Claim 0:
1. An auxiliary optic system for use outside of a visualization device the visualization device being suitable for observing eye elements during surgery along an optical axis, the auxiliary optic system comprising:
optic devices aimed at affecting visualization of the eye elements by the visualization device by:
selecting a wave-length spectrum of light of between about 420 to about 750 nanometers to be emitted towards the eye from a light source of the auxiliary optic system along a light path; and
changing an optical power by which the light emitted towards the eye from the light source along the light path converges;

wherein the auxiliary optic system comprises a beam splitter intercepting the optical axis-X of the visualization device for reflecting at least part of the light emitted by its light source to extend coaxially along the optical axis of the visualization device towards the eye;
wherein the changing of the optical power is by introducing a lens into the light path before it reaches the beam splitter from the light source, and
wherein the interception of the optical axis of the visualization device is along a section of the optical axis between the objective lens of the visualization device and the eye being observed.
