Day-case cataract surgery and the need for local anaesthesia are likely to increase. Retrobulbar (and peribulbar) anaesthetic injection is a common technique in cataract surgery, but serious complications are persistently reported. Subconjunctival injection is an alternative that avoids these risks. This retrospective study compares two groups of patients that underwent extracapsular cataract surgery under local anaesthetic. One group (retrobulbar) had uncomplicated retrobulbar injection with bupivicaine and hyaluronidase. The other group (non-retrobulbar) had superior bulbar, subconjunctival infiltration with bupivicaine and hyaluronidase. The operative complications and postoperative visual outcomes were similar in both groups. These results may encourage the investigation and adoption of the subconjunctival alternative to retrobulbar anaesthetic injection in cataract surgery.
日间白内障手术以及局部麻醉的需求可能会增加。球后（及球周）麻醉注射是白内障手术中的常用技术，但严重并发症仍时有报道。结膜下注射是一种可避免这些风险的替代方法。这项回顾性研究比较了两组在局部麻醉下接受白内障囊外摘除术的患者。一组（球后组）接受了布比卡因和透明质酸酶的无并发症球后注射。另一组（非球后组）接受了布比卡因和透明质酸酶的球上结膜下浸润。两组的手术并发症和术后视力结果相似。这些结果可能会促使人们对白内障手术中结膜下替代球后麻醉注射进行研究并采用。
