In the bag IOL dislocation following uncomplicated phacoemulsification☆

Abstract 

We present two cases of early post-operative, in the bag intraocular lens (IOL) dislocation following uncomplicated phacoemulsification. Dislocation occurred in the presence of capsular fibrosis and anterior capsular phimosis. One patient was a known diabetic, the other diagnosed with pseudoexfoliation syndrome. These are recognised risk factors for capsular fibrosis. Surgical management included enlargement of the anterior capsular opening using intraocular micro-scissors and vitreous cutter to facilitate the removal of the dislocated IOL from the capsular bag. Both patients achieved a satisfactory visual outcome following IOL exchange with a rigid, sulcus fixated posterior chamber IOL (PCIOL). We discuss the risk factors for capsular fibrosis and propose preventative strategies to reduce the incidence of in the bag IOL dislocation.
