The patient is seated opposite to the doctor and ask to fix a look on his nose bridge. The device is installed at the level of eyes of the patient so that legs emphasis of a framework were located on the outer edges of eye-sockets, and hold hands (fig). By mirrors and a measuring scale define distance from edge of an outside wall of an eye-socket to top of a cornea. Normal this distance makes 17 — 19 mm.
