Filamentary keratitis, a little-known complication of cataract surgery, caused significant symptoms in the patients it affected. In most instances, the filaments disappeared in a week or two with therapy consisting of filament removal with (0.5%) silver nitrate impregnated cotton-tipped applicators. However, in two out of eight patients, the filaments recurred up to four years after surgery, although the visual acuity usually was not significantly affected.
