posterior chamber deepens with capsule break

When the posterior chamber deepens during cataract surgery, it is usually a sign that the posterior capsule has been ruptured. This allows nuclear pieces to sink back into the anterior vitreous and we notice the extra deep posterior chamber. This is the time to stop (without withdrawing infusion from the eye) and add more viscoelastic via the paracentesis incision.

This case ends up with vitreous prolapse into the anterior segment which then needs to be cleaned up. There is are small retained nuclear fragments in the vitreous and we do not attempt to fish for these. Instead the anterior segment is cleaned up, a suclus IOL is secured, and the incision is sutured closed. The patient then underwent a pars plana vitrectomy with a retina specialist colleague. The outcome was good vision for the patient.
