With horizontal phaco chop techniques, the nucleus is divided into two fragments using a chopper moving in the horizontal plane. During horizontal chopping, the nucleus is secured between the chopper and the phaco tip, which makes this technique less dependent than others on vacuum level. The capsulorrhexis must be 5 mm wide to allow surgical maneuvers to be performed without causing damage to the capsule. Hydrodissection is mandatory, and hydrodelineation is advisable. The sleeve of the phaco tip must adapt perfectly to the incision size to avoid fluid leakage through the main incision, an important issue when using high vacuum. The sleeve must be retracted backward to expose at least 1 mm of the metal tip so that it can penetrate the nucleus. It is important to ensure that the chopper is located beneath the anterior capsule; otherwise, the zonules or the anterior capsule will be torn during chopping. To impale the phaco tip, the surgeon should start stabbing the nucleus from the proximal edge of the capsulorrhexis, pointing toward the nucleus center without going beyond the proximal half of the nucleus. During this step, high vacuum and flow and burst ultrasound are used. Subsequent divisions are accomplished after the progressive rotation of the nucleus so that the face of the fragment to be impaled is parallel to the transverse surface of the phaco tip.
