Following hydrodissection, the endonucleus is removed piecemeal while the lens is rotated using a phaco tip. A peripheral groove is created in the 6 o’clock direction and, after lens rotation through 180° using the phaco tip, another 6 o’clock groove is created. After a further 90° of lens rotation, the residual plate is readily flipped over and emulsified. The entire procedure requires only a phaco tip; it is not necessary to create a corneal side port or use any instrument.
