Claims23
A composition for reapplying a detached retina to the chorioid of an eye, containing a therapeutically effective amount of at least one liquid perfluorocarbon (PFC) characterized by a PFC-mixture wherein said PFCs are purified to be free from free from C.dbd.C double bonds and C--H bonds.
A composition for unfolding a detached retina for reapplying to the chorioid of an eye containing a therapeutically effective amount of at least one liquid perfluorocarbon (PFC) wherein said perfluorocarbon is purified to be free from C.dbd.C double bonds and C--H bonds by refluxing with a secondary amine and a strong base and separating the products formed by reaction with the secondary amine from the unchanged perfluorocarbon and by reacting produced compounds having H--F bonds with iodide ions.
