Foreign substances may be removed from a mammalian body cavity containing an aqueous phase by injecting into the cav- ity a water-immiscible, optically clear, biocompatible debridement fluid to at least partially displace the aqueous phase; and rem- oving the aqueous phase and the foreign substances. In addition, a method is provided for visualizing a transparent foreign sub- stance in a mammalian body cavity using a water-immiscible; optically clear, biocompatible fluid having a refractive index different from that of water. The debridement fluid may also be used to reposition desirable substances, such as a lens in an ocu- lac cavity, or to remove a secondary membrane from a cavity lining or structure. Preferably, a liquid heavier than water, such as a perfluorocarbon liquid, is used as the debridement fluid.
