Why laser is a real eye-opener

Efforts to correct short sight by reshaping 바카라사이트 cornea using laser surgery have received a boost at Imperial College, London, where a new infra-red laser has been developed which is more compact and cheaper to use than anything produced to date.

The brainchild of Chris Phillips, senior lecturer in physics, and Russian physicist Kostya Vodopyanov, 바카라사이트 laser has cost Pounds 300,000 and taken five years to create. It is expected to be developed commercially by a United States company.

The Russians have been experimenting with eye surgery for impaired vision since 바카라사이트 1970s. The aim has been to find equipment which is highly accurate and does not cause too much damage.

"You need a wave length where 바카라사이트 laser radiation is absorbed at a very thin depth in 바카라사이트 tissue," says Dr Phillips. So thin is 바카라사이트 absorption of his laser by 바카라사이트 corneal tissue that, if you put your hand in front of it, it will burn a little hole in your hand, but you will not be able to feel 바카라사이트 hole.

Asked why 바카라사이트 innovation had not gone to a British company, David Thomas, pro-rector of research contracts at Imperial College, said: "There's no UK company that is in this sort of laser business. It's a pity, but 바카라사이트re it is."
