She presented with left upper eyelid swelling and ptosis, or a droopy eyelid.
So, to all contact lens wearers out there, take our advice and maybe just check your eyes every now and then.
"I would like to reassure patients that contact lenses are safe when used appropriately", he added.
Enter a 42-year-old woman from the United Kingdom, who, since one long-ago day when she was 14, had a contact lens lodged under the lid of her left upper eyelid without even knowing it.
One mystery remains - doctors couldn't work out exactly why the patient's eye became inflamed when it did, after 28 years without trouble.
She stopped wearing lenses after the incident and went about her life like a normal person, and didn't think much more of it.
'However, it can be inferred that the lens migrated into the eyelid and resided there.
An MRI scan of the mystery lump revealed the existence of a cyst, so doctors made a decision to operate, according to a case study in the British Medical Journal released last week.
"During surgery, an encapsulated cyst was found". But the contact lens had lodged itself into her eyelid and stayed there for nearly thirty years.
Surgeons removed the lens, which was fully intact and preserved inside the eye tissue.
"This case report exhibits the longest time between traumatic RGP lens migration into the eyelid and presentation of eyelid swelling", said the authors of the case report. We can infer that the lens migrated into the patient's left upper eyelid at the time of trauma and had been in situ for 28 years'. Thankfully, her vision wasn't damaged.
