How to administer burst phacoemulsification on the common phacoemulsification instrument.

Objective To investigate the method of burst phacoemulsification on the common phacoemulsification instrument.Methods Burst,traditional and pulse phacoemulsification with chop technique were used on 345 eyes of 315 patients with senile cataract. The degree of nuclear hardness was grade I - V . Results Postoperatively, the unconnected visual acuity was 0.8 or better in 76.81% ,80.29% and 87.25% at one day, one week and three months respectively. As compared with 152 eyes which were performed with the burst phacoemulsification, 122 eyes which were performed with the traditional phacoemulsification and 71 eyes which were performed with the pulse phacoemulsification, it suggested that the burst phacoemulsification time was the least, the incidence of the postoperative corneal edema was the lowest ( P = 0.000). Conclusion The burst phacoemulsification technique is preferable for phacoemulsification of cataract.
