方法：于2010-09/12采用40g/L爱尔卡因表面麻醉，对92例96眼老年性白内障眼，行小切口手法白内障摘除联合人工晶状体植入术，观察其麻醉效果、术中、术后并发症和疗效。

结果：在表面麻醉下，92例94眼能顺利完成小切口手法白内障囊外摘除联合人工晶状体植入手术。疼痛指数和术中眼球运动和眼睑痉挛的情况均在可耐受范围。95%患者表示满意。结膜下注射(50眼，52%)和固定上直肌(31眼，32%)是疼痛比较明显的两个环节，其次是烧灼巩膜血管(16眼，17%)，转核及娩核(13眼，14%)，巩膜隧道切口(12眼，12%)，注吸黏弹剂(9眼，9%)，植入人工晶状体(1眼，1%)。它们的疼痛差异有统计学意义(P<0.05)。

结论：在农村地区进行白内障防盲时，采用有效的止痛措施后，小切口非超声乳化白内障囊外摘除联合人工晶状体植入手术中采用表面麻醉的方法，安全可行，可有效的提高白内障防盲的工作效率。

METHODS:Small incision cataract surgery and intraocular lens implantation under surface anaesthesia with 40g/L Alcaine eye drops were performed on 92 patients(96 eyes)from September, 2010 to December, 2010. The pain during the operation, complications and curative effect were observed and recorded.

RESULTS: Surgery was successfully performed on 92 patients(94 eyes)under surface anaesthesia. 95% patients considered the intraoperative aches-and-pains index, eye movements and blepharospasm as tolerable and they were satisfied with the operation. Subconjunctival injection(50 eyes, 52%)was the most painful operating procedure, followed by fixed suture of superior rectus(31 eyes, 32%), cautery of sclera vascular(16 eyes, 17%), nuclear extraction(13 eyes, 14%), sclera tunnel incision(12 eyes, 12%), irrigating-aspirating viscoelastic agent(9 eyes, 9%)and lens implantation(1 eye, 1%). There was significant difference in the pain caused by these operating procedures(P<0.05).

CONCLUSION: In the prevention of blindness caused by cataract in the rural area, small incision cataract surgery combined with intraocular lens implantation under surface anaesthesia is safe and feasible when utility measure is taken for pain. It can improve the efficiency of the cataract surgery for prevention of blindness.
