摘　　要：目的观察Infiniti超声乳化仪中智能超声（Intelligent phaco，IP）功能在成熟期白内障摘出术中的应用。方法将80例（128只眼）成熟期白内障患者随机分为A、B两组，其中A组40例（66只眼）行扭动超声乳化加IP功能白内障摘除术。B组40例（62只眼）行扭动超声乳化白内障摘除术，术中采用吲哚青绿行前囊染色后撕囊，术中观察前房稳定性，能量释放及时间，术后第1、3、7天观察角膜水肿、前房反应和视力情况。跟踪角膜内皮细胞变化。结果术中连续环形撕囊（Continuous circular capsulorhexis，CCC）成功率为96．8％，A组前房稳定性与B组相同（P〉0．05）；术中能量使用及超声时间明显少于B组，术后第1、3、7d时A组角膜水肿情况明显少于B组（P〈0．05）；术后第1、3天A组视力恢复明显好于B组（P〈0．05）。术中A组超声乳化针头受阻情况明显好于B组（P〈0．01）。结论Infiniti超声乳化IP功能在成熟期白内障摘除术应用是安全且高效、疗效好的手术方式，尤其对于成熟期中硬核白内障的处理，有效地利用了“冲击钻”的效应，对于硬核的乳化，优于单纯扭动超声乳化白内障摘出术。Objective To observe IP （Intelligent Phaco） function of the Infiniti phacoemulsifica- tion in the application of mature cataract extraction. Methods Eighty patients （128 eyes） with mature cataract were randomly divided into group A and B, in which group A of 40 patients （66 eyes） had IP features of twist phacoemulsification and cataract surgery, group B of 40 patients （62 eyes） had twist phacoemulsification cataract surgery. Anterior capsule was stained with indocyanine green line in- traoperatively for capsulorhexis. Anterior chamber stability, energy release and time were observed dur- hag operation. Corneal edema, anterior chamber reaction and vision conditions were examined on the 1 day, 3 and 7 days after surgery. Changes in corneal endothelial cells were tracked. Results The success rate in the CCC （continuous circular capsulorhexis） was 96.8%. Anterior chamber stability was the same both in Group A and B （P 〉0.05）. The intraoperative ultrasound energy uses and time in group A was significantly less than the group B; corneal edema on 1 day, 3 and 7 days after opera- tion of group A was less than group B （P 〈0.05）; moreover, visual acuity of group A was better than group B （P 〈0.05） 1 day, 3 and 7 days postoperatively. Obstacles in the needle of phacoemulsification surgery in group A was better than group B （P 〈0.05）. Conclusion The application of IP function of lnfiniti phacoemulsification in mature cataract surgery is safe, efficient and effective way of good operation, especially in the hard-core processing for mature cataract, effective use of the ＂impact drill＂ effect; for the hard core of the emulsion, better than Ozil phacoemulsification cataract extraction.
