Local anesthesia in cataract surgery--a comparison of different methods.
Seven groups of thirty patients undergoing cataract extraction under local anesthesia were each given different combinations of local anesthesia. These varied from a maximum approach using supra-orbital, infra-orbital and facial blocks with Hyalase, orbital compression and pre-operative Acetazolamide down to a minimum group receiving purely an infra-orbital and supra-orbital block with a Lignocaine/Bupivacaine mixture. There was no significant difference in local analgesia or in the complication rates between the seven groups. The benefits of Acetazolamide and orbital compression remain doubtful. The use of Hyalase and of a facial block resulted in fewer complications and in better akinesia.
