title: The use of perfluorophenanthrene in the removal of intravitreal lens fragments.
abstract: We used perfluorophenanthrene as an aid during pars plana vitrectomy in removing lens fragments dislocated posteriorly into the vitreous cavity. We reviewed the records of all patients (nine patients, nine eyes) referred with dislocated lenses who underwent pars plana vitrectomy with perfluorophenanthrene for removal of the lens material at Wills Eye Hospital from July 1, 1991, through Nov. 30, 1991. The lens was dislocated during cataract extraction in eight eyes. One eye had a history of nonpenetrating trauma and lens dislocation. In one eye a retinal tear was noted intraoperatively and treated. Six eyes had postoperative visual acuity of 20/50 or better. In all eyes the lens was removed without further complications. Perfluorocarbon liquids such as perfluorophenanthrene may enhance current techniques by allowing easier and safer removal of displaced lens fragments through the pars plana.
