Abstract
A wireless intraocular pressure monitoring device includes reflecting and detecting modules. The reflecting module includes a soft contact lens having a curvature corresponding to that of a cornea while worn. A metal layer is embedded in and deformable with the soft contact lens. The detecting module includes two waveguides, an oscillator, and a converting unit. The oscillator is operable to generate oscillation signals having a frequency dependent on an equivalent impedance of the waveguides such that the equivalent impedance corresponds to intraocular pressure. The converting unit is operable for receiving and converting the oscillation signals into an output signal corresponding to the intraocular pressure.
