Abstract
This study was designed to perform multifrequency impedance measuremen ts on the pig's eye. On one hand, impedance of the ocular tissues was measured from 10 kHz to 10 MHz. The aqueous and vitreous humours and t he cornea showed no relaxation in this range of frequencies, whereas t he lens and its parts (the cortex and the nucleus) did. On the other h and, multifrequency EIT and dynamic imaging were performed on the lens and on the whole eye. Data and images obtained after thermal and chem ical injuries are presented and discussed.
