“…Others modified this approach by placing the pressure sensor in an intraocular lens (IOL) for use with cataract surgery [13,14]. Wolbarsht et al [15] proposed another approach that used an elastic band placed at the globe's equator with an embedded pressure transducer to record changes in globe diameter. In 1996, McLaren et al [16] described the use of a subcutaneous telemetric pressure transducer with a catheter inserted into the anterior chamber in 7 unrestrained rabbits for up to 370 days.…”

Recent advances in microelectromechanical systems and nanoelectromechanical systems have enabled the development of 24-h intraocular pressure monitoring devices. Once these technologies have shown their safety and efficacy, larger questions as to the data interpretation and handling will arise. It is likely that the use of 24-h intraocular pressure monitoring will herald fundamental changes in our understanding and management of glaucoma.

“…Interindividual and intraindividual variation in central corneal thickness and rigidity, especially in patients with corneal abnormalities, could significantly affect the accuracy of measurements in the above-mentioned non-invasive approach 3 16 17. The claimed changes of corneal curvature are extremely small and of uncertain reproducibility.…”

With an ageing population showing an increasing prevalence of glaucoma, there is a pressing demand for continuous intraocular pressure (IOP) measurements which could surpass clinic-based measurements such as routine applanation tonometry. Glaucoma patients have fluctuations in IOP, and it has been proposed that these fluctuations are relevant to glaucoma progression. In addition, interindividual and intraindividual variation in corneal thickness and rigidity can lead to significant and poorly quantitated errors in applanation-based methods of estimating IOP. Microelectrical mechanical systems and complementary metal oxide semiconductor-based technology has enabled the development of smart miniaturised devices by augmenting the computational ability of microelectronics with capabilities of microsensors and microactuators. This review addresses various sensor technologies and both invasive and non-invasive approaches to the measurement of IOP. Advances in wireless communication (telemetry) between the implanted sensors and the external readout device are reviewed. In addition, biocompatibility of implantable sensors is discussed.

The purpose of this paper is the development of devices for monitoring the intraocular pressure (IOP) variations in a non-invasive way. The importance of the problem is caused by the need of a glaucoma diagnostic by control of the IOP in patients. It has been shown [1] that monitoring of the IOP variations over 24 h may change the glaucoma management of patients.Here we present a new prototype of an IOP sensing device based on a commercial hybrid contact lens (HCL) that provides a greater comfort for patients. Although the HCL was equipped with the same sensing BL film as in [2], in the sensing lens fabrication, a new design approach has been used. This approach allowed the use of different parts of the same BL film gauge as the pressure sensor and temperature effect compensator.
