    Background: To compare the efficacy of topicalanaesthesia with peribulbar anaesthesia inphacoemulsification.Method: This comparative analytical study wasconducted in the Department of Ophthalmology, FaujiFoundation Hospital, Rawalpindi, from February 2006 toJanuary 2007. A total of 200 patients who underwentphacoemulsification with intraocular lens (IOL)implantation were included in this study. Patients wererandomly assigned to peribulbar group (group 1, n=100)who received 4-5 ml of local anaesthetic (equal quantitiesof 2% xylocaine and 0.5% bupivacaine) in peribulbarregion and topical group (group 2, n=100) using 0.5%proparacaine in conjunctival sac every 5 minutes for halfan hour before surgery. Patients refusing informedconsent, having communication problem and nystagmuswere excluded from the study. All surgeries wereperformed by the same surgeon.Results: The difference between two groups regardinganalgesia was found to be statistically insignificant.Periocular group provided significant akinesia.Conclusion: Topical anaesthesia is an effectivealternative to peribulbar anaesthesia forphacoemulsification reducing the risks associated withperibulbar injection
