After full femtosecond laser surgery treatment, it is normal to see things blurred for a short period of time, but if it does not subside for a long period of time, it is abnormal. Full femtosecond laser surgery is a common means of correcting and treating myopia, in the early period after surgical treatment, because of the existence of postoperative inflammatory reaction, the cornea will have mild edema, at this time, the patient will feel that he/she can see things blurrily, but this situation usually disappears in about 2~3 days. If the patient has been recovering from surgery for a longer period of time and still has symptoms of blurred vision, this is abnormal and requires timely examination at the ophthalmology department of the hospital to see if it is due to scar formation within the corneal stroma, the presence of secondary glaucoma and other causes.
