Pre-anesthesia is one of the most important steps for performing ophthalmologic surgery with controlled local anesthesia because it allows a specialist to evaluate and prepare the patient before the procedure to ensure safety.

The information obtained during the pre-anesthetic assessment will allow the specialist to make an accurate decision about the anesthetic technique to be used and the most appropriate perioperative care according to the patient's condition and the type of intervention that will be performed. In addition, the necessary data are collected to fill out the patient's medical history; evaluate the risks the patient will be subjected to during the surgical procedure; establish what medications will be used to optimize clinical status; the individual's level of anxiety, and the necessary measures are taken to manage anxiety, including administering pre-anesthetic medication. Also, it is determined if it is necessary to perform complementary exams.
