Sculpt a nuclear groove • Setting : low asp rate, low vacuum, high phaco power (60%) => Peristaltic pumps 1. Divide and Conquer Technique • Sculpt two perpendicular trenches on the lens nucleus. • Then divided into 4 pieces, fragmenting and aspirating one by one Setting : high asp rate, high vacuum, low phaco power => Peristaltic pumps 2. Stop and chop Technique: • A deep trench is sculpted and split the nucleus into pieces with the two instruments to ensure a full separation • Chop again each piece one at a time and aspirate to remove • Setting : high asp rate, high vacuum, medium phaco power => Peristaltic pumps 3. Epinucleus • Draw loose pieces to phaco tip • Setting : low vacuum, high phaco power => Venturi pumps 4. I/A mode • Setting : High vacuum => Venturi pumps Remove residual cortex, polish and remove OVD Peristaltic More suited to sculpting and cracking where its holdability is beneficial in keeping the nucleus at the tip Venturi With its good followability Venturi pump is well suited to drawing small pieces to the tip and without the need of occlusion for vacuum works well for removal of segments, epinucleus, cortex and OVD THANK YOU FOR LISTENING ! ...
