Abstract: Purpose: To compare the efficacy and safety of topical anesthesia alone versus a combination of topical plus intracameral anesthesia in phacoemulsification cataract surgery. Methods: A total of 64 patients which were divided into two groups, 32 patients in each group. One group received topical anesthesia (Group A) and other received topical with intracameral anesthesia (Group B). The primary outcome measure was the level of intraoperative and postoperative pain. Secondary outcomes were to compare patient's vitals, level of satisfaction, phaco parameters, complications and surgeon's comfort between topical and topical with intracameral anesthesia during phacoemulsification. Results: In group A (1.50 ? 0.50) felt more pain as compared to the patients who underwent surgery under group B (0.65 ? 0.54) (p=0.006). The blood pressure at the time of surgery was significantly high in group A as compared to group B (systolic p=0.000, diastolic p= 0.001). It was observed that the difficulty level faced by the surgeon was significantly higher in group A as compared to group B (p=0.004). Conclusion: It was determined that patients who underwent phacoemulsification cataract surgery and got topical anaesthesia that was enhanced by intracameral lidocaine reported an appropriate level of satisfaction with the anaesthetic choice. In addition to that, the patients demonstrated stable hemodynamic parameters and had good control of their pain.
