Abstract: An illuminated contact lens system for illuminating an interior of a patient's eye includes a contact lens, an external light source, and a light engine. The lens refracts directed light into the eye. The light source emits the directed light toward the eye. The light engine transmits electronic control signals that cause the light source to emit the directed light. A prism array connected to an annular tube containing the light source may optionally shape the directed light into a conical distribution pattern. A control board may drive the light source in response to the electronic control signals, and may be optionally used as a proximity sensor. A method includes receiving the electronic control signals from the light engine via the control board, illuminating the light source, and emitting the directed light from the toward the eye.

Abstract: An instrument to facilitate hands-free illumination of an eye for a surgical procedure. The instrument includes an optical end of unique architecture and surfacing such that the instrument may be left immobile while sufficiently illuminating an eye interior with greater than 100° of wide beam spread angle provided. Further, the grind surfacing provided to the end cone of the optical end provides enhanced light distribution.
