Four years after her capture by Vanchat, Akela Amador was given the Backscatter X-Ray Eye implant by HYDRA's Centipede Project upon being sold to them by Vanchat. A former MI6 agent known as the Englishman was also given an eye implant. It forced Amador and the Englishman to do the Centipede Project's missions or they would trigger their eye implants' kill switch. Amador however, was spared from that fate when Leo Fitz and Jemma Simmons removed Amador's implant. The Englishman, however, was killed when Phil Coulson confronted him. 
Following Amador's capture and freedom from the implant, Centipede installed the implants in the Centipede Soldiers. After an ambush at the Centipede Project's Oakland Base, Coulson's Team learned from Brian Hayward's corpse that he was given the same implant as Amador.
Following his apparent "death", agent trainee Mike Peterson, was given this implant. It forced him to work for the Clairvoyant, who revealed himself as John Garrett and was working with HYDRA. However, Peterson was then freed when Skye freed him and his son from Garrett's control when Phil Coulson's team invaded Cybertek.
The Centipede Soldiers captured by the United States Armed Forces during the Battle at Cybertek had their Eye Implants removed in hopes of giving them normal lives. Peterson continued to use the implant when he returned to work for S.H.I.E.L.D. until it was removed by List.
S.H.I.E.L.D. created a variation of the Backscatter X-Ray Eye Implant. With a pair of these, Fitz and Simmons hoped it would attract the attention of Holden Radcliffe and manage to meet him with the help of his assistant Anon. He recognized the Backscatter X-Ray Eye Implant as having been previously developed by Cybertek.
The Backscatter X-Ray Eye Implant, developed by HYDRA, is a prosthetic ocular implant that allows the user to see through solid objects when their eyes are closed. It also allows for a form of night-vision.
The unit has an internal power source and the user is capable of adjusting or repairing the unit by themselves with a specialized tool-kit.
The user is under the constant watch of their handler who sends orders and instructions to the user through the eye implant. The handler watches the eye's user for any signs of betrayal or capture.
If the implant's user shows signs of disobeying orders, then the handler ensures the operative's loyalty by activating a fail-safe, incapacitating the user with a pain described to be like an "electric migraine." If the user is captured or goes rogue, then the handler activates a kill-switch, killing the operative instantly.
Some of the handlers were, in turn, also installed with the implant and watched to ensure their own loyalty.
