Packaging for an active contact lens
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.
1. A method comprising:
providing a container having a base and a wall, wherein the wall extends from the base
and defines an opening opposite the base, wherein the container includes a pedestal that has a first end and a second end opposite the first end, wherein the first end is attached to the base of the container;
mounting an eye-mountable device on the pedestal, wherein the eye-mountable device has an anterior convex side and a posterior concave side opposite the anterior convex, and wherein mounting the eye-mountable device on the pedestal comprises mounting the eyemountable device 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; and
sealing the opening of the container with a lidstock such that the lidstock holds the eyemountable device against the pedestal without distorting a shape of the eye-mountable device
and the container is substantially free of liquids.
2. The method of claim 1 , further comprising:
forming the container from a polymeric material.
3. The method of claim 1 , wherein the pedestal includes an annular ring segmented into a plurality of segments, and wherein each segment is separated by a predetermined distance from a neighboring segment.
4. The method of claim 1 , wherein the lidstock is configured to contact the anterior convex side of the eye-mountable device to hold the eye-mountable device against the pedestal.
5. The method of claim 1 , wherein the eye-mountable device includes a sensor configured to measure concentration of an analyte, wherein the sensor includes a reagent that selectively reacts with the analyte.
6. The method of claim 1 , wherein the eye-mountable device includes a biological enzyme.
7. The method of claim 1 , wherein the lidstock comprises a porous membrane configured to allow gas having molecules of a predetermined size to permeate through the lidstock while preventing liquids from permeating through the lidstock.
8. The method of claim 7 , further comprising:
causing a sterilizing gas having molecules smaller than the predetermined size to permeate through the lidstock so as to sterilize an interior of the container including the eye-mountable device.
9. The method of claim 8 , wherein the sterilizing gas comprises ethylene oxide.
10. The method of claim 1 , wherein the container comprises a polymeric material.
11. The method of claim 10 , wherein the polymeric material is polyethylene terephthalate glycol.
