Spinal anaesthesia. Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, is a form of regional anaesthesia involving the injection of a local anaesthetic into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
While topical anesthesia has its use, most surgeons prefer blocks for complex cataract cases A good general rule of thumb to follow when preparing an anesthesia regimen for a patient scheduled to undergo cataract surgery is that any patient who is a candidate for block anesthesia (peri- or retrobulbar) may also be a good candidate for topical anesthesia.
