Blurry eyes after full femtosecond surgery may be caused by drier eyes, corneal inflammation and corneal edema. 1. Dry eyes: As the peripheral corneal nerves will be temporarily cut off during TFT surgery, the reflex tear secretion will be reduced in a short period of time, so the patient’s eyes may be dry, and the blurring of eyes after TFT surgery may occur. 2. Corneal inflammation: Because the cornea is in a relatively fragile state after TFT surgery, when affected by trauma or other factors, corneal infection and inflammation will easily occur, and under the stimulation of inflammation, patients may experience blurred eyes after TFT surgery. 3. Corneal edema: Surgical stimulation can lead to corneal edema, which can also cause blurred eyes. When patients have blurred eyes after full femtosecond surgery, it is recommended to consult a doctor in time to determine the cause of the disease and then give the corresponding treatment.
