SUMMARY

The latest technological advances are reviewed and a new instrument dedicated to ferrous foreign body removal, "the Rare-Earth IOM", is described. The Rare-Earth intraocular magnet is a simple but powerful instrument that replaces the older and bulkier electromagnets commonly used for the removal of intraocular ferrous foreign bodies. This instrument does not work at large distances from the eye and therefore cannot be used externally.

RESUMO

São descritos os avanços tecnológicos na remoção de corpos estranhos imantáveis e um novo imã intra-ocular ("Rare-Earth IOM"). Trata-se de um instrumento simples, porém potente que substitui os eletroímãs. Não funciona a grandes distâncias e, portanto, não pode ser usado externamente.
