Peribulbar anaesthesia (PBA) is commonly used technique for Manual small incision cataract surgery (MICS) however, feared with complications. Sub-Tenon anaesthesia (STA) is relatively new technique with better safety profile however, requires supplementary injections due to lesser akinesia. We compared both the technique to assess level of akinesia, requirement of supplementary injections, pain during surgery, complications and patient’s satisfaction. Two groups of 50 patients each were given either PBA or STA at random. Supplementary injections were given after 10 minutes if adequate akinesia did not occur. Data was collected and analysed for akinesia, number of supplementary injections in each group, pain during surgery, chemosis and sub-conjunctival hemorrhage and patient’s satisfaction. Complete akinesia occurred in 86% in PBA group compared to 68% that in the STA group p=0.033(OR=2.8, CI95% (1.42-5.84). Number of supplementary injections were 24% in STA group and 6% in PBA group (p= 0.001) (OR=0.238, 95%CI (0.09-0.58). Seventy eight percent of PBA group and 62% of STA group experienced no pain during the operation (p=0.014) (OR=2.17, 95% CI (1.16-4.04).
