Management of the hard posterior polar cataract.

I describe a technique for managing the posterior polar cataract with a dense nucleus by initially sculpting a central trough to the depth of the polar opacity. The nucleus is partially cracked in the periphery, avoiding the polar opacity, and then chopped into quadrants without rotating. Next, the phaco tip engages the core of the nuclear quadrant while a cleavage plane is manually dissected along the lenticular lamellae using a Nagahara phaco chopper, with the tip rotated slightly so it points somewhat toward the equator of the lens, to a depth estimated to leave a nuclear shell, sparing the polar cataract. The nucleus is peeled away from the outer nucleus shell, which is kept in place by the phaco chopper. The intact nuclear plate is removed last and any capsular defect managed accordingly. This technique minimizes the risk for losing a nuclear fragment into the vitreous cavity.
