Peribulbar anesthesia is currently considered the regional anesthetic technique of choice for various ophthalmic surgical procedures because of its effectiveness and low incidence of complications. Recent techniques have reduced the number of injections from two to one and are undergoing evaluation. To measure the efficacy and safety of the caruncular single injection peribulbar technique for various surgical procedures performed at an ophthalmic clinic in Popayan city, Colombia. Patients undergoing various ophthalmic procedures were included. The anesthetic technique used was based on a caruncular single peribulbar injection. The anesthetic agent used contained 0.5% bupivacaine 2.5ml, 2% lidocaine 2.5ml with hyaluronidase 7IU/ml. Patients were evaluated at 10, 15, and 20min. The motor functionality of the four extra ocular muscles and the upper and lower eyelid motor control was measured. 137 patients were included; 54% were females and 77% ASA II. 10minutes into the evaluation, 92% of the patients achieved an adequate level of anesthesia to proceed with surgery. 36 patients (26.3%) required a booster dose of an additional peribulbar injection. Twenty-two patients (16%) reported mild pain during the anesthetic procedure. There were four cases of chemosis (3%). Using the caruncular single peribulbar injection, most patients achieved an appropriate ocular block for multiple ophthalmic surgical procedures. As time elapses, this block becomes stronger and the incidence of complications is low. En la actualidad la anestesia peribulbar se considera la técnica de anestesiaregional de elección para diversos procedimientos quirúrgicos oftalmológicos debido a su efectividad y a su baja incidencia de complicaciones. Técnicas recientes reducen las 2 punciones a una sola y se encuentran en proceso de evaluación. Medir la eficacia y la seguridad de la técnica de punción única peribulbar caruncular para distintos procedimientos quirúrgicos llevados a cabo en una clínica oftalmológica en la ciudad de Popayán (Colombia). Se incluyeron pacientes sometidos a diversos procedimientos oftalmológicos. La técnica anestésica empleada consistía en una punción única peribulbar caruncular. El anestésico utilizado fue bupivacaína 0,5% 2,5ml, lidocaína 2% 2,5 ml con hialuronidasa 7UI/ml. Los pacientes fueron evaluados en los minutos 10, 15 y 20. Se midió la funcionalidad motora de los 4 músculos extraoculares y el control motor del párpado superior e inferior. Se incluyeron 137 pacien
