摘要:
An eye-mountable device is provided that includes electronics encapsulated within a rigid, gas-permeable polymeric material. The eye-mountable device includes an electroactive lens that can be operated to control an overall optical power of the eye-mountable device to restore an amount of visual accommodation of an eye to which the device is mounted. A method for fabricating the eye-mountable device is provided that includes applying an adhesive to secure lenses of the electroactive lens together and to maintain an amount of liquid crystal in the space between the lenses. The rigid, gas-permeable polymeric material can then be formed around the electroactive lens, electronics, or other elements of the eye-mountable device. The rigid, gas-permeable polymeric material can be mountable to a corneal surface of an eye or can be disposed on or within a soft polymeric material that is mountable to the corneal surface of the eye.
