Abstract
An eye-mountable composition, an eye-mountable device and a method for making the eye-mountable device are disclosed. In one aspect, an eye-mountable composition is disclosed, which may include a silicone hydrogel having silicon-containing monomer-derived units and hydrophilic monomer-derived units, a non-silicone hydrogel having non-silicon-containing hydrophobic monomer-derived units and hydrophilic monomer-derived units, or an elastomer. The composition is biocompatible, does not adhere to ocular tissue, and has a modulus of elasticity of 0.2 MPa to 10 MPa. Also provided is an eye mountable device including an electronics platform embedded in an eye-mountable composition, and a method for fabricating the eye-mountable device.
