An array of artificial adaptive intraocular lenses, the operating apparatus of which is based on binocular interaction and the accommodative convergence reflex of the eyes

Abstract

This invention relates to a series of adaptive artificial intraocular lenses, whose operating mechanism is based on the accommodative convergence reflex and which are characterized by requiring implantation in both eyes (bilateral pseudophakia). The new intraocular lenses are equipped with a biocompatible, non-cytotoxic material (a microchip with magnetic nanoparticles) that possesses electromagnetic properties. A conductor passing through the microchip forms a closed circuit. The variation in the distance between the artificial intraocular lenses during convergence and divergence movements of the eyes modifies the intensity and phase of the electromagnetic field between the microchips of both lenses, generating an electrical charge (voltage) at the ends of the conductor. This results in the flow of electric current through the closed circuit of the conductor due to the induced voltage and in accordance with the effect of electromagnetic induction.The range of artificial adaptive intraocular lenses is based on an electrical excitation device, and the change in the dioptric power of the intraocular lens during accommodative convergence of the eye is achieved either by increasing the refractive index of the lens, or by adjusting the shape of the intraocular lens.
