The minuscule stint being used by surgeons at the Western Eye Hospital

Medics at a specialist eye hospital have pioneered the smallest device that has ever been implanted into the human body.

The snorkel-like iStent is just 0.33mm and is being used to lower eye pressure among sufferers of glaucoma being treated at the Western Eye Hospital.

Consultant ophthalmic surgeons and glaucoma specialists at the Marylebone hospital, Faisal Ahmed, Laura Crawley and Professor Philip Bloom have been implanting the device for over a year with positive results.

Weighing just 60mg, it is implanted at the end of cataract surgery and placed inside the eye to encourage the fluid within the eyeball to drain more effectively.
