Abstract:
Apparatus include a particle array configured to propagate an incident solitary wave to an eye, a housing configured to support the particle array, and a sensor coupled to the particle array and configured to detect a return solitary wave propagating along the particle array from the eye. Methods include directing an incident solitary wave along a solitary wave particle array coupled to an eye and detecting a return solitary wave propagating along the solitary wave particle array from the eye. Methods also include estimating intraocular pressure for the eye by comparing solitary wave data to a relationship between a time of return solitary wave time of flight and an intraocular pressure.
