Abstract
Example eye-mountable devices and methods for fabricating eye-mountable devices are described. A method may include applying a first amount of polymerizable material to a ring-shaped structure, where the ring-shaped structure comprises at least one sensor configured to detect an analyte. The method also may include positioning the ring-shaped structure with the first amount of polymerizable material applied thereto in a mold, where the mold is configured to form an eye-mountable device. Further, the method may include applying pressure on the ring-shaped structure in the mold while curing the first amount of polymerizable material. Still further, the method may include adding a second amount of polymerizable material to the mold with the ring-shaped structure therein, and curing the second amount of polymerizable material to form an over-molded polymer layer such that the ring-shaped structure is at least partially enclosed in the eye-mountable device.
