[Treatment of an orbital defect with an eye prosthesis with an electronically controlled eyelid, synchronous to the intact eye]

For the treatment of an orbital defect after exenteratio orbitae, an eye prosthesis with flexible upper eyelid was developed. The artificial eyelid moves synchronously with the natural contralateral upper eyelid by electronic control. The electric signal of a light barrier mounted on to a spectable frame in front of the intact eye is intensified and transmitted to an electromagnet. The electromagnet is located in the obturator prosthesis and lifts the artificial eyelid.
