The most common reasons for having blurry seeing in the eyes after a femtosecond surgery are corneal edema after the surgery, as well as postoperative corneal inflammation or incorrect amount of correction. First of all, due to the surgical procedure of femtosecond surgery can cause some damage stimulation to the layers of the cornea, so much so that corneal edema, a temporary unstable state of the cornea, and consequently blurred seeing, may occur after the surgery. Secondly, the fragile state of the cornea after the operation may easily lead to corneal infection and inflammation when it suffers from trauma and other factors, which may also lead to blurred vision. As a result of a detailed pre-operative examination, the corneal thickness and other parameters of the degree of correction will be repeatedly checked, and it is rare to see the amount of correction is incorrect. There may also be a period of adaptation after surgery during which your vision may be blurred. It is recommended that you have a review of your post-operative blurred vision in order to detect pathologies such as infection and inflammation, and to take appropriate measures.
