Very hard cataracts continue to be a challenge to phacoemulsification due to the difficulty in breaking the nucleus and also in separating the broken nucleus from the adjacent epinucleus. The present technique is the presentation of a surgical maneuver which uses the Nagahara chopper and the phaco tip to divide the nucleus (including the epinucleus) as a whole and then emulsify it using little time and not very much phaco power. Cataratas muito duras continuam sendo um desafio para a facoemulsificação devido à dificuldade em quebrar o núcleo e também em separar este pedaço quebrado do epinúcleo adjacente. Esta técnica é a apresentação de uma manobra cirúrgica ("Faco rasteira"), em que se utiliza o Nagahara "chopper" e a caneta de faco para dividir o núcleo (incluindo o epinúcleo) em sua totalidade e assim emulsificá-lo, utilizando tempo e poder de ultra-som baixo
