The duration of blurred vision after full femtosecond surgery ranges from about 2 days to 2 weeks, and the duration of blurred vision is affected by the preoperative vision and individual recovery, etc. Full femtosecond laser surgery is a kind of corneal refractive surgery, which is prone to blurred vision for a period of time after the surgery. However, according to the preoperative vision, people with serious preoperative refractive errors usually have a longer duration of blurred vision after the surgery, which may take 1-2 weeks; and if the preoperative refractive errors are relatively mild, the duration of their blurred vision after the surgery is relatively shorter, which may take 2-7 days. The blurred vision time after full femtosecond laser surgery is related to individual recovery. Generally speaking, if you pay attention to eye care after surgery and avoid prolonged eye use, your recovery will be relatively good and you will be able to shorten the postoperative blurred vision period to a certain extent; if you don’t pay attention to eye care after surgery and let your eyes stay in fatigue for a long period of time, your postoperative blurred vision period will be relatively long. If the blurred vision period is too long after the full femtosecond surgery, you should go to the hospital in time to get a clear diagnosis, so that you can carry out the targeted treatment as soon as possible.
