目的:分析115例双眼表面麻醉在超声乳化手术中的应用情况。方法:术中采用4g/LAlcaine滴眼液双眼表面麻醉,经巩膜隧道切口完成常规超声乳化手术,植入单片式PMMA硬质人工晶状体或一片式折叠式人工晶状体。结果:85%手术患者术中没有任何疼痛感,15%患者在手术不同步骤时有疼痛感;术后因角膜上皮脱落导致术眼疼痛的12例,术后35例术眼有异物感、干涩等不适;对侧眼出现不适感15例,其中2例轻微视力下降,均在1wk内恢复。结论:双眼表面麻醉方式行超声乳化手术镇痛效果良好,手术安全、舒适。

·AIM:To report the application of surface anesthesia in binoculus for phacoemulsification in 115 cases.·METHODS:The surface anesthesia regimen consisted of 4g/L Alcaine.Phacoemulsification was performed through a scleral tunnel incision.The one-piece PMMA or three-piece silicon intraocular lens was implanted.·RESULTS:Totally 85 percent of 115 cases had not any pain during the surgery,15 percent felt pain during different operative stages.12 cases felt pain caused by epithelium’s loss,35 cases felt foreign body sensation,dry and discomfort;that contralateral eye discomfort occurred in 15 cases,including two cases of mild visual loss.All cases recovered in a week.·CONCLUSION:The phacoemulsification under surface anesthesia of binoculus is safe and effective.·
