Cortical pre-aspiration prior to phacoemulsification is a useful strategy for reducing lens mobility and improving surgical control before nucleus removal. By gently aspirating loose or partially separated cortical material early in the case, typically after capsulorhexis creation and hydrodissection, the surgeon creates space around the nuclear rim and decreases zonular stress during subsequent manipulation. Pre-aspiration also helps prevent cortex from becoming trapped behind the nucleus, which can streamline cortical clean-up later and reduce overall ultrasound time. When performed with low vacuum and controlled aspiration parameters, it is a safe adjunct that can make the nucleus more responsive to rotation and longitudinal movement, contributing to smoother, more predictable phaco.

I’ve been doing this for about 6 months now. I find that it reduces friction with the nucleus and capsule, making subsequent maneuvers within the bag easier and with less strain/torque on the zonules
