Pars plana vitrectomy for posteriorly dislocated intraocular lenses: risk factors and surgical approach

ConclusionPosterior intraocular lens dislocation is becoming more prevalent. The main underlying causes found in this series were previous vitrectomy, myopia and recurrent intra-vitreal substance injections. Visual acuity improved in most cases after lens repositioning; however visual outcome is often limited due to associated ocular co-morbidities despite adequate lens position. Despite complete lack of zonular support, a posteriorly dislocated IOL can often be preserved by repositioning and fixation of the lens in the posterior chamber. Pathologies primarily associated with this type of lens malposition include history of vitrectomy, high myopia and multiple intravitreal substance injections.
