A method for effecting controlled refractive correction of the cornea comprising a contact lens whose concave surface is wetted with an inert ultraviolet absorbent liquid. An excimer laser feeds a cylindrical bundle of quartz fibers terminating angularly in a decollimating matrix at the contact lens in such manner as to attenuate the ultraviolet flux in said liquid proportional to the depth thereof at the cornea so as to effect greatest corneal ablation at the thinnest depth of the liquid.
