Abstract
A contact lens is disclosed, especially for the treatment of the frontal eye sections with a laser, the surface on the eye side of which has a radius adapted to the radius of curvature of the cornea, this contact lens exhibiting a reflective surface for enlarging the field of vision. The contact lens has the following features: the reflective surface is a planar area and is arranged in the part of the contact lens wherein the axial distance between the surface on the eye side and the frontal surface is at a maximum, the surfaces on the eye side and on the frontal side form an aplanatic system, the two surfaces almost penetrate each other on the side opposite to the reflective surface.

A contact lens for enabling treatment of frontal eye sections with a laser, the contact lens having a surface provided on the eye side with a radius adapted to the radius curvature of the cornea, a frontal surface of the contact lens being decentered with respect to the surface on the eye side, and a reflective surface inclined with respect to the ocular axis for enlarging the field of vision, the reflective surface being a planar area arranged in a part of the contact lens where the axial distance of the surface on the eye side and the frontal surface is at a maximum, the surface on the eye side and the frontal surface forming an aplanatic system, and the surface on the eye side and the frontal surface being disposed so as to almost intersect each other on a part of the contact lens opposite to the reflective surface.
