Electronic Speckle Pattern Interferometry (PulsESPI) technique to an animal
(bovine) cornea for the investigation of its dynamic behavior to localized
stresses is being presented. For the target of obtaining optimal results
from laser ophthalmic surgery for the correction of cornea, it has already
been observed that more attention is required on the adjustment of the
necessary ablative laser power, while taking into account the otherwise
neglected corneal elasticity as a parameter. It is being proposed that
this need can be fulfilled by analyzing through this technique the behaviour
of cornea under application of variable dynamic stresses. By addition
of elasticity to the related cornea mathematical model, corneal healing
evolution can also be forecasted for follow-up and for perfecting the
correction during the post-op period. The tests were complemented by an
in vitro measurement of the surface contour of the same cornea
using a Twymann-Green Interferometer.]]>Bally, G.V.,1979Drescher, J., W. Stork, S. Hey, A. Gundlach, K.D. Mueller-Glaser and C.F. Kreiner,1999Friedlander, M.H., M. Mulet, K. Buzard, N. Granet and P.
