1. Apparatus for medical treatment, comprising:
a laser source, which is configured to output a treatment beam of laser radiation;
an aiming beam source, which is configured to output an aiming beam of visible radiation in alignment with the treatment beam and having smaller intensity than the treatment beam;
an optical device, which is configured to direct the aiming beam to impinge on a limbus of an eye and, after alignment of the aiming beam with the limbus, to direct the laser radiation to impinge on the limbus of the eye with optical properties chosen so as to apply a desired treatment to a tissue structure associated with a cornea of the eye within the limbus; and
a marker utility for marking a point onto which the eye should be focused during the treatment by providing a light spot in a central region of the optical device in front of the eye while the aiming beam and the treatment beam are directed to the limbus.
