It is possible to run after cataract surgery, but it is not recommended in the early postoperative period, usually within one month. Cataracts are a common eye disease that causes vision loss, which affects normal life and usually requires surgical treatment. The principle of the surgery is to remove the cloudy lens inside the eye and replace it with a clear artificial lens to restore vision. In the early post-surgical period, the patient’s corneal incision site has not yet healed completely, and it is not recommended that the patient do strenuous exercise, so as not to affect the post-surgical repair. Generally about one month after the operation, the patient will recover better, at this time normal running and other physical exercise will not affect the eyes, the patient is allowed to run.
