IOP analysis of the MCL. a Schematic of the experimental set-up for IOP sensing. A syringe pump controlled the pressure in the eye. The reading coil is placed parallel on the top of the MCL. b Photographs of the mydriasis process in the rabbit eyeball. Scale bar, 1 cm. c Photographs of the IOP test process on rabbit eye. The injection of physiological saline to control intraocular pressure (left), the wearing of contact lens (middle), and wireless monitoring (right). d Reflection coefficients at an intraocular pressure of 6.0 mm Hg after wearing MCL on an eye of a rabbit in vivo. e Wireless recording of the reflection coefficients under different pressures (6.0–60.0 mmHg) in the frequency range of 200 to 230 MHz. f The frequency response of MCL worn on the rabbit’s eyes at a pressure between 6 mm Hg and 60 mm Hg
