Anesthesia, Local Clinical Trial
Official title:
Evaluation of Duration of Anesthesia and Patient Satisfaction After Retrobulbar Block Applied in Cataract Surgery
It is aimed to determine patient satisfaction (pain assessment during and after the operation) and the initial and total anesthesia durations of eye lid and globe anesthesia after administration of local anesthetic solution only in standard applied volumes (1.5-3 ml). No agents will be added to the local anesthetic agents used in the conventional retrobulbar block in patients who will undergo cataract surgery,
