United Kingdom-based Solihull Hospital medical staff found 27 missing contact lenses in the eye of a patient seeking cataract surgery, according to CNN.
Here are four things to know:
1. A consultant anesthetist found the contacts when numbing the patient's eye.
2. Of the 27 lenses, 17 were stuck together by mucus and another 10 were loose in the eye.
3. It is unclear how long the contacts were clustered in the patient's eye. The patient told surgeons sometimes she could not find a contact when she tried to remove it. Therefore, she thought she had dropped the contact.
4. Thomas Steinemann, MD, American Academy of Ophthalmology clinical spokesperson, said although he is aware of patients having a single lens stuck in an eye, having 27 is unprecedented. He told CNN, "This is one for the record books, as far as I could tell."
