Methods and systems for diagnosing and treating eyes using laser therapy
Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.
1. A wearable augmented reality device comprising:
an augmented reality head-mounted ophthalmic system comprising an augmented reality display platform comprising:
a frame configured to be worn on the head of a wearer wearing the head-mounted system; and
a display attached to the frame, the display comprising;
a waveguide stack configured to pass light from the world into an eye of the wearer; and
a light source configured to provide light for generating virtual content,
wherein the waveguide stack comprises a plurality of waveguides, each waveguide of the plurality of waveguides comprising:
in-coupling diffractive optical elements configured to in-couple light provided by the light source, and
out-coupling diffractive optical elements configured to out-couple in-coupled light to the eye of the wearer,
wherein one or more waveguides of the plurality of waveguides are configured to output in-coupled light to an eye of the wearer with a different amount of wavefront divergence than one or more other waveguides of the plurality of waveguides, wherein different amounts of wavefront divergence are associated with different accommodation by the eye, wherein the outputted light with different amounts of wavefront divergence forms virtual objects at different perceived depths away from the wearer, and wherein each waveguide of the plurality of waveguides is configured to guide light therein by total internal reflection between opposing surfaces of the waveguide;
a laser configured to administer laser therapy to the eye of the wearer; and
an adaptable optics element configured to direct the light outputted from the waveguide stack to project an image to a particular portion of the wearer's eye.
2. The device of claim 1 , wherein the laser is mounted to the frame.
3. The device of claim 1 , wherein the augmented reality head-mounted ophthalmic system is configured to display the image to the wearer as part of the laser therapy.
4. The device of claim 3 , wherein the augmented reality head-mounted ophthalmic system is configured to orient the eye of the wearer in a desired direction during exposing the wearer to light from the laser, wherein the augmented reality head-mounted ophthalmic system is configured to orient the eye by displaying an object for the eye of the wearer to focus on.
5. The device of claim 3 , wherein the augmented reality head-mounted ophthalmic system is configured to display a moving object as part of the laser therapy.
6. The device of claim 1 , wherein the augmented reality head-mounted ophthalmic system is configured to provide instructions to the wearer before exposing the wearer to light from the laser.
7. The device of claim 6 , wherein the augmented reality head-mounted ophthalmic system is configured to provide instructions to the wearer after exposing the wearer to light from the laser.
8. The device of claim 6 , wherein the instructions comprise one or more of shutting the eyelids for a set duration and blinking a set number of times.
9. The device of claim 1 , wherein the device is configured to direct laser light to the eye at an intensity, wavelength, and duration to alter eye tissue.
10. The device of claim 1 , wherein the laser is configured to reduce a growth of abnormal blood vessels or to close abnormal blood vessels.
11. The device of claim 10 , wherein the laser is configured to perform full laser photocoagulation.
12. The device of claim 10 , wherein the laser is configured to treat wet age-related macular degeneration.
13. The device of claim 1 , further comprising a delivery system configured to inject a photosensitizer into the eye, the laser configured to activate the photo sensitizer.
14. The device of claim 1 , wherein the wearable augmented reality device is configured to determine an area for exposure to light from the laser.
15. The device of claim 14 , wherein the wearable augmented reality device is configured to determine the area for exposure by imaging a retina and surrounding tissue of the eye and determining a presence of choroidal neurovascularization.
16. The device of claim 1 , wherein the adaptable optics element comprises a variable focus element.
17. The device of claim 1 , wherein the variable focus element comprises a membrane mirror.
18. The device of claim 17 , further comprising:
one or more electrodes coupled to the membrane mirror; and
a control system configured to selectively control the one or more electrodes to modify a shape of the membrane mirror.
19. The device of claim 1 , wherein the display platform comprises a fiber scanning display.
