Sub-tenons anaesthesia for ophthalmic procedures

Abstract

Sub-Tenon’s anaesthesia has become widely practiced throughout the UK. It is a very safe and reliable block and is very well tolerated by patients. It can provide adequate anaesthesia for a number of ophthalmic procedures ranging from cataract surgery to vitreoretinal surgery. The sensory component of the block is often very effective, however, total akinesia may not always be obtained. Significant complications are rare, but many patients will experience a degree of conjunctival swelling and heamorrhage.
