Application of RFID technology to intraocular
instrumentation requires an understanding of the
reliability of propagation through optical tissues and
fluids. In this study, the working distance for passive
RFID operation is measured in a simulated intraocular
environment using porcine eyes. Results are obtained in
three common RFID ranges: low frequency, high
frequency and ultra-high frequency. Several media were
tested to assess the possible impact of intraocular
materials. Variations in the possible working distance
were observed for certain media, but the data suggest that
reliable RFID operation for intraocular sensors is possible
at a range of 2-4 cm.
