A new technique for repositioning a posteriorly dislocated intraocular lens.

Pars plana vitrectomy was performed to treat a complete posterior dislocation of an intraocular lens in seven patients. The method that the authors have developed appears to be safer and simpler than those previously described. The haptics are externalized for a secure tie at the proper site, and are then reinternalized back through the pars plana sclerotomies. Only two small needle perforations are made for the scleral fixation of the intraocular lens in the ciliary sulcus. Perfluorocarbon liquid is used to prevent intraoperative retinal damage.
