title: Step-down technique.
abstract: From the beginning of nuclear fragment removal to the end, we progressively reduce all the parameters, ie, energy, vacuum, and aspiration flow rate, in a step-by-step manner proportionate to the posterior capsule exposure. This promotes adaptation of various parameters to the appropriate stages of surgery and allows the trainee and expert surgeon to perform posterior plane phacoemulsification. We recommend this technique for emulsification of dense as well as optimum-grade cataracts.
