The requirement for very deep akinesia has decreased with the use of modern phacoemulsification technique for cataract surgery. The use of topical anesthesia has increased as a way to reduce complications associated with anaesthesia with injection and to allow the most rapid visual recovery. The objective of this study was to assess the patient reported pain in phacoemulsification cataract surgery under topical anaesthesia versus peribulbar anaesthesia administered using an injection.
The subjects for this study were the patients undergoing phacoemulsification cataract surgery at HEH. Subjects were divided into two groups, one having topical anaesthesia for phacoemulsification and the other having peribulbar anaesthesia with injection. The data for the study was collected in a ten point visual analogue graphic pain scale. After the surgery was over the patients reported on the felt pain wherein the scale zero was assigned for no pain at all, 1 to 3 for mild pain, 4-6 for moderate pain and 7-10 for severe pain.
In total, 366 subjects received peribulbar anaesthesia and 336 subjects received topical anaesthetic drops. The mean pain score between the two groups was found to be higher in the peribulbar injection group (p <0.001). The mean pain score for both males and females was found to be higher in the peribulbar injection group (p<0.001 for both genders).
Topical anaesthesia for phacoemulsification cataract surgery tends to cause less pain and discomfort for patients.
随着现代超声乳化白内障手术技术的应用，对深度不动性的要求降低了。局部麻醉的使用增加了，以减少与注射麻醉相关的并发症，并允许最快的视力恢复。本研究的目的是评估在局部麻醉下进行超声乳化白内障手术与使用注射剂进行球周麻醉的患者报告的疼痛。
本研究的受试者是在 HEH 接受超声乳化白内障手术的患者。受试者分为两组，一组接受局部麻醉，另一组接受注射球周麻醉。研究数据采用十分制视觉模拟评分法收集。手术结束后，患者报告了感觉到的疼痛，其中零分表示完全无痛，1-3 分为轻度疼痛，4-6 分为中度疼痛，7-10 分为重度疼痛。
共有 366 例患者接受球周麻醉，336 例患者接受局部麻醉滴眼。两组之间的平均疼痛评分发现，球周注射组更高（p<0.001）。男性和女性的平均疼痛评分均发现，球周注射组更高（p<0.001）。
超声乳化白内障手术的局部麻醉会给患者带来较少的疼痛和不适。
