WebTo stay below the maximum ultrasound output power, we set the highest MI to 1.1 in our ultrasound tests. Ultrasound power was gradually increased from the lowest setting (−30 dB, MI = 0.05) to the highest (0 dB, MI = 1.1) and then cycled back to the lowest again at an average rate of 1 dB/s. WebPurpose: To compare surgical efficiency and multiple early clinical outcome variables in eyes undergoing phacoemulsification using either transversal or torsional ultrasound systems. Setting: Assil Eye Institute, Beverly Hills, CA, USA. Design: Prospective, randomized, clinician-masked, contralaterally controlled single-center evaluation.
