Background:Several different techniques for carrying out peribulbar anaesthesia have been described. The present study was conducted to compare Prilocaine 3% and a mixture of bupivacaine and lignocaine for peribulbar anaesthesia. Materials & Methods:80 patients requiring cataract surgery of both genderswere dividedinto 2 groups. Group I received a mixture of equal volumes of 2% lignocaine and 0.75 % bupivacaine, with adrenaline 5 µg/ml and hyaluronidase 75 µg/ml. Group II received 3% prilocaine, with felypressin 0.03 µg/ml and hyaluronidase 75 µg/ml.Globe and eyelid movements were measured at 2, 4, 6, and 8 minutes. Results: In group I, males were 21 and females were 19 and in group II, males were 22 and females were 18. In group I and group II, score 1was seen in 12and 7, score 2 in 7 and 5, score 3in 4 and 4, score 4 in 5 and 3, score 5in 3 and 2, score 6 in 2 and 3, score 7 in 2 and 2, score 8 in 3 and 2, score 9 in 1 and 6, score 10 in 1 and 4, score 11 in 0 and 2 and score 12 in 0 and 1 patients respectively. The difference was significant (P< 0.05). Conclusion: Prilocaine 3% was superior to a mixture of bupivacaine andlignocaine for peribulbar anaesthesia.
