Abstract

Electronic contact lenses (ECL) are a high-tech solution for diagnosing, including early, both ophthalmic and systemic diseases. The authors of the article propose the implementation of 3P medicine approaches by integrating electrodes and circuits into the ECL to realize bioelectrical impedance spectroscopy (BIS) of the anterior eye. This helps to analyze the blood circulation parameters of this part of the eye. Electrode lead system modeling integrated into the contact lens was carried out by using the finite element method. It was obtained for the correct operation, the presence of an electrically insulating layer between the biological tissues of the eye and the main material of the contact lens is necessary. The electrode diameter is 0.8 mm, and the optimal distance between the current electrodes should be 6 mm, between the potential – 4 mm. Assessment of the power level required for BIS shows the possibility of technical implementation of this methodology from an energy point of view.
