She thought she just had dry-eye syndrome. Instead, she had 27 contact lenses stacked up in one eye!

A 67-year-old British woman went to the doctor with eye discomfort. She was scheduled for cataract surgery. But when she returned for a pre-operative assessment, doctors made an amazing discovery, Optometry Today reports.

A “blueish mass” of 17 contact lenses has been discovered in the eye of a patient who was scheduled for cataract surgery.

The 67-year-old patient was unaware that the contact lenses were missing, and later told surgeons that she thought her discomfort was due to dry eye and old age.

Specialist trainee ophthalmologist, Rupal Morjaria, told OT that another 10 individual contact lenses were discovered in the woman’s eye following further examination at Solihull Hospital.

The operating team, which included an ophthalmologist with more than 20 years of experience, were startled by the discovery, Ms Morjaria explained.

“None of us have ever seen this before,” she added.

“It was such a large mass. All the 17 contact lenses were stuck together. We were really surprised that the patient didn’t notice it because it would cause quite a lot of irritation while it was sitting there,” Ms Morjaria elaborated.

The case was published this month in the British Medical Journal. Optometry Today reported that the woman had been wearing contact lenses for 35 years and thought her discomfort was caused by "old age and dry eyes."

“She was quite shocked,” Morjaria told OT. “When she was seen two weeks after I removed the lenses she said her eyes felt a lot more comfortable.”
