  • Title: [Effect of high-vaccum-manual-chop technique in phacoemulsification].
    Author: Li Z, He S, Wang F.
    Journal: Zhonghua Yan Ke Za Zhi; 2001 May; 37(3):185-7. PubMed ID: 11864418.
    Abstract:
    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.
