Περίληψη:
In this work, ablation experiments of ex vivo porcine cornea tissue were
conducted with two solid state lasers ( an Er:YAG laser and the 4(th)
harmonic of an Nd:YAG laser, both in the ns pulse width range) emitting
in mid infrared and ultraviolet part of the spectrum respectively, at
moderate laser fluences. The cornea epithelium of each porcine eye was
manually removed before the ablation. Histology analysis of the
specimens was performed, in order to examine the microscopic appearance
of the ablated craters and the existence of any thermal or mechanical
damage caused by the mid-infrared and the UV laser irradiation. For a
detailed and complete examination of the morphology of the laser ablated
corneal tissue, the surface roughness was investigated by scanning
electron microscopy.
