Abstract
·AIM: To discuss the effect of the cystotome-assisted prechop technique performed in hard nuclear cataract phacoemulsification. <br> ·METHODS: One hundred and twenty-six patients ( 158 eyes) of age-related cataracts with nucleus density at grade Ⅲ-Ⅳ were randomly divided into two groups. Group A was performed a manual prechop technique using a surgeon-bent cystotome after the capsulorhexis, while group B was performed traditional phaco- chop without prechop technique. The average power ( AP ) , actual ultrasonic time ( U/S time ) , accumulated energy complex parameter ( AECP) of machine, average density of endothelial cells, endothelial cells loss, uncorrected visual acuity (UCVA), corneal edema and intraoperative complications were compared between groups. <br> ·RESULTS:The AP, U/S time and AECP of Group A were significantly lower than that of Group B (P<0. 05). At postoperative day 1, the corneal edema of Group A was slighter than the control with significant difference ( P<0. 05), so was the UCVA. While there was no significant difference of UCVA between groups at postoperative 1wk. The average corneal endothelium density of Group B was significantly lower than that of Group A at postoperative 1wk, and the average cell loss was higher than that of Group A. Two eyes of group A had posterior capsular rupture compared to 4 eyes of Group B. <br> ·CONCLUSION:Compared with traditional phaco-chop, the cystotome - assisted prechop technique presents shorter intraoperative ultrasound time and lower energy, while contributes to less corneal endothelial cell loss and better early postoperative UCVA.关键词
