Intraoperative performance and postoperative outcome comparison of longitudinal, torsional, and transversal phacoemulsification machines

Abstract

All 3 phacoemulsification machines were effective with no significant intraoperative complications. The torsional machine outperformed the transversal and longitudinal machines, with a lower mean needle time, less chatter, and improved followability. This corresponded to less corneal edema 1 day postoperatively and better visual acuity.
