目的:评价表面麻醉在白内障超声乳化摘除术中的临床效果。方法:把82例(91眼)行白内障超声乳化摘除术患者分成两组,40例(45眼)采用表面麻醉,42例(46眼)采用常规局部麻醉,比较两者的效果。结果:表面麻醉组手术前准备时间比常规局麻组短(P<0.05),术后视力恢复比常规局麻组快(P<0.01);而两组手术时间和止痛效果无显著性差异(P>0.05)。结论:表面麻醉具有安全,有效和操作简便的特点,适宜于在白内障超声乳化摘除术中推广作用。眼科学报1998;14:242～244。 Objective: To evaluate the clinical effect of surface anesthesia in phacoemulsification cataract extraction. Methods: Eighty-one patients (91 eyes) undergoing phacoemulsification were divided into two groups. Forty-five eyes (45 eyes) received topical anesthesia and 42 cases (46 eyes) received conventional local anesthesia. Results: The preparation time of the surface anesthesia group was shorter than that of the conventional anesthesia group (P <0.05), and the visual acuity recovery rate of the anesthesia group was faster than that of the conventional anesthesia group (P <0.01). There was no significant difference between the two groups in the operation time and analgesic effect P> 0.05). Conclusion: Surface anesthesia is safe, effective and easy to operate. It is suitable for the promotion of cataract phacoemulsification. Journal of Ophthalmology 1998; 14: 242-244.
