The author, drawing upon over thirty five years experience of making and fitting plastic ocular prostheses, discusses the professional service which optometrists should be providing in their consulting rooms Lor those of their patients who have been fitted with an ocular prosthesis. He delineates the optometrist‐patient relationship. He describes the various types of eyes and how to recognise them, how to remove and insert a prosthesis. He outlines the examination of the socket, the surgical operation and the correct fit of the prosthesis, reviews the physiology of the monocular patient, comments upon the aesthetics of the cosmetic restoration and prefers some advice on the hygiene necessary for the patient's comfort.
