ABSTRACT:
Apparatus for performing ultraviolet laser ablation of a surface, eg. an eye surface, including a laser delivery system (7) having a laser source (1) for generating a laser beam (2) and optics for applying the laser beam to the surface to be ablated, means (20, 20′) for providing a compatible liquid (32) in contact with the surface (4a) to be ablated, in a position whereby said laser beam (2) is applied to said surface through the liquid, wherein the laser beam is of a wavelength that substantially is not absorbed by the liquid.
