Use of Perfluoroperhydrophenanthrene in the Management of Posteriorly Dislocated Crystalline and Intraocular Lenses

We describe a series of 28 patients in whom a posteriorly dislocated crystalline or intraocular lens was successfully removed with the intraoperative use of perfluoroperhydrophenanthrene (Vitreon), a heavy liquid perfluorocarbon. The Vitreon was used to float the lens into the midvitreous cavity, thereby avoiding hazardous micromanipulation with intraocular instruments in the macular area. In addition, the Vitreon served to protect the posterior retina by keeping the posteriorly dislocated lens fragments from falling backward onto the posterior pole as the lens was being removed from the eye. Postoperative visual acuity improved in 73% of the patients, remained the same in 15%, and worsened in 12%.
