When the capsule breaks during cataract surgery and the vitreous prolapses into the anterior segment, it is important to clear this prior to insertion of the IOL. The traditional teaching is to make two limbal incisions and then perform a small-gauge bimanual anterior vitrectomy. But this requires that we keep pulling vitreous strands through the posterior capsule defect.
Another great option is presented here by Professor Ahmed Assaf from Egypt who is showing us the pars plana anterior vitrectomy technique. I have been teaching this technique to my residents for many years and it produces excellent results. By having the vitrectomy probe through pars plana, we are able to draw any prolapsed vitreous back into the vitreous cavity where it belongs. This approach also puts less traction and stress on the vitreous and that is a bonus for the safety of the retina.
