Paper Abstract

The aim of the experiments is the development of a non-invasive technique for determining the location of an ultrasonic focus in the wall of the human eye. This would enable improvements in ultrasonic biometry and in ultrasonic tissue characterization in the eye. For the study, an eye model, consisting of an artificial cornea, a typical intraocular implant lens, and a thin polyethylene pellicle simulating the retinal membrane, was built. The model was irradiated in water by ultrasonic pulses from a medical A-mode transducer for biometry of the eye (single element, piston type, 8 MHz nominal center frequency, 1 kHz pulse repetition rate) and by a laser beam simultaneously. The results encourage further experiments.
