As far as ophthalmic surgery itself is concerned, it usually only needs local anesthesia to meet the needs of surgery. However, it should be noted that local anesthesia can only relieve pain, but can not relieve the discomfort caused by local operation. Moreover, because of the surgical site, patients often need to keep their eyes open (or be opened by instruments), which may increase some patients' fear of surgery. So if you feel that you can't stand this situation, general anesthesia is recommended.
