Currently, there is no way to do a second surgery for full femtosecond laser surgery, but procedures such as semi-femtosecond laser surgery and excimer laser surgery can be done if the cornea condition allows it. Full femtosecond laser surgery is a common surgical procedure for the correction and treatment of myopia, astigmatism and other diseases, with the advantages of less trauma, faster recovery, better comfort, higher safety and so on. However, after full femtosecond laser correction surgery, it is not possible to have secondary laser treatment. Full femtosecond myopia correction surgery is usually suitable for adult myopic patients and requires that the patient’s myopia has been stabilized for more than one year before the surgery, so that it is easy to maintain a stable refractive state after the surgery. It is recommended that patients undergoing full femtosecond surgery follow the doctor’s instructions, have regular checkups, and seek prompt medical attention when discomfort occurs.
