Abstract. Purpose:To report the outcome of longitudinal and torsional phacoemulsification with straight and angled tips. Cases and Method:Cataract surgery was performed on 84 eyes with density grade from 2 to 3.5 after Emery-Little system. Straight tip was used to divide and fracture the nucleus in 33 eyes. Straight and Kelman tips were used in 51 eyes to measure the total energy and duration of ultrasound application using torsional and longitudinal vibration. Results:The lens nucleus could be divided and aspirated by straight tip in eyes with density grade of 3 or less. Straight tip was less efficient than Kelman tip but was more efficient than conventional longitudinal vibration when added by ultrasound nuclear division. Conclusion:Torsional phacoemulsification-aspiration is possible and efficient using straight torsional tips.
