Cortical removal simplified by J-cannula irrigation.

Subincisional cortical removal is one of the more specific obstacles impeding the performance of uneventful cataract extraction. In this technique, staged use of a J-cannula irrigates the cortex remaining after phacoemulsification, particularly in the subincisional space. This is followed by standard automated aspiration. The irrigation procedure is independent of a small pupil or capsulorhexis and typically allows for complete cortical cleanup in less than 1 minute. The details of the procedure, used in more than 3000 cases, are reported.
