Claim Text:
1. An eye-mountable device comprising: a transparent polymeric material having a concave surface and a convex surface, wherein the concave surface is configured to be removably mounted over a corneal surface of an eye and the convex surface is configured to be compatible with eyelid motion when the concave surface is so mounted; an antenna at least partially embedded in the transparent polymeric material; an expandable member at least partially embedded in the transparent polymeric material and configured to expand and apply a force to the corneal surface; a sensor at least partially embedded in the transparent polymeric material configured to detect a resistance to deformation of the cornea in response to the force applied by the expandable member; and control electronics at least partially embedded in the transparent polymeric material, wherein the control electronics are configured to: (i) use the sensor to measure the resistance to deformation of the cornea; and (ii) use the antenna to communicate data indicative of the measured resistance to deformation of the cornea to an external reader, wherein the resistance to deformation of the cornea in response to the force applied by the expandable member is indicative of intraocular pressure of the eye.
