Study on peribulbar versus topical anaesthesia in subjects undergoing phacoemulsification

Abstract

Introduction: Phacoemulsification was first introduced by Charles Kelman in 1967. IOL implantation is done according to the power of lens calculated using various intra ocular lens (IOL) calculation formulae. By customizing the IOL during cataract surgery, we can provide patients with best refractive outcomes, even in high myopes and hypermetropes. Aim and Objective of the study: The objective of the study to compare the efficacy of topical Anaesthesia versus peribulbar anesthesia among the subjects undergoing phacoemulsification. Materials and Methods: Subjects included in the study were conveniently assigned into either peribulbar group (Group P, n = 100) and topical group (Group T, n =100). Group P received 4-5 mL of local anesthetic (equal amounts of 2% xylocaine and 0.5% bupivacaine) into peribulbar space with 1 inch 25-gauge needle. Group T, received 0.5% proparacaine eye drops instilled every 5 minutes half an hour before surgery. No sedation was given. All the patients under went phacoemulsification with IOL implantation. A four-point verbal pain scale was used for analgesia. Patients were asked to grade the pain during different stages of surgery. Akinesia was also assessed on four-point scale.
