Abstract
The high turnover of day case surgery has been facilitated by a variety of local anaesthetic techniques that are available to the intraocular surgery. Local anaesthesia has become preferable to general anaesthesia due to improvement in techniques and instrumentation, most widely practiced of these are the peribulbar and retrobulbar anaesthesia.Peribulbar anaesthesia provides a high-quality anaesthesia for intraocular surgery with a very low risk of complications.Retrobulbar anaesthesia is a simple, effective and reliable method that has withstood the test of time.A mixture of lidocaine (lignocaine) and bupivacaine is the most frequently used local anaesthetic. Lidocaine is added to bupivacaine to reduce the latency to onset of block while bupivacaine significantly prolongs the duration of surgical anaesthesia.
