Most of the ophthalmic procedures are performed under local anesthesia as the patient is
often elderly and with diseases. This may increase the risk of morbidity and mortality under
general anesthesia. Different eye blocks have been practiced with great success. Moreover, it
is associated with less hemodynamic instability, less respiratory depression, better
postoperative pain relief, and less nausea and vomiting than general anesthesia. It is also
associated with a reduction in stress response, maintained oxygen saturation and
cardiovascular stability, in addition to the production of good akinesia and anesthesia
alleviating occulo-medullary reflexes, all make local anesthesia more superior and safe
technique.
