However, the attached video contradicts these assertions, as the following were observed: (i) a second instrument is used to split the grooved nucleus, to chop the quarters, and to manipulate the fragments; (ii) in all, the authors used more than three instruments: cannula for saline or for ophthalmic viscoelastic device, phaco tip, chopper, and irrigation/aspiration cannula; and (iii) the wound leakage around the chopper is obvious.
