Abstract

A method is provided for treatment of cataract in combination with a glaucoma procedure while maintaining the intraocular pressure by permitting aqueous to flow out of an anterior chamber of the eye through a surgically stented pathway. A trabecular stent is adapted for implantation within the trabecular meshwork of an eye such that intraocular liquid flows controllably from the anterior chamber of the eye to Schlemm'"'"'s canal, bypassing the trabecular meshwork. Depending upon the specific treatment contemplated, pharmaceuticals may be utilized in conjunction with the trabecular stent enabling post-cataract healing processes.

Claims

1. A method, of performing a combined surgery on an eye, comprising:

providing an opening into an anterior chamber of the eye;

extracting a cataract from the eye through the opening;

providing an ocular implant having an inflow portion in fluid communication with an outflow portion of the ocular implant;

transporting the ocular implant on a guide member through the anterior chamber of the eye to a uveal scleral outflow pathway of the eye;

moving the ocular implant relative to the guide member to position the ocular implant such that the inflow portion of the ocular implant is positioned in the anterior chamber and the outflow portion of the ocular implant is positioned in the uveal scleral outflow pathway; and

permitting aqueous humor to flow from the anterior chamber of the eye through the inflow portion of the ocular implant to the outflow portion of the ocular implant and into the uveal scleral outflow pathway of the eye.

2. The method of claim 1, wherein extracting the cataract is performed prior to positioning the ocular implant.

3. The method of claim 1, wherein positioning the ocular implant is performed prior to extracting the cataract.

4. The method of claim 1, wherein extracting the cataract comprises phacoemulsification of a lens of the eye.

5. The method of claim 1, wherein the combined surgery comprises lowering intraocular pressure of the eye.

6. The method of claim 5, wherein the lowering of intraocular pressure is a treatment for glaucoma.

7. The method of claim 1, wherein said ocular implant comprises a tube.

8. The method of claim 1, wherein said ocular implant comprises a cutting tip for making an incision in eye tissue.

9. The method of claim 1, wherein extracting the cataract comprises using an ultrasonic instrument.

10. The method of claim 1, wherein transporting the ocular implant comprises using an applicator.

11. The method of claim 10, wherein said applicator comprises an actuator to release said ocular implant from said applicator.

12. A method, of performing a combined surgery on an eye, comprising:

providing an opening into an anterior chamber of the eye;

extracting a cataract from the eye through the opening;

providing an ocular implant having an inflow portion in fluid communication with an outflow portion of the ocular implant;

transporting the ocular implant on a guide member through the anterior chamber of the eye to an aqueous collector channel of the eye;

moving the ocular implant relative to the guide member to position the ocular implant such that the inflow portion of the ocular implant is positioned in the anterior chamber and the outflow portion of the ocular implant is positioned in the aqueous collector channel; and

permitting aqueous humor to flow from the anterior chamber of the eye through the inflow portion of the ocular implant to the outflow portion of the ocular implant and into the aqueous collector channel of the eye.

13. The method of claim 12, wherein extracting the cataract is performed prior to positioning the ocular implant.

14. The method of claim 12, wherein positioning the ocular implant is performed prior to extracting the cataract.

15. The method of claim 12, wherein extracting the cataract comprises phacoemulsification of a lens of the eye.

16. The method of claim 12, wherein the combined surgery comprises lowering intraocular pressure of the eye.

17. The method of claim 16, wherein the lowering of intraocular pressure is a treatment for glaucoma.

18. The method of claim 12, wherein said method further comprises making an incision in trabecular meshwork of the eye for receiving said ocular implant.

19. The method of claim 12, wherein said ocular implant comprises a tube.

20. The method of claim 12, wherein said ocular implant comprises a cutting tip for making an incision in eye tissue.

21. The method of claim 12, wherein extracting the cataract comprises using an ultrasonic instrument.

22. The method of claim 12, wherein transporting the ocular implant comprises using an applicator.

23. The method of claim 22, wherein said applicator comprises an actuator to release said ocular implant from said applicator.
