This is an artificial tear duct made of Pyrex glass that remains in place permanently. This operation is usually performed under general anaesthesia, although it can be performed under local anaesthesia with intravenous sedation by an anaesthetist for patients unfit for general anaesthesia.
A Jones tube can be used when DCR surgery has failed and for patients who have a blockage of the duct between the eye socket and nose caused by scars, recurrent infections or ageing.
