How long after optic nerve damage can vision still be restored through surgery?
Generally, if the optic nerve is damaged, recovery through surgery is still possible within 1 to 7 days after injury. If discomfort symptoms occur, it is recommended to seek timely treatment at a regular hospital. Detailed analysis is as follows:

When optic nerve damage is caused by acute compressive factors and the duration of injury is very short, there is a higher possibility of recovery through surgery within one day. For example, fractures of the optic canal or displaced bone fragments caused by head trauma may directly compress the optic nerve, but the nerve fibers have not yet undergone irreversible necrosis. At this time, timely decompression of the optic canal via endoscopic assistance and intraoperative neurophysiological monitoring to confirm that conduction function has not been completely lost may lead to rapid restoration of light perception or basic vision after surgery.
If the optic nerve damage results in mild contusion or ischemic changes, and surgery is performed within 7 days after injury, partial functional recovery may still be possible. For example, intrasheath hematoma or mild edema caused by trauma may not directly sever the nerve fibers, but prolonged compression could lead to secondary injury. In such cases, surgical intervention should include hematoma removal, sheath release, and postoperative hyperbaric oxygen therapy to promote microcirculation reconstruction.
Maintaining good lifestyle habits and a positive mindset can help promote the recovery process. Avoid strenuous exercise and reduce eye fatigue and discomfort. Also, maintain good eye hygiene to prevent infections.
