Introduction:
Accurate positioning of transsclerally fixated intraocular lenses in vitrectomized eyes is difficult to achieve because of the lack of stability of the globe. External stabilization with a Flieringa device is widely used. Internal stabilization, however, with liquid perfluorocarbon seems to be more advantageous.
Methods:
Endostabilization with perfluorocarbon after pars plana vitrectomy prior to transscleral fixation of a posterior chamber lens was performed in 18 eyes. The intraocular lens floats on the surface of the perfluorocarbon. The level of the liquid can be adjusted to position the lens accurately. Transscleral fixation of the intraocular lens was followed by silicone oil injection in 4 eyes and by BSS injection in 14 eyes.
Results And Conclusions:
Endostabilization of the globe with liquid perfluorocarbon serves as a diaphragm preventing hemorrhage into the vitreous cavity and sliding of the intraocular lens, thus permitting proper positioning. There were no complications either intraoperatively, or postoperatively. Perfluorocarbon is a considerable aid in facilitating the positioning of a transsclerally fixated intraocular lens.
