Abstract

An electronic intraocular device is implantable into the capsular bag of a wearer's eye. In some cases, the intraocular device may include a femtoprojector. The femtoprojector projects images onto the wearer's retina when the electronic intraocular device is implanted in the wearer's eye. Different haptic designs may be used to keep the femtoprojector in position. In some embodiments, an imager is contained in a contact lens worn by the wearer. Images captured by the contact lens imager may be relayed to the intraocular femtoprojector. In some cases, the intraocular device may include an electronic capsular tension ring with a femtoimager. The femtoimager may capture images of the wearer's retina, for example for purposes of monitoring eye health.

Claims (21)

1. A system comprising:

an electronic scleral contact lens comprising a femtoimager, where the contact lens does not transmit sufficient oxygen to a cornea of a person with normal eyesight for the contact lens to be worn for more than two hours; and

an intraocular femtoprojector system in communication with the contact lens, wherein images captured by the femtoimager are projected by the intraocular femtoprojector.

2. The system of claim 1 where the contact lens comprises electronic components arranged in a way that would substantially obstruct the vision of a person with normal eyesight.

3. The system of claim 1 where the intraocular femtoprojector system comprises an ultra-dense light-emitting-diode array display.

4. The system of claim 1 where the intraocular femtoprojector system comprises a femtoprojector optical system comprising two curved mirrors.

5. The system of claim 1 where the intraocular femtoprojector system comprises a flexible peripheral portion containing a conductive coil.

6. The system of claim 1 where the contact lens is a colored contact lens.

7. The system of claim 1 where no electronic eye tracking influences images projected by the intraocular femtoprojector.

8. The system of claim 1 further comprising: glasses and/or an accessory device; where power is transmitted between any of the contact lens, the intraocular femtoprojector system, the glasses or the accessory device via magnetic induction, capacitive coupling, ultrasound, radio waves, infrared light or a through-body channel.

9. The system of claim 1 where data is transmitted between any of the contact lens, the intraocular femtoprojector system, glasses or an accessory device via magnetic induction, capacitive coupling, ultrasound, radio waves, infrared light or a through-body channel.

10. The system of claim 1 where the intraocular femtoprojector system includes more than one femtoprojector.

11. The system of claim 10 where different femtoprojectors project different colors.

12. The system of claim 10 where different femtoprojectors project images to different sections of the retina.

13. The system of claim 1 where the intraocular femtoprojector system is encapsulated in plastic comprising a curved surface that focuses projected images.

14. The system of claim 1 further comprising eyeglasses with an embedded high resolution camera; where the contact lens comprises eye tracking sensors, and eye tracking data generated by the contact lens select portions of a high resolution image captured by the high resolution camera embedded in the eyeglasses.

15. The system of claim 1 further comprising eyeglasses with an embedded high resolution camera; where the images captured by the femtoimager select portions of a high resolution image captured by the high resolution camera embedded in the eyeglasses.

16. A system comprising:

an electronic scleral contact lens comprising a femtoimager; and

an intraocular femtoprojector system in communication with the contact lens, wherein images captured by the femtoimager are projected by the intraocular femtoprojector; and

eyeglasses with an embedded high resolution camera; where the contact lens comprises eye tracking sensors, and eye tracking data generated by the contact lens select portions of a high resolution image captured by the high resolution camera embedded in the eyeglasses.
