title: Drill-and-crack technique for nuclear disassembly of hard nucleus.
abstract: We describe a new technique for nuclear disassembly of a hard nucleus in cataract surgery. The drill-and-crack technique, which combines phaco chop and the prechopper, makes a deep hole (drill) in the central nucleus with the phaco tip and divides the nucleus (crack) with the prechopper inside the hole.
