It is a pleasure to watch an expert surgeon doing cataract surgery and I really enjoyed learning from Dr. Alex Abdo Martins from Brazil. He shows us that we can chop the cataract without using the vacuum holding power of the phaco probe. He accomplishes this by trapping the nucleus between the phaco tip and the chopper, then mechanical forces can be applied to hold and split the cataract. This is all technique dependent and if the instruments are not directly apposed, this technique will not work as well. The video is also interesting because it is performed with the phaco probe in the left hand.
