This study evaluated the efficacy and side‐effects of plain ropivacaine compared with ropivacaine–lidocaine and bupivacaine–lidocaine mixtures for peribulbar blocks in cataract surgery. Ninety patients were randomly allocated to three groups and received peribulbar blockade using one of the three solutions. Speed of onset and quality of blockade were assessed using akinesia, surgical satisfaction and patient satisfaction. Complications and cardiovascular side‐effects were noted. There was a slower onset of akinesia using ropivacaine alone, although at 10 min after injection all groups were equal in this respect. There was no difference in surgical or patient satisfaction between the groups. There were no differences in pain on injection, preblock and postblock blood pressure, heart rate or oxygen saturation. The optimal time to surgical incision after peribulbar blockade is not less than 15 min and plain ropivacaine fulfils this criterion.
