Objective: To investigate NeoSoniX swing handle phacoemulsification addition to the surgical technique and clinical efficacy. Methods: Continuous collected 402 cases of senile cataract patients (450), the application of Alcon Infiniti phacoemulsification cataract phacoemulsification instrument, all patients were randomly divided into two groups, A group: NeoSoniX swing handle phacoemulsification group of 211 cases (234) , B group: the standard continuous phacoemulsification group 191 cases (216), the two groups within the press core hardness (Emery grading) divided into two groups, core hardness I-Ⅲ level is a group of nuclear hardness IV ~ V level for the two groups, namely Al (177 眼), A2 (57 眼), Bl (162 eyes) and B2 (04 eyes). A, B group underwent phacoemulsification cataract surgery, A group blasting time is 30ms, swings 100% (± 2 degrees), negative pressure is 400mmHg, ultrasonic energy is 50%; B group negative pressure 400mmHg, maximum ultrasonic energy 50%. Record preoperative visual acuity, corneal endothelial cell number, cataract nuclear grade (Emery classification), mean intraoperative ultrasound energy, the effective ultrasound time, postoperative days 1 and 7 of the best corrected visual acuity, corneal edema and corneal endothelial cell number.

 

Results: Al and Bl, mean intraoperative ultrasound energy, respectively (14. 96 ± 10. 60)%, (16, 73 ± 9.80)%; effective ultrasound time was (27.92 Land 19.50) seconds, ( 30.47 Land 17.29) seconds, the difference was not statistically significant (P> 0.05). Postoperative day 1 of the best corrected visual acuity was ≥ 0.5, respectively, 141 (79.7%). 105 (64.8%), the difference was statistically significant (P <0. 05). 1 day after corneal endothelial count between the two groups was not statistically significant (P> 0.05). A2 and B2, the mean intraoperative ultrasound energy, respectively (19.96 ± 8.21)%, (27. 33 ± 11.32)%; effective ultrasound time was (41. 92 ± 19. 50) second, (59. 47 ± 17.29) seconds, the differences were statistically significant (P <0.05). Postoperative day 1 of the best corrected visual acuity was ≥ 0.5 were 28 (49.1%), 20 (37.0%), the difference was statistically significant (P <0. 05). 1 day after corneal endothelial cell count was statistically significant difference between the groups (P <0.05). Conclusion: IV-V-class nuclear phacoemulsification cataract surgery, the use of Micro-Blasting NeoSoniX swing handle combined mode, can significantly reduce the ultrasonic energy, reduce phaco time, the clinical results were satisfactory.
