Abstract
A process and an apparatus for the surgical correction of ametropia, which can occur as a function of the corneal curvature in the optical system of one or both eyes of living beings, are proposed. The apparatus includes a grinder essentially comprising a base member to be fixed to the eye and a rotary-driven grinding or polishing punch. A displacement of the focal point in the retinal plane is achieved and consequently the ratio of the optical axis to the refractive force of the eye is corrected by grinding and/or polishing the cornea surface in the optical curvature region.
