目的：评价利多卡因作为表面麻醉剂在超声乳化白内障吸除术中的应用效果。
方法：我院2007-10/2011-09采用20g/L利多卡因注射液滴眼进行表面麻醉，行超声乳化白内障吸除联合人工晶状体植入术1 850例2 600眼，观察术中的镇痛效果。
结果：所有患者的手术过程顺利，93%的患者镇痛效果良好，术中无疼痛感，患者能很好地配合手术，未发生与麻醉相关的并发症，7%的患者术中诉术眼有胀痛感，均可忍受。术后1mo时，89.4%的术眼裸眼或矫正视力≥0.6。
结论：利多卡因作为表面麻醉剂行超声乳化白内障吸除联合人工晶状体植入术的镇痛效果良好，手术安全、舒适。

METHODS: There were 1 850 patients(2 600 eyes)who underwent phacoemulsification via surface anesthesia using 20g/L lidocaine. The analgesic effect was observed.
RESULTS: Totally 93% of 1 850 patients had not any pain during the surgery, a nice analgesic effect was showed, there was no complications duo to anaesthesia. Seven percent of all patients felt swelling pain during surgery but could tolerate. The naked or corrected visual acuity of 89.4% eyes was ≥0.6 one month after surgery.
