Eye-Fi: Integrating optical data communication into intraocular lenses

The human eye is a compelling host site for wearable health-care electronics. Smart intraocular lenses can be used both to receive external optical data and to convey information to the user, along with monitoring ones health indicators and transmitting the results to a central unit. This is coined as Eye-Fi technology and can be deployed to a lens where commands to an embedded microelectronics chip are modulated either in a simple pattern of eye blinks, or in the light itself. In this paper, we demonstrate an integrated circuit meant to be implanted in an IOL, as a first stage to enable the lens to later perform intraocular health monitoring of the user.
