title: Sinus fracture--phacoemulsification technique for dense cataracts.
abstract: A method of performing phacofracture of hard nuclei is presented. Following a central horizontal fracture into 2 hemisections, the phacoprobe is plunged into the inferior hemisection to create a sinus within its dense wall. The chopper/second instrument is placed into the sinus and force is applied along the lateral walls of the sinus. The phacoemulsification probe breaks it and splits the inferior hemisection into two quadrants. A similar method is employed for the superior-nuclear hemisection.
