This resident is learning horizontal phaco chop early in residency and this is case 50 from this young surgeon. The technique is pretty good for this stage of experience but there some some refinements that are needed. About half of the chops are successful in this case because occlusion is not maintained during the chop and therefore holding power of the nucleus is diminished. Also the chopper and phaco probe should initially be placed farther apart to maximize the propagation of the chop. If you are learning chop, watch carefully and you will certainly glean some valuable pearls.
