PURPOSE: To compare the safety and efficacy of topical and retrobulbar anesthesia for combined phacotrabeculectomy. METHODS: In this prospective study, 40 consecutive patients having combined phacotrabeculectomy were randomized to receive topical (n = 20) or retrobulbar (n = 20) anesthesia. Operating conditions, patient comfort, and surgical outcome were evaluated. RESULTS: There was no significant between-group difference in operating conditions (p = 0.56), pain during (p = 0.41) or after (p = 0.23) surgery, or supplemental anesthesia required (p = 0.49). Few patients in either group were bothered by tissue manipulation or the microscope light, although more patients in the topical group were slightly bothered by touch sensation (p = 0.05). Chemosis, subconjunctival hemorrhage, and eyelid hematoma were seen almost exclusively in the retrobulbar group (p < 0.05). Inadvertent eye movement was present more frequently in the topical group (p = 0.04), although this did not pose a problem to the surgeon. CONCLUSION: Topical anesthesia is a safe and effective alternative to retrobulbar anesthesia for combined phacotrabeculectomy.
