Randomized Controlled Trial Comparative Study Clinical Trial
[Peribulbar anesthesia: comparing 1% ropivacaine and a mixture of 0.5% bupivacaine--2% lidocaine].
To compare the efficacy of 1% ropivacaine with a mixture of 0.5% bupivacaine and 2% lidocaine in peribulbar anesthesia for elective cataract surgery. ⋯ No difference between the groups was noted during the study regarding not only onset time, but also the duration of anesthesia and perioperative analgesia. A greater incidence of pain on injection was significantly reported in group 2 (p<0.001). Patients in group 1 had less need for top-up injection and showed better ocular akinesia (p<0.01).
