A 6# needle was used.The site of first injection was the same as that for conventional retrobulbar anaesthesia, and the depth was 2 to 2.5 cm.Two mililiters was injected.Additional subcuaneous injection of 1 ml was given at the second site,which was located 0.5 cm from the lateral canthus.Intermittent pressure was applied for 10 minutes.Results Grade Ⅰ anaesthesia was achieved in 435 eyes(95%),grade Ⅱ and Ⅲ were achieved in 21 eyes (4.6%) and 2 eyes (0.4%),respectively.Conclusion Low dose peribulbar anaesthesia has a similar,if not better,effect in cataract surgery.
