Clinical observation on linear burst model in phacoemulsification

Objective To observe the clinical efficacy of linear burst model in phacoemulsification.Methods 400 eyes of 400 cataract patients received phacoemulsification and intraocular lens implantation and were divided randomly into 4 groups based on 4 different ultrasonic energy models:continuous,pulse,burst and linear burst model.The actual ultrasonic time and cumulative ultrasonic energy were analyzed.The postoperative visual acuity,corneal endothelial density,corneal edema and complications were observed.Results The actual ultrasonic time and cumulative ultrasonic energy were significantly shorter in liner burst model group than in other 3 groups.The postoperative visual acuity was better,the corneal endothelial density was higher,the incidence of corneal edema and other complications were less in linear burst model group than in other 3 groups,and the differences were statistically significant.Conclusion The linear burst model in phacoemulsification has less damage to tissue and better clinical efficacy than other models.
