Millions could be saved from going blind or needing eye surgery thanks to a sight-saving glue. The adhesive gel, developed by scientists, contains chemicals that when exposed to the light, seal cuts on the eye's surface. Researchers hope the glue, which would come in an eye drop, could stop the need for so many corneal transplants. About 4,000 cornea transplants are carried out each year in the UK alone, and around 117,000 in the US. An eye infection or trauma on the surface of the eye can cause scarring - leading to blurring or complete vision loss.
