During surgery on the human cornea using an UV laser, air saturated with water is flushed over the surface and immediately extracted to maintain the light transmission characteristics and the surface water content
For the working of optical surfaces with a water content, using an UV laser, it is flushed by air saturated with water and immediately extracted by suction. The air delivery is from a ring, with the optical material surface in its center, with a suction ring over it to extract the blown air. The geometry of the air inflow and outflow is structured to give a timed and stable rotary eddy to give a constant transmission of the laser light and maintenance of the optical material water content.
