Intraocular femtoprojector
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.
1. An implantable intraocular device sized and configured to be implanted in a capsular bag of a wearer's eye, the implantable intraocular device comprising:
a femtoprojector comprising an electronics backplane including a driver circuitry, a frontplane of light emitting elements that produces an image, and projection optics comprising two opposing mirrors, wherein the femtoprojector is positioned to project images onto the wearer's retina when the intraocular device is implanted in the capsular bag of the wearer's eye;
a femtoimager that captures images of an interior of the wearer's eye;
a closed form haptic that positions the femtoprojector and femtoimager within the capsular bag;
a coil around a perimeter of the closed form haptic, the coil sized and configured for power transfer;
a flexible circuit board that is bendable to permit insertion of the intraocular device into the capsular bag;
electronic components including the femtoprojector, wherein the electronic components are mounted on the flexible circuit board,
wherein the intraocular device has a central clear aperture that permits light from an external environment to propagate through the intraocular device to the wearer's retina, and the femtoprojector and femtoimager are located outside the central clear aperture.
2. The intraocular device of claim 1 , wherein the flexible circuit board is bendable along creases between the electronic components.
3. The intraocular device of claim 1 , wherein the circuit board comprises two layers of circuit boards with the electronic components mounted on the two layers of circuit boards.
4. The intraocular device of claim 3 , wherein the two layers of circuit boards comprise a single flexible circuit board folded to form the two layers.
5. The intraocular device of claim 3 , wherein the femtoprojector is mounted on one of the layers and protrudes through the other layer.
6. The intraocular device of claim 1 , wherein the electronic components are suspended in a molding process.
7. The intraocular device of claim 1 , further comprising:
an optical lens in the central clear aperture.
8. The intraocular device of claim 1 wherein one or more of the electronics components are opaque and are located in the central clear aperture.
9. The intraocular device of claim 1 , wherein the electronic components receive data via through-body transmission through the wearer's body.
10. The intraocular device of claim 1 , further comprising:
a safety circuit to disable the femtoprojector.
11. The intraocular device of claim 1 , comprising at least two femtoprojectors.
12. The intraocular device of claim 11 , wherein at least two of the femtoprojectors are redundant.
13. The intraocular device of claim 11 , wherein at least two of the femtoprojectors are different from each other in at least one of spatial resolution, span of eccentricity and line of projection.
14. The intraocular device of claim 1 , further comprising:
a pressure sensor oriented to measure a pressure in an interior of the wearer's eye.
