The Excimer laser is a form of ultraviolet chemical laser, and is the key element that has made laser eye surgery possible. Though Excimer laser was originally used in semiconductor manufacturing in the 1970s, its use in eye surgery is now fairly widespread. While working at the IBM research laboratories in 1982, Dr. Rangaswamy Srinivasin and his research team discovered the potential of the Excimer laser in interacting with biological tissue. An ophthalmologist, Dr. Steven Trokel, explained its connection with the corneal tissue. And this was how LASIK eye surgery came into existence.
There are several types of lasers, but excimer is the preferred choice when it comes to corrective eye surgery. This is due to the fact that excimer is the most technologically advanced laser type. The excimer laser is, literally, a cool laser. That is, it precisely removes the desired part of the corneal tissue, without heating up or damaging the adjacent tissue. Quite amazingly, the excimer laser is so precise that it is capable of removing 0.5% of a human hairs width at a time. That fact itself is enough for patients to believe that excimer-assisted eye surgery is not a gimmick, but a...
