Abstract

Intraocular procedures are performed under local anaesthesia with the use of topical anaesthetic eye drops or injections of local anaesthetic drugs into a subtenon, retrobulbar, or peribulbar blocks. A prospective analysis of peribulbar block anaesthesia using a 25 millimeter, 23 gauge needle for 150 patients undergoing intraocular surgery was taken into consideration because the goal of this study is to demonstrate the safety and effectiveness of this needle in peribulbar block anaesthesia for intraocular surgeries. The amount of anaesthetic agent required, the number of injections required to generate sufficient anaesthesia, the duration and beginning of the anaesthetic drug's effect, and the technique's problems were all examined. Intraocular surgeries included primary cataract extraction using phacoemulsification/manual small incision sutureless cataract extraction with placement of posterior chamber intraocular lens implantation, secondary intraocular lens implantation with scleral fixation intraocular lens/iris claw lens, evisceration of the eye with artificial prosthetic implants.
