Abstract
In this study, we described and discussed the late onset spontaneous posterior capsule rupture with intraocular lens (IOL) dislocation years after uncomplicated cataract surgery and implantation of hydrophobic acrylic IOLs. Eight patients presented with spontaneous posterior capsule rupture and IOL dislocation 5–20 years after uncomplicated phacoemulsification and IOL (AcrySof, Alcon, US) implantation. None of the patients had undergone posterior capsulotomy in the past. Four of the patients admitted habitual eye rubbing. An intact and well-centered continuous curvilinear capsulotomy edge was observed in all cases. IOLs were dislocated or displaced behind the anterior capsulotomy with a significant decrease in vision. A large rupture with a curled edge of the broken posterior capsule was visible. Dislocated IOLs were removed, and a three-piece IOL was inserted in the sulcus in six cases and suture fixated to the sclera in two cases. Improved vision was achieved in all cases. Although the mechanism underlying this late complication is unclear, habitual eye rubbing or IOL design may play a role. Further investigation is needed to prevent this complication in the future.
