Full femtosecond near surgery can be done on one eye. Full femtosecond surgery can be performed primarily by means of laser treatment, which can effectively correct refractive errors such as myopia and help restore vision. Normally, full femtosecond myopia surgery is performed to treat both eyes at the same time, but if there is a vision problem in only one eye, it is possible to have this surgery done on one eye as long as it meets the indications for full femtosecond surgery. After the full femtosecond myopia surgery, you need to pay attention to protect your eyes and local hygiene, and avoid rubbing your eyes with your hands to avoid inflammation and infection, which is not conducive to eye recovery. In addition, do not look at electronic products for a long time after the full femtosecond surgery, which will have a great impact on the vision recovery. If there are any symptoms such as eye discomfort after the surgery, you should consult the doctor for examination in time.
