This study of 100 day case patients having cataract surgery under local anaesthesia compared patient acceptance of two peri-ocular techniques; a transcutaneous method and a transconjunctival method. A significant difference was found in relation to the pain felt on injection such that all peri-ocular blocks at our unit are now done via the perconjunctival route.
