| Abstract |
A basic factor with major influence on the outcome of the refractive surgery using
laser is the precise knowledge of the corneal hydration degree during the procedure.
To our knowledge, no successful and safe way to estimate «in vivo» the corneal
hydration during the procedure has been found until now.
The basic concept of this thesis, was the correlation of spectroscopic characteristics
of corneal related with the hydration. Besides the qualitative correlation we also
worked in the quantitative determination of hydration via experimental
measurements in two narrow spectroscopic regions in the near IR. Using
spectroscopic information obtained form 10 pork cornea samples and their
correlation to absolute hydration measurements (accurate dry and wet tissue weight
measurement) we achieved the absolute spectroscopic determination of the
hydration with a ~ 2.5% accuracy.
The thesis is organised as follows:
Initially certain basic elements of structure and hydration of corneal are presented
which will be studied spectroscopicaly. Then the basic principles of spectroscopy and
the elucidation of the operation of Fourier Transform Spectrometry are described.
Afterwards, the process that was developed at the samples is illustrated. The
qualitative and quantitative dependence of spectra of transmission by means of
reflection and absorption of cornea concerning the hydration in the near Infra red
region are analytically presented.
