Intralenticular foreign bodies are neither unequivocal antecedents of cataract nor indications for immediate lens extraction. Minute foreign bodies either chemically active or nonmagnetic are preferably left in the lens. Small to medium size magnetic foreign bodies should be extracted with minimal magnetic gauss carefully along the entrance pathway. Capsular tears under 2 mm tend to seal, whereas those of 3 mm or larger may lead to opacity. Major foreign bodies causing extensive cataract should be removed by cryoextraction of the lens, unless multiple capsular tears or perforations are present. Under these conditions, the lens may be allowed to absorb unless glaucoma or uveitis require removal. Foreign bodies should be placed in culture broth after extraction rather than taped to the chart.
