Vision correction surgery is usually safe and effective for humans to correct their vision, but the results after vision correction surgery vary from person to person due to their individual constitution and condition. There are many types of vision correction surgeries, including femtosecond laser surgery, IOL implantation, and crystalline lens implantation for crystalline eyes. Currently, the most common surgical method used in vision correction is femtosecond laser surgery. All of the above methods are basically safe and effective for improving and correcting vision, but we cannot exclude a very small number of people who have poor postoperative results, which is related to the surgical program and personal situation. For people with normal myopia of less than 1000 degrees, femtosecond laser surgery is a safer and more effective surgical method, and most of the surgeries have a better prognosis if the surgical plan is correct and suitable, and the patient actively cooperates with the doctor’s treatment. For people with high myopia, such as myopia of more than 1,000 diopters, IOL implantation and IOL implantation in crystalline lens eyes are often used, which are also more effective. The specific surgical treatment plan will be formulated by the doctor after examination and diagnosis, taking into account the patient’s own situation.
