Intraocular and extraocular devices

Abstract

Intraocular apparatus is provided that is shaped and sized to be implanted entirely in a subject's eye and configured for use with an extraocular imaging device. The intraocular apparatus includes an energy receiver configured to receive energy from outside the eye and to power the intraocular apparatus; a data receiver configured to receive image data from the extraocular imaging device; circuitry configured to process the data received by the data receiver into an image; an electronic display configured to emit light representing the image; and an eye-tracking sensor configured to sense a position of the subject's eye and to generate a signal in response thereto, the electronic display being configured to emit light representing a portion of the image corresponding to the position of the subject's eye sensed by the eye-tracking sensor. Other embodiments are also described.

         20 . Intraocular apparatus (i) shaped and sized to be implanted entirely in a subject's eye, and (ii) configured for use with an extraocular imaging device, the intraocular apparatus comprising:
 an energy receiver configured to receive energy from outside the eye and to power the intraocular apparatus;   a data receiver configured to receive image data from the extraocular imaging device;   circuitry configured to process the data received by the data receiver into an image;   an electronic display configured to emit light representing the image; and   an eye-tracking sensor configured to sense a position of the subject's eye and to generate a signal in response thereto, the electronic display being configured to emit light representing a portion of the image corresponding to the position of the subject's eye sensed by the eye-tracking sensor.   
     
     
         21 . The intraocular apparatus according to  claim 20 , wherein the circuitry is configured, in response to the signal generated by the eye-tracking sensor, to change the image captured by the extraocular imaging device such that the portion of the image corresponding to the position of the subject's eye, as sensed by the eye-tracking sensor, is displayed onto the electronic display. 
     
     
         22 . The intraocular apparatus according to  claim 20 , wherein the extraocular device is configured to change a view captured by the extraocular imaging device in response to the signal. 
     
     
         23 . An extraocular device for use with an intraocular apparatus configured to display an image onto a retina of a subject, the extraocular device comprising:
 a camera configured to capture the image; and   an eye-tracking sensor coupled to the camera and configured to sense a position of the subject's eye and to generate a signal in response thereto,   such that in response to the signal, the intraocular apparatus displays onto the retina a portion of the image corresponding to the position of the subject's eye as sensed by the eye-tracking sensor.   
     
     
         24 . A vision system comprising the extraocular device according to  claim 23 , wherein the vision system additionally comprises the intraocular apparatus, the intraocular apparatus comprising:
 an energy receiver configured to receive energy from outside the eye and to power the intraocular apparatus;   a data receiver configured to receive image data from the extraocular imaging device;   an electronic display configured to emit light representing the image; and   circuitry configured to process the data received by the data receiver into the image, and, in response to the signal generated by the eye-tracking sensor, to change the portion of the image that is displayed on the electronic display.   
     
     
         25 . The extraocular device according to  claim 23 , wherein the extraocular device is configured to change a view captured by the extraocular imaging device in response to the signal.
