The probability of having a femtosecond after excimer surgery is relatively low and can only be determined after a detailed eye examination. First of all, if you have had a myopic surgery and then have a second myopic surgery, it is clinically called a second booster surgery. If you have had excimer surgery, the probability of having femtosecond surgery again is relatively low, because most people’s corneas are not very supportive of having two surgeries, and the second enhancement surgery is usually a superficial laser or semi-femtosecond surgery. However, whether a patient can have another femtosecond surgery needs to be decided according to the specific conditions of the patient’s eye, including the degree of myopia before the first surgery, the remaining thickness of the cornea after the first surgery, and so on, the most important thing depends on the corneal thickness of the eye. It is recommended that patients follow the doctor’s instructions for care after laser corneal surgery, have regular checkups, and seek prompt medical attention when discomfort occurs.
