Abstract

Apparatus for use with an external non-visible light source (24) is provided. The apparatus includes an intraocular device (60) configured for implantation in a human eye, and including an energy receiver (32). The energy receiver (32) is configured to receive light emitted from the external non-visible light source (24), and extract energy from the emitted light for powering the intraocular device (60). The intraocular device (60) is configured to regulate a parameter of operation of the intraocular device (60) based on a modulation of the light emitted by the external non-visible light source (24) and received by the energy receiver (32). Other embodiments are also described.
