Abstract

Methods of implanting an intraocular pressure sensor and systems tbr sensing intraocular pressure are disclosed. An intraocular pressure sensor, including, a top surface, may be placed through the sclera of an eye of a patient. The intraocular pressure sensor may be caused to be inserted into the sclera until the top surface of the intraocular pressure sensor is substantially flush with the exterior wall of the sclera. An implantation wand may be used to assist in the insertion process. The wand may be disengaged from the tntraocuiar pressure sensor after it has been implanted.

Claims

1. A method of implanting an intraocular pressure sensor, the method comprising:

placing an intraocular pressure sensor through the sclera of an eye of a patient, wherein the intraocular pressure sensor comprises a top surface; and

causing the intraocular pressure sensor to be inserted into the sclera until the top surface of the intraocular pressure sensor is substantially flush with the exterior wall of the sclera.

2. The method of claim 1 wherein the intraocular pressure sensor further comprises a coil disposed underneath the top surface, and wherein causing, the intraocular pressure sensor to be inserted comprises rotating the intraocular pressure sensor in a direction that causes the coil to pass through the sclera.

3. The method of claim 2 wherein the coil comprises a tapered tip configured to engage with tissue of the eye and substantially prevent the intraocular pressure sensor from being withdrawn from the eye after the intraocular pressure sensor has been inserted in the eye.

4. The method of claim 1 further comprising:

determining an insertion location on the sclera at which the intraocular pressure sensor is placed for insertion.

5. The method of claim 4 wherein the insertion location for a pseudophakic eye is approximately 3.5 millimeters from the limbus.

6. The method of claim 4 wherein the insertion location for a phakic eye is approximately 4 millimeters from the limbus.

7. The method of claim 1 wherein the intraocular pressure sensor further comprises a screw disposed underneath the top surface, and wherein causing the intraocular pressure sensor to be inserted comprises rotating the intraocular pressure sensor in a direction that causes the screw to pass through the sclera.

8. The method of claim 1 wherein the intraocular pressure sensor further comprises a flare disposed underneath the top surface, and Wherein causing the intraocular pressure sensor to be inserted comprises moving the intraocular pressure sensor in a direction that causes the flare to pass through the sclera.

9. A method of implanting an intraocular pressure sensor, the method comprising;

determining an insertion location on a sclera of an eye of a patient;

loading an intraocular pressure sensor in an implantation wand, wherein the intraocular pressure sensor comprises a top surface and a coil disposed underneath the top surface;

placing the coil of the intraocular pressure sensor at the insertion location;

rotating the implantation wand to cause the intraocular pressure sensor to be inserted at the insertion location until the top surface of the intraocular pressure sensor is substantially flush with the exterior wall of the sclera; and

disengaging the implantation wand from the intraocular pressure sensor.

10. The method of claim 9 wherein the coil comprises a tapered tip configured to engage with tissue of the eye and substantially prevent the intraocular pressure sensor from being withdrawn from the eye after the intraocular pressure sensor has been inserted in the eye.

11. The method of claim 9 wherein the insertion location for as pseudophakic eye is approximately 3.5 millimeters from the limbus.

12. The method of claim 9 wherein the insertion location for a phakic eye is approximately 4 millimeters from the limbus.

13. The method of claim 9 wherein the intraocular pressure sensor comprises an outer bio-inert surface coating.

14. The method of claim 9 wherein at least a portion of an external surface of the intraocular pressure sensor comprises a porous cellular ingrowth coating.
