Summary:Spiral resonator corneal contact lenses for continuous intraocular pressure (IOP) are promising devices for the diagnosis of glaucoma. Here, we design a spiral resonator corneal contact lens with high sensitivity and simplify the fabrication process. A method for manufacturing 3D spiral microfluidic channels in corneal contact lenses is proposed. The use of liquid metal improves the sensitivity of spiral resonators and does not affect the deformation of the lens. The performance of the device is evaluated using an artificial silicone eye. The sensitivity of the sensor reached 0.2557 \text{MHz}/\upmu\mathrm{L} and the results proved its good stability and repeatability. The results show its great potential for clinical application.
