Myopia is a common visual problem characterized by distant objects appearing blurry while nearby objects appear clear. The causes of myopia can be divided into two types: external factors and internal factors. External factors, also known as environmental factors, such as prolonged eye use, close proximity, improper posture, strong or weak lighting, and insufficient sleep, can all lead to myopia. And the internal factors include genetic and developmental factors. In order to correct myopia, people usually choose to wear frame glasses or contact lenses, and some people choose to wear corneal reshaping lenses, rigid oxygen permeable corneal contact lenses, and other methods to correct myopia. However, no matter which method is used, it is always difficult to completely get rid of glasses, which brings various inconveniences to life. Therefore, people are beginning to shift their focus to another option - myopia surgery, also known as refractive surgery. So, is myopia surgery safe? Can everyone undergo myopia surgery? What are the types of myopia surgeries? After years of development, myopia surgery is safe after standardized management of clinical guidelines. Before undergoing myopia surgery, professional ophthalmologists will evaluate the patient's suitability through detailed preoperative examinations, as well as carefully perform intraoperative procedures and regular postoperative follow-up visits to help the patient avoid risks to the greatest extent possible. Generally speaking, the degree of myopia is stable between the ages of 18 and 45. After excluding contraindications to the eyes and the whole body, myopia surgery can be safely performed. At present, myopia surgery is mainly divided into two categories. The first type is corneal surgery, which is commonly known as full femtosecond, half femtosecond, excimer laser, etc. By cutting on the cornea, a certain thickness of corneal tissue is removed, and the curvature of the cornea is changed to achieve correction of near sightedness. This type of surgery requires patients to have a myopia degree between 50 degrees and 1000 degrees, and astigmatism below 500 degrees. The second type of surgical method is lens implantation surgery, commonly known as ICL, PRL implantation, etc., which involves implanting an artificial lens into the eye to change the refractive system and correct myopia. This surgical method is more suitable for patients with high myopia or those with a thin cornea that is not suitable for corneal surgery. Overall, myopia surgery is a safe and effective method for correcting myopia that is suitable for the majority of the population. Before considering this type of surgery, it is recommended to go to a professional tertiary hospital for examination and consult an ophthalmologist. After understanding your eye condition and the suitability of the surgery, choose the most suitable surgical method for yourself. (Lai Xin She)
