In this paper a new method of removal of foreign bodies from the superficial epithelium of the cornea is described. It is applicable to all foreign particles but is here chiefly concerned with the foreign bodies with an iron content encountered in industry. These quickly produce a rust stain, which becomes so firmly attached to the tissues that its removal often causes considerable damage to the corneal epithelium.
Injuries to the eye are the most disabling and costly of all nonfatal industrial accidents.1 Most of them are caused by foreign bodies in the cornea.2 Treatment should be prompt, efficient and economical, for infection delays healing, promotes scarring and may impair function, or even destroy the eye itself.3
The foreign bodies are usually hot4 and cause a burn when they strike the cornea. The burn and the subsequent rust stain become firmly attached to the surrounding tissue.
