A doctor has recorded the tense moment he surgically implanted a platinum piece of jewellery into a patient’s eyeball.

Emil Chynn filmed himself performing the nail-biting procedure, which required the insertion of a 3mm-by-4mm-wide platinum heart into a patient’s eyeball, at Park Avenue LASEK Surgery, New York, USA.

The five-minute procedure is said to be rather pain-free and takes only three days to heal after the conjunctiva seals, reports the Story Trender. 

After three days the patient can’t feel the less-than 1mm thick jewel, as it is carefully smoothened, polished and curved to conform to the natural shape of the eye.

Dr Chynn firsts preps the patient by giving them a topical anesthetic and sterilizing the surface of the eyeball, lining a crosshair up to the part of the membrane the jewel is to be placed. 

With the crosshair in place, the doctor then cuts a small incision 3mm wide, which the jewel will slide into. 

The doctor, who has 20-years of experience under his belt, insists the jewel is almost impossible to have an allergic reaction to, as the body is able to accept this medical-grade of metal.

The surgery offers different shapes of jewellery, such as hearts and stars, and can also be removed through a procedure that last around five minutes.

Dr Chynn said: ‘This is a purely cosmetic surgery. There are only two or three people in the whole of the United States of America that have undergone this. 

‘It is not widely sought and I’m performing less than one surgery per year, out of a population of over 325 million.

‘Eye jewellery was developed in Holland over a decade ago and has been successfully implanted into hundreds of patients’ eyes in Europe without a single major complication or adverse event.’
