Comparison of torsional and longitudinal modes using phacoemulsification parameters

According to M Rekas et al., in The Journal of Cataract & Refractive Surgery torsional phacoemulsification was found to be more effective than longitudinal phacoemulsification in the amount of applied fluid and the quantity of US energy expended. With the torsional method, it was possible to maintain a constant ratio of amount of fluid flow to quantity of US energy used, regardless of nucleus density. Read more.
