Objective: To evaluate the advantage of perfluorocarbon liquid as a hydrokinetic manipulation tool during complex vitreoretinal surgery. Methods: Forty-two eyes with complicated retinal detachment were treated with vitrectomy and intravitreal perfluorocarbon liquid injection. Postoperative tamponade were obtained with silicon oil or gas. Results: Retinas were successfully reattached in all eyes intraoperatively, after a follow-up period of 3-6 months,34 of the 42 retinas (81%) remain attached . Conclusion: Perfluorocarbon liquid is an ideal hydrokinetic manipulation tool during complex vitreoretinal surgery.
