title: [Is the implantation of a second intraocular lens prior to the removal of the first implants remaining in the vitreous cavity incorrect medical treatment?].
abstract: BACKGROUND
  The implantation of an intraocular lens into the capsular bag is a common procedure in modern cataract surgery. In case of a break of the posterior capsule it is possible to implant the intraocular lens by rhexis-, ciliary sulcus- or pars-plana-fixation. The following case is in so far remarkable, as a second intraocular lens has been implanted while a dislocated intraocular lens was still in the vitreous cavity.
  
  
  METHODS
  We report on a 70-year-old patient who underwent cataract surgery. After a break in the posterior capsule the intraocular lens dislocated into the vitreous cavity. A second intraocular lens has been implanted in the ciliary sulcus. 41 days after cataract surgery the dislocated intraocular lens has been removed by pars-plana-vitrectomy without any problems.
  
  
  CONCLUSIONS
  Intraocular lens implantation in the ciliary sulcus is not proved to be a hindrance with regard to the transcleral removal of a posteriorly dislocated intraocular lens, following the principles of intraocular foreign body surgery.
