This article mainly discusses the theoretical derivation and the estimate of the intraocular pressure (IOP) sensor by using inductance. The inductance changes associate with the variation of anterior corneal curvature radius due to the differences of IOP. The value of inductance is transformed by the LC oscillator, and the signal is transmitted by antenna, and finally read by the exterior readout circuit to achieve IOP measuring. The result show that the estimative values of inductance is close to the measured values, and the percentage of inductance variation is about 0.08% per 1 mmHg. Because of the low percentage, it makes much harder to realize readout circuit. In the future, the alteration of structure and material are considered to increase the percentage of varying inductance.
