Looking at the title picture should make you quite a bit uncomfortable because you still have most of the nucleus inside the eye but now there is a central puncture of the posterior capsule. When making the grooves and sculpting the nucleus, we have previously explained the proper path and we have even shown a case where this same complication occurred. The highlights of this video are recognizing the complication early, using viscoelastic to plug the hole, and then removing the rest of the cataract, and completing the case successfully. Congratulations to our winner Dr James Tian.
Inject a dispersive viscoelastic between the two halves of the lens nucleus to complete the separation.
