<p>1. Contact lens (1) for observation and treatment by a beam of coherent radiation of a working point (T) situated in an eye (3) on the optical axis (6) of the lens (1), such contact lens (1) comprising a spherical entry surface (8) having a real Weierstrass point (A') and a virtual Weierstrass point (A) both situated on the optical axis (6), a contact surface intended to be applied to the cornea (2) of the eye (3) and a body situated between the entry surface (8) and the contact surface, the optical centers of said surfaces both being situated on said optical axis (6) characterized in that the radius of curvature (Re) of the entry surface (8) has a value such that the body of the lens, the contact surface and the parts of the eye (3) traversed by said beam together form an image of the real Weierstrass point (A') situated at the location of the working point (T).</p> |
