SHEFFIELD University engineers have developed a new technique using stem cell therapy which they hope will help the natural repair of eyes damaged by accident or disease.

Their research could help millions of people across the world retain – or even regain – their sight.

The team have created a new method for producing membranes to help in the grafting of stem cells onto the eye, mimicking structural features of the eye itself.

The technology has been designed to treat damage to the cornea, the transparent layer on the front of the eye, which is one of the major causes of blindness in the world.

Treating corneal blindness is a particularly pressing problem in the developing world, where there are high instances of chemical or accidental damage to the eye.
