Aim: The purpose of this study was to compare the effects of peribulbar and topical anesthesia in cataract surgery on patient and surgeon comfort, anesthetic agent requirement, adverse medical events and the relationship of anesthetic method with these parameters. Material and Method: After the approval of Institutional Review Board 40 patients (ASA I-III, 45-85 years) undergoing cataract surgery with facoemulsification method were randomly divided into two groups. Twenty of them underwent cataract surgery under peribulbar anesthesia (group LA), and 20 under topical anesthesia (group TA). After 5 minutes from patient sedation venous blood was taken for blood-gas values. Pain of the patients was evaluated by Visual Analogous Scale (VAS) at the onset, 10 minute intervals intraopcratively, at the end, 1 and 24 hours after operation. Assessment of level of sedation was made by using part of The Observer's Assessment of Alertness and Sedation (OAA/S) scale. Awaking time and need for additional anesthetic drug were recorded. At the end of the surgery; cooperation of the patients was evaluated by the anesthesiologist. Results: There were no differences in VAS scores intraopcratively and postoperatively including 1. and 24. hour scores, and also no difference was found about anesthetic requirement between two groups (p>0.05). OAA/S scores of the patients in group TA were higher from group LA at 5.-10.-15.-20.-25.-30.-35. minutes (p<0.05). There were no differences in awaking time between groups. Although mean blood pressures of the patients in group TA was higher than group LA at 15.-20.-25. minutes (p<0.05) all measurements were in normal range. Cooperation scores of the patients in group TA were also higher than group LA (p=0.01). Conclusion: Patient comfort and surgical conditions were found similar in both anesthetic techniques that were used. Problem about patient cooperation was observed in topical anesthesia however it was solved by preoperative counseling and sedation.
