Comparison between the prechopping method with a reverse chopper and the routine stop-and-chop method in treating cataract with grade IV hard nucleus.
Journal Français d'Ophtalmologie(2018)
摘要
The aim of this study was to compare the safety and efficacy between the prechopping method using a Reverse Chopper (iHPC) and the routine stop-and-chop (RSC) method in phacoemulsification of cataracts with grade IV hard nuclei (HNC (≥IV)). A total of 32 patients (32 eyes) scheduled for Phaco combined with intraocular lens (Phaco-IOL) for HNC (≥IV) from March 2015 to January 2016 were enrolled and randomly divided into two groups (the iHPC group, n=16 and the RSC group, n=16) so as to compare the effective intraoperative Phaco time, corneal edema 1–3 days after surgery, best corrected visual acuity (BCVA), and rate of loss of corneal endothelial cells (CECs) 1 month after surgery. The effective intraoperative Phaco time in the iHPC group was shorter (42.56s vs. 78.63s, P=0.000), the degree of corneal edema 1–3 days after surgery was less (P<0.01), the ratio of cases with BCVA>0.6 was higher, and the CEC loss rate was lower (13.36±2.85% vs. 25.77±3.81%, P=0.000). Compared with RSC, iHPC can reduce CEC injury in Phaco surgery, and the patients can recover their vision faster.
