Utilization of a curved aspiration-irrigation handpiece.
The safest way to completely remove the cortex from under the iris superiorly is with the angulated aspiration-irrigation handpiece. It is recommended that a .3 or .5 handle be utilized in low aspiration. As the instrument is rotated around its axis the opening of the aspiration handpiece is up, the cortex is grasped, and the surgeon is able to stay away from the posterior capsule. The incidence of vitreous loss is markedly reduced.
