【摘要】 目的进一步探讨表面麻醉下小切口非超声乳化白内障摘除人工晶状体植入术的安全性及有效忡。方法随机抽取220例(256眼)行小切口非超声乳化白内障摘除及人工晶状体植入术患者分为2组。表面麻醉组110例(126 眼),球后麻醉组110例(130眼),比较2组的手术效果及并发症。结果表向麻醉组手术时间明显短于球后麻醉组(P<0.01),而且并发症更少,术后1d及1周视力对比无显著性差异(P>0.05)。结论表面麻醉下小切口非超声乳化白内障摘除人工晶状体植入术是安全有效的,而且并发症少,简便易行。更多还原

【Abstract】 Aim To examine the safety and effectiveness of topical anesthesia for small-incision non-phacoemulsification cataract extraction and intraocular lens (IOL) implantation. Methods A random sample of 220 cases (256 eyes) of cataract were treated with small-incision non-phacoemulsification cataract extraction and IOL implantation. Before operation, they were divided into 2 groups: the group shaving topical anesthesia (126 eyes of 110 cases) and the group having retrobulbar anesthesia (130 eyes of 110 patients). The effectiveness of the operation and incidence of complications were compared between the 2 groups. Results Compared with the group haveing retrobulbar anesthesia, the time of operation was shorter and complications were fewer in the group having topical anesthesia (P <0.01). However there was no significant difference in postoperative vision (P≥0.5) between the 2 groups at the first day and the first week postoperatively (P>0.05). Conclusion Topical anesthesia can be used safely and effectively for small-incision non-phacoemulsification cataract extraction and IOL implantation with fewer complications. Besides it is easy to perform.更多还原
