Myopic full femtosecond surgery has certain requirements on the degree of myopia, age of the myopic patient, eye condition, and general condition. The degree of myopia should be between 100 and 1,000 degrees, and the thickness of the cornea should be within the safe range. Myopic full femtosecond surgery requires corneal cutting, and the higher the myopia, the more cornea is cut away, so there are certain requirements for myopia, and there are also certain requirements for corneal thickness. The more suitable age for full femtosecond surgery is 18~45 years old. The myopia will be more stable after 18 years old adulthood, and presbyopia is likely to occur around 45 years old, so the choice of myopia surgery can’t achieve the purpose of removing the glasses, and there is no need for surgery. Eye conditions are mainly to exclude the possibility of dry eye, conjunctivitis, keratitis, glaucoma and other ocular pathologies, while systemic conditions are to exclude immune disorders, excessively high blood lipids, blood sugar and blood pressure. For myopic people, if there is a need for full femtosecond surgery, it is recommended that patients go to a regular hospital to improve the examination, under the guidance of the doctor to choose, not reluctant to surgery.
