Eye injections usually require anesthesia before the operation, and there is some discomfort, but the degree is acceptable. Eye injections are divided into sub-bulbar conjunctival injection, parabulbar injection, post-bulbar injection, intra-bulbar injection, etc. The operation of parabulbar injection and other operations may have a certain degree of pain, sub-bulbar conjunctival injection, intra-bulbar injection, etc. usually need to be anesthetized with surface anaesthesia before the operation, and the operation has a lower degree of pain, and post-bulbar injection is usually anesthesia before the eye surgery, and may have a slight pain at the beginning. Eye injections require a high level of skill on the part of the operator, and patients are advised to choose regular medical institutions for treatment. When the doctor carries out the operation, the patient should take the initiative to cooperate with the doctor to make eyeball rotation and other movements, so as to avoid accidents during the operation, resulting in damage to the patient’s eyeball causing vision loss.
