DURING the past two years, at the New York Eye and Ear Infirmary, a relatively new instrument, the Berman Locator, has been found increasingly useful for intraocular foreign body work. In fact, experience with this device has demonstrated that the best foreign body work cannot be done without it.
Among a considerable number of cases of intraocular foreign bodies encountered during that period, we have had at least 6 in which the body was at first given up as nonmagnetic because of lack of response to the giant magnetic extractor but was later shown to be magnetic by the Berman Locator and was removed. The initial failures in these cases occurred because roentgenologic localization alone was inadequate to enable the surgeon to apply the proper magnetic power at the correct site to get a response.
In 1 case different surgeons made three attempts to remove the foreign body without getting
