Long lasting eye-drops developed by scientists for symptoms of dry eye

Researchers from the University of Waterloo, Canada have developed eye drops for dry eye that only need to be applied once a week.

The drops can adhere to the eye’s surface for up to five days before being absorbed by the body, slowly delivering drug-infused nanoparticles to treat the symptoms of the condition.

Currently, the eye’s ability to self-cleanse washes away up 95% of dry eye drugs when delivered with traditional eye drops.
 
Dry eye can be caused by drugs like antihistamines and the contraceptive pill, as well as underlying conditions like Sjögren’s syndrome.
 
People can develop dry eye at any age, although it is more common in those over 50 and affects more women than men.
 
The research team is now focusing on preparing the drops for clinical trials with the hop that they could be available to patients within five years.
