The Excimer laser is a multi-wavelength laser that produces an invisible and cold ultraviolet light that, rather than cutting or burning, creates enough energy to separate tissue molecules. The ophthalmologist can shape and adjust the graduation of the cornea without damaging the surrounding eye tissues by applying it to it. The cornea tissue (stroma) is softly polished, slicing it till the cornea becomes a form of lens, as part of the Excimer laser therapy for a person to wave goodbye to their lenses. Vision is restored in this way by correcting refractive defects in a rapid, precise, dependable, and controlled way.
