Abstract

Disclosed are devices and methods of treating an ocular disorder including forming a self-sealing incision in a cornea into an anterior chamber of an eye; introducing through the incision a fluid drainage tube having a distal end, a proximal end and a longitudinal, internal lumen extending through the fluid drainage tube, wherein at least the proximal end passes through the anterior chamber; and implanting the distal end of the fluid drainage tube in fluid communication with the suprachoroidal space such that the proximal end of the fluid drainage tube remains in fluid communication with the anterior chamber.

Claims

1. A method of treating disease in an eye, comprising:

introducing an ophthalmic implant into the anterior chamber of the eye, wherein the ophthalmic implant comprises an internal lumen through which aqueous humor can flow and wherein the ophthalmic implant is introduced into the anterior chamber in its entirety;

forming a passageway between the anterior chamber of the eye and the suprachoroidal space of the eye;

positioning the ophthalmic implant in the passageway between the anterior chamber and the suprachoroidal space such that the internal lumen of the ophthalmic implant provides fluid communication between the anterior chamber and the suprachoroidal space; and

delivering a substance and the ophthalmic implant into the eye through a common opening in the eye.

2. A method as in claim 1, further comprising causing at least a portion of the ophthalmic implant to expand while the ophthalmic implant is located in the eye, wherein the ophthalmic implant expands after the ophthalmic implant is positioned in communication with the suprachoroidal space.

3. A method as in claim 1, further comprising causing at least a portion of the ophthalmic implant to expand as the ophthalmic implant is introduced into the eye.

4. A method as in claim 1, wherein the internal lumen of the ophthalmic implant forms a first opening in a first end of the ophthalmic implant and a second opening in a second end of the ophthalmic implant and further comprising causing aqueous humor to flow from the anterior chamber into the suprachoroidal space through the internal lumen.

5. A method as in claim 1, wherein forming a passageway between the anterior chamber of the eye and the suprachoroidal space comprises performing a cyclodialysis.

6. A method as in claim 1, comprising forming a passageway between the anterior chamber of the eye and the suprachoroidal space and positioning the ophthalmic implant in the passageway after the passageway is formed.

7. A method as in claim 1, wherein introducing the ophthalmic implant into the anterior chamber of the eye in its entirety comprises passing a distal end and a proximal end of the ophthalmic implant through the cornea.

8. A method as in claim 1, further comprising performing a paracentesis with respect to the cornea and the anterior chamber of the eye.

9. A method as in claim 8, wherein the paracentesis is performed in the limbus.

10. A method as in claim 1, further comprising causing at least a portion of the ophthalmic implant to expand while the ophthalmic implant is located in the eye, wherein causing at least a portion of the ophthalmic implant to expand comprises causing the ophthalmic implant to unfold.

11. A method as in claim 1, wherein the ophthalmic implant expands to a shape that matches the curvature of the eye.

12. A method as in claim 11, wherein the ophthalmic implant expands to a shape that matches the curvature of the eye in the suprachoroidal space.

13. A method as in claim 1, wherein the ophthalmic implant comprises a fluid drainage tube.

14. A method as in claim 1, wherein positioning the ophthalmic implant comprises inserting a distal end of the ophthalmic implant in the suprachoroidal space.

15. A method as in claim 7, wherein passing the distal end and the proximal end of the ophthalmic implant through the cornea comprises sequentially passing the distal end and then the proximal end into the anterior chamber as the implant is being introduced.

16. A method as in claim 15, wherein the distal end and the proximal end of the ophthalmic implant are sequentially passed such that the distal end and proximal end are concurrently located within the anterior chamber.

17. The method of claim 1, wherein forming a passageway between the anterior chamber and the suprachoroidal space comprises separating at least a portion of the ciliary body from at least a portion of the sclera.

18. The method of claim 17, wherein separating at least a portion of the ciliary body from at least a portion of the sclera comprises detaching the portion of the ciliary body from the portion of the sclera.

19. The method of claim 1, wherein the implant is used to form the passageway.

20. The method of claim 1, wherein the substance comprises a viscoelastic substance.

21. The method of claim 20, wherein the substance is delivered into the eye and then the ophthalmic implant is delivered into the eye.
