Dynamic Corneal Imaging, DCI is a new procedure, which was developed in the last seven years in co-operation of
the Landesaugenklinik Salzburg and the Institut für Allgemeine Physik of the TU Wien. The mechanical
characteristics of the human cornea can be shown in vivo and local (and topographic relevant) factors can be
considered. The principles are based on:
i) the Computer Assisted Video-Keratography (CAVK) by the Placido-method,
ii) a controlled indentation of the cornea (central and peripheral) with the help of electronic controlled micro-
motors,
iii) an electronic registration of the time of contact of the probe and simultaneous control of position and phase of
pulse of the patient,
iv) a sequential registration of images during pre-selected indentation-steps, and
v) an analysis of the different CAVK-indentation-images.
Aim of the planned study is: An improvement of the method of DCI, development of standard-curves in normal
probands, analysis of different corneal diseases (Keratoconus, Dystrophia pellucida marginalis, scars after keratitis
herpetica, partial perforating and lamellar keratoplasty or perforating injuries), study of DCI-data before ad after
refractive surgery and valuation of new analysing-methods of DCI-data.
