Is implantation of a second intraocular lens following dislocation of a prior implant into the vitreous cavity an avoidable unperfected medical procedure?

Background: The implantation of an intraocular lens into the capsular bag i s a common precedure 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 r emarkable, as a second intraocular lens has been implanted while a dislocat ed intraocular lens was still in the vitreous cavity. Patient: We report on a 70-year-old patient who underwent cataract surgery. After a break in the posterior capsule the intraocular lens dislocated int o the vitreous cavity. A second intraocular lens has been implanted in the ciliary sulcus. 41 days after cataract surgery the dislocated intraocular l ens has been removed by pars-planavitrectomy without any problems. Conclusion: Intraocular lens implantation in the ciliary sulcus is not prov ed to be a hindrance with regard to the transcleral removal of a posteriorl y dislocated intraocular lens, following the principles of intraocular fore ign body surgery.
