New contact lenses "can apply medication"

New contact lenses "can apply medication"

By Adrian Galbreth

Contact lenses said to be able to administer medications to the eye are being developed by a start-up in the US.

The technology is being worked on by Eyenovations, according to Technology Review.

A paper was already published in Investigative Opthalmology and Visual Science in January showing that the contact lenses were capable of releasing antibiotics for more than a month.

The technology began when Daniel Kohane of the Children"s Hospital in Boston joined with Joseph Ciolino of the Massachusetts Eye and Ear Infirmary to develop a hydrogel contact lens with a polymer film in which the medication is stored.

Changing the material could alter the rate at which the medication is released.

Eyenovations is now patenting its method of keeping medication administered for as long as 100 days.

Recently, Dr Ahmet Girgin spoke to the Asia-Pacific Academy of Opthalmology and the American Academy of Opthalmology about contact lenses which could help correct colour blindness.

OSN Super Site reported how coloured haploscopic lenses were found to make improvements for men who could not properly perceive colour.
