Abstract

When UV excimer laser radiation with energy density >200 mJ/cm2 falls onto the cornea, the surface is ablated away to a depth of 0.1-1 μm.1–3 The ablated material is ejected from the surface with supersonic velocities.4,5 The reactive forces of the suddenly accelerated ablated layer generate intensive acoustic shock waves. The effect of these acoustic waves on the bulbus is of great importance in excimer laser surgery.
