For a dense cataract, performing phaco chop is challenging because the central lens nucleus is so hard that the chop does not always propagate all the way through. Our guest surgeon, Dr Pradip Mohanta from West Bengal, India has a great technique to facilitate phaco chop in these brunescent cataracts: the submarine chop.
The idea behind this technique is to bury the phaco tip deep within the central endo-nucleus, thereby weakening it, and also to provide a strong purchase on the nucleus. This works very well, even in the most dense cataract cases. We thank Dr Mohanta for a great video and we are amazed at his expert hands.
