Arch Ophthalmol. 1965;74(5):674-678. doi:10.1001/archopht.1965.00970040676016
Abstract

Metallic foreign bodies imbedded in the cornea are a frequent problem in ophthalmic practice. This problem is aggravated when the particle is ferrous and a rust ring results. It is reasonably well accepted that complete removal of the rust stain accelerates healing while decreasing secondary irritation and corneal opacification.1-3 Among the variety of mechanical means advocated for the removal of rust rings are burrs, spuds, and needles.4-7 At best, however, manipulation usually extends beyond the portion of cornea involved and adds to the area of opacification. Furthermore, extensive manipulation significantly increases the chances of secondary infection. These factors assume even greater importance when it is realized that most such foreign bodies are limited to the optical zone which comprises only 25% of the corneal area.8

It would be a distinct therapeutic advance, therefore, if corneal rust rings could be eliminated by medical means. This report presents data
