摘要：
In order to remove impurities and contaminations adhering to the surfaces of an optical component, especially to the front and rear faces of a contact lens, electromagnetic radiation is caused to act on the optical component. Using that electromagnetic radiation, preferably the light of an excimer laser the wavelength, energy density and intensity of which are adjustable, the adherent impurities and any microorganisms present are killed, deactivated and removed photo-ablatively.
