Usually, there is no pain associated with myopia surgery and patients do not have to worry too much about it. However, the exact discomfort varies from person to person and is related to each individual’s sensitivity. Myopia surgery is laser surgery on the cornea, which is rich in nerve endings but has no blood vessels, and anesthetic drops are applied to the surface of the eye. Patients will experience slight discomfort, but no significant pain, and the procedure is short and can be completed in a few minutes. During the procedure, corneal cutting will be done and there will be a foreign body sensation or smell of burning during the cutting, which is a phenomenon caused by the laser burning the corneal tissue. Most patients will have a slight discomfort after smelling the smell and at the same time feel uncomfortable in their eyes subconsciously due to excessive tension, but it is not a painful sensation caused by the surgery. As long as the patient is able to cooperate with the surgeon and make the surgery go smoothly, the discomfort will gradually disappear about half an hour after the surgery. In order to reduce post-operative discomfort, the surgeon will advise the patient to rest with the eyes closed as much as possible after surgery to reduce external stimulation of the eyes. However, since any surgery is traumatic, very few patients may feel slight pain or subconjunctival hemorrhage after surgery, which is a normal postoperative phenomenon. Most patients will have pain relief within a short period of time. If pain is significant, painkillers can be taken as appropriate. Subconjunctival hemorrhage is usually absorbed and dissipated naturally in 2-3 weeks and will not affect the recovery of vision. If the pain is unbearable and vision is not significantly restored, prompt medical attention should be sought.
