Abstract

An eye-mountable device, having an anterior convex side and a posterior concave side, is packaged in a container having a base and a wall. The wall extends from the base and defines an opening of the container. Disposed within the container is a pedestal, which has a first end attached to the base of the container and a second end opposite the first end. The eye-mountable device is mounted on the pedestal such that the posterior concave side contacts the second end of the pedestal and the eye-mountable device is elevated from the base of the container. The opening of the container can be sealed by a lidstock.

Claims

1. A package comprising:

a container having a base and a wall, wherein the wall extends from the base and defines an opening opposite the base;

a pedestal disposed within the container, wherein the pedestal has a first end and a second end opposite the first end, wherein the first end is attached to the base of the container;

an eye-mountable device having a first side and a second side opposite the first side, wherein the eye-mountable device is mounted on the pedestal such that the second side contacts the second end of the pedestal and the eye-mountable device is elevated from the base of the container; and

a lidstock that seals the opening of the container, wherein the lidstock contacts the first side of the eye-mountable device to hold the eye-mountable device against the pedestal, and wherein the lidstock holds the eye-mountable device against the pedestal without distorting a shape of the eye-mountable device,

wherein the package is substantially free of liquids.

2. The package of claim 1, wherein the pedestal includes an annular ring, wherein the annular ring is segmented into a plurality of separate segments.

3. The package of claim 1, wherein the lidstock comprises a porous membrane configured to allow gas to permeate through the lidstock while preventing liquids from permeating through the lidstock.

4. The package of claim 3, wherein the porous membrane is configured to allow ethylene oxide to permeate through the lidstock.

5. The package of claim 1, wherein the container comprises a polymeric material.

6. The package of claim 5, wherein the polymeric material is polyethylene terephthalate glycol.

7. The package of claim 1, wherein the eye-mountable device comprises electronics that include at least one sensor.

8. The package of claim 7, wherein the at least sensor comprises an electrochemical sensor.

9. The package of claim 8, wherein the eye-mountable device further comprises an enzyme proximate the electrochemical sensor, and wherein the enzyme selectively reacts with an analyte.

10. The package of claim 9, wherein the enzyme is glucose oxidase and the analyte is glucose.

11. The package of claim 7, wherein the eye-mountable device is mounted on the pedestal such that the at least one sensor is presented in a specific orientation.

12. The package of claim 11, wherein the at least one sensor in the eye-mountable device faces the first side.

13. The package of claim 1, wherein the first side of the eye-mountable device is convex and the second side of the eye-mountable device is concave.

14. The package of claim 2, wherein the second end of the pedestal comprises inclined surfaces of the segments of the annular ring.

15. The package of claim 14, wherein the inclined surfaces conform to a curvature of the second side of the eye-mountable device.
