Abstract

It was found that ablation at radiant exposures below 1 kJ/m ² both for polymethylmetacrylate (PMMA) and for the human cornea is minimal. Above 1 kJ/m ² the ablation rate increased approximately linearly with radiant exposure, the increase being twice as quick for cornea [0.26 (μm/pulse)/(kJ/m ²)] as for PMMA [0.13 (μm/pulse)/(kJ/m ²)]. Laminae of PMMA and human cornea of known thickness were ablated with nano second pulses at 213 nm. It is anticipated that the current data will serve as a basis for design of ablation procedures in the cornea.
