For a resident surgeon with about 350 cataract cases, adopting vertical chop is a natural progression toward greater efficiency and control. The key principle is bringing the phaco tip fully into the nucleus to obtain a firm purchase before initiating the chop. Using high vacuum and stable chamber settings, impale the nucleus deeply so the tip holds it without slipping. With the nucleus firmly engaged, introduce the chopper vertically at the equator through the capsulorhexis edge. Keep the chopper close to the phaco tip to avoid zonular stress. Drive the chopper straight downward while simultaneously lifting slightly with the phaco tip to propagate a full-thickness vertical crack. Complete the separation by spreading the instruments horizontally. Each subsequent chop is performed on the remaining hemi-nucleus without rotating the lens excessively. Vertical chop rewards precision and teaches excellent instrument control, making it an ideal next step for an advancing resident surgeon. What is your critique or advice for this young surgeon?
