Abstract

The present invention includes methods and devices for non-invasively delivering an active agent to the eye of a subject. In one aspect, for example, a device for delivering an active agent to an eye of a subject may include an ocular lens-shaped housing configured to contact a surface of the eye, and a reservoir coupled to the housing and configured to deliver an active agent to the eye, wherein the reservoir is located entirely within a 180 degree section of the housing. In another aspect, the reservoir is located entirely within a 150 degree section of the housing.

Claims

1. A device for delivering an active agent to an eye of a subject, comprising:

an ocular lens-shaped housing configured to contact a surface of the eye; and

a reservoir coupled to the housing and configured to deliver an active agent to the eye, wherein the reservoir is located entirely within a 180 degree section of the housing.

2. The device of claim 1, wherein the reservoir is located entirely within a 150 degree section of the housing.

3. The device of claim 1, wherein the reservoir further includes an electrode configured to provide an electrical current capable of iontophoresing an active agent.

4. The device of claim 1, further comprising a vacuum port coupled to the housing and configured to create negative pressure between the housing and the surface of the eye.

5. The device of claim 4, wherein the vacuum port is a vacuum bulb.

6. The device of claim 1, wherein the housing is configured in size and shape to allow the subject'"'"'s eyelids to close substantially thereover when positioned on the eye.

7. The device of claim 1, wherein the reservoir is a plurality of reservoirs located entirely within a 180 degree section of the housing.

8. The device of claim 7, wherein the plurality of reservoirs is configured in a side-by-side arrangement.

9. The device of claim 7, wherein the plurality of reservoirs is configured in a nested arrangement with respect to the center of the housing.

10. The device of claim 1, wherein a portion of the housing is configured to extended into a cul-de-sac under an eyelid of the eye of the subject such that electrical current flow is hindered between the eye and the eyelid.

11. The device of claim 1, wherein the housing is configured as a corneal lens.

12. The device of claim 1, wherein the housing is configured as a scleral lens.

13. The device of claim 12, wherein the housing is configured to position the reservoir in a lower cul-de-sac of the eye.

20. A method of iontophoretically delivering an active agent to an eye of a subject, comprising:

positioning the device of claim 1 on the surface of the eye of the subject; and

activating the device to deliver the active agent into the eye.

21. The method of claim 20, wherein positioning the device further includes applying negative pressure between the device and the eye.

14. A method for enhancing ocular delivery of an active agent to the eye of a subject, comprising:

contacting an ocular lens-shaped housing having a reservoir containing the active agent against an eye surface such that the reservoir contacts a delivery region of the eye, wherein said reservoir is located entirely within a 180 degree section of the housing; and

delivering the active agent from the reservoir into the eye while substantially maintaining alignment between the reservoir and the delivery region.

15. The method of claim 14, wherein substantially maintaining alignment further includes applying a vacuum between the housing and the eye surface sufficient to maintain the reservoir substantially in alignment with the delivery region during delivery of the active agent.

16. The method of claim 14, wherein substantially maintaining alignment further includes applying a tackifier between the housing and the eye surface sufficient to maintain the reservoir substantially in alignment with the delivery region during delivery of the active agent.

17. The method of claim 14, wherein delivering the active agent from the reservoir further includes actively delivering the active agent.

18. The method of claim 17, wherein actively delivering the active agent from the reservoir further includes iontophoretically delivering the active agent.

19. The method of claim 14, wherein delivering the active agent from the reservoir further includes passively delivering the active agent.

22. A device for delivering an active agent to an eye of a subject, comprising:

an ocular lens-shaped housing configured to contact a surface of the eye; and

a reservoir coupled to the housing and configured to deliver an active agent to the eye, wherein the reservoir surface area configured to face the eye is less than about 50% of the surface area of the housing configured to face the eye.

23. The device of claim 22, wherein the reservoir is a plurality of reservoirs.

24. The device of claim 23, wherein each of the plurality of reservoirs has a surface area configured to face the eye that is less than about 50% of the surface area of the housing configured to face the eye.

25. The device of claim 24, wherein the plurality of reservoirs is a plurality of annular reservoirs.
