Quiz: What is the huge danger seen in this photo?

  1. Excellent case and management. I like the way he used viscoelastic that prevented the nucleus falling back and also tried to protect the endothelium.
    However I think the capsule was violated during grooving because he went too far peripheral and at some point tip occlusion had happened and we can notice an incomplete punch sign indicating post. Capsule opening.
