Curing blindness by repairing corneas with invisible films

A patented treatment could restore eyesight for millions of sufferers of corneal disease.

The University of Melbourne-led team of researchers have grown corneal cells on a layer of film that can be implanted in the eye to help the cornea heal itself. They have successfully restored vision in animal trials and are aiming to move to human trials in 2017.

Birds, bees, robots and flying

He isn’t a pilot, but few people would know more about ways of navigating while flying than Prof Mandyam Srinivasan (Srini) of the Queensland Brain Institute. And he’s steadily finding out more.

Initially known for his work in bees, since receiving the Prime Minister’s Prize for Science in 2006, Srini has shown that birds and insects use a similar system of visual guidance to prevent themselves from crashing into trees when flying through dense forest.

Improved myopia treatment in sight

New glasses that slow the progression of short-sightedness or myopia are now available. The glasses which incorporate a novel lens design could potentially benefit some of the 3.6 million Australians with myopia and hundreds of millions of people worldwide.

Until now, correcting myopia has relied on measuring the clarity of vision at the very centre of the retina. Corrective lenses were designed to provide the wearer with clear central vision but did nothing for peripheral vision. Studies have now shown that short-sightedness progressively worsens in spite of correction using these traditional lenses.

From bionic ear to bionic eye

Melbourne scientists gave Australia the first practical bionic ear. Today, over 180,000 people hear with the help of the cochlear implant.

Now, The University of Melbourne is a key member in an Australian consortium developing an advanced bionic eye that will restore vision to people with severe vision loss. This device will enable unprecedented high resolution images to be seen by thousands of people with severely diminished sight, allowing them to read large print and recognise faces.
