Removal of silicone oil from a silicone intraocular lens

Although F6H8, a semifluorinated fluorocarbon, is a solvent for silicone oil, the solvent is not powerful enough to dissolve the oil and clean the lens simply by contact. It requires the force of a fluid jet to detach the oil form the surface of the silicone lens. This is the first time, that silicone oil can be removed from silicone intraocular lenses, avoiding the lens exchange. However a complete removal of remnants of silicone oil from the  eye is not possible, because droplets may be hidden entangled in the vitreous base, released at some time point later and again attach to the silicone lens.
