Posterior polar cataracts have a developmental defect at the center of the posterior capsule. This means that at the site of the opacity, the posterior capsule can be weak, very fragile, or even partially absent. This increases the risk of a posterior capsule rupture, particularly with hydro-dissection which should be avoided in these cases. We have featured many techniques for posterior polar cataracts including a couple of cases where the capsule ruptured and an anterior vitrectomy was required. You should review these videos prior to your scheduled case of a posterior polar cataract.
