The present invention relates to an adaptor of a laser for use in vision correction surgery that forms a laser beam non-irradiated region, of which an upper portion is coaxially aligned with an object lens of the laser, and a lower portion is coaxially aligned with a cornea of a patient, in order to set a position of the cornea of the patient with respect to the object lens of the laser. A pair of spaced shields for blocking the laser beam is provided on a non-refraction lens or refraction lens which is installed in the adaptor, the laser beam of the laser going through the non-refraction lens or refraction lens
