The application of microburst mode for phacoemulsification / 眼科

ABSTRACT

Objective To evaluate the effect on the corneal endothelial cell after phacoemulsification using the microburst mode with high vacuum. Design Prospective,observational case series. Participants 98 age-related cataract patients (120 eyes). Metheds All patients having phacoemulsification with the Alcon Legacy 20000 Everest software were assigned to 1 of 3 groups (the burst mode group,the pulse mode group and the continuous mode group). Main Outcome Measures Actual power,effect phaco time,visual acuity,corneal edema,and corneal endothelial cell loss. Results The mean actual power of the burst group was statistically lower than those of the other two groups,the effect phaco time of the burst group was statistically shorter than those of the other two groups. The corneal edema and the endothelial cell loss of the burst group were less than those of the other two groups. Conclusion The microburst mode with high vacuum increased efficiency of ultrasound power and decreased the loss of endothelial cell. (Ophthalmol CHN,2006,15 201-205)
