| laser |
Acronym for Light Amplification by Stimulated Emission of Radiation. In a laser, the oscillator (a gaseous, fluid or solid matter) is embedded in a resonator, usually consisting of two mirrors. Continuous energy supply leads to an occupation inversion of energy levels within the oscillator, meaning that more electrons are in an excited (higher energy) state than in the normal state. ...

| laser-assisted in situ keratomileusis |
Approved by the FDA for the correction of myopia, hyperopia and astigmatism. LASIK is a combination of two refractive technologies: Use of a microkeratome, to create a thin flap of tissue (approximately 130 to 180 microns thick) followed by excimer laser ablation to reshape the stromal tissue beneath the flap.
