Doctors shocked after finding 27 contact lenses in woman's eye

British doctors have spoken of their shock after discovering an extraordinary 27 missing contact lenses in the eye of a woman while preparing her for a cataract operation.

Medical staff said they were startled by the rare find, with the 67-year-old patient said to have been oblivious to the "blueish mass" of lenses found in her eye.

She had reportedly been wearing monthly disposable lenses for the past 35 years but did not attend regular check-ups with optometrists.

The woman did not report any symptoms prior to arriving for surgery and thought discomfort caused by the lenses was due to dry eyes and old age.

It was only when she arrived for a pre-operative assessment that the discovery was made.

Details of the case, which occurred in November last year at Solihull Hospital, West Midlands, were recently outlined in the British Medical Journal (BMJ).

Specialist trainee ophthalmologist Rupal Morjaria said at first a mass of 17 contact lenses were found, before another 10 were discovered on further examination.

"None of us have ever seen this before," she told specialist magazine Optometry Today.

"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."

The patient, who has not been named, had her cataract surgery postponed following the discovery.

"Because she had harboured these contact lenses in her eye for an unknown length of time, if we had operated she would have had a lot of bacteria around her conjunctiva," Morjaria said.

"She was quite shocked. When she was seen two weeks after I removed the lenses she said her eyes felt a lot more comfortable. She thought her previous discomfort was just part of old age and dry eye."

Morjaria said she decided to make the case public to raise awareness of the importance of regular check-ups with optometrists.

"In this day and age, when it is so easy to purchase contact lenses online, people become lax about having regular check ups," she added.

"Contact lenses are used all the time, but if they are not appropriately monitored we see people with serious eye infections that can cause them to lose their sight."
