelling or discomfort. The doctors assume that this drooping was due to the embedded contact lens, they wrote.
