[Effect of high-vaccum-manual-chop technique in phacoemulsification]
Objective:
To study the effect of high-vaccum-manual-chop technique to reduce complications related to phacoemulsification.
Methods:
The correlation between the relative energy complex parameter (RECP) and the postoperative corneal edema rate (CER) in manual-chop and phaco-divide groups was statistically studied.
Results:
The intraoperative mean relative ultrasound power and the mean time of ultrasound phacoemulsification were increased with the increase of the lens nucleus hardness. A significant difference existed between the mean time of the ultrasound phacoemulsification of the two groups (t = 3.1467, P < 0.01). The comparison between the mean relative ultrasound power of the two groups has no significant difference (t = 0.1874, P > 0.05). Positive correlation was observed between RECP and CER (r = 0.97, P < 0.01).
Conclusion:
High-vaccum-manual-chop technique may reduce the postoperative complications related to phacoemulsification, and RECP can be taken as a reliable index to evaluate the safety of phacoemulsification.
