Myopic laser surgery can be performed between 100 and 1100 degrees. In addition, astigmatism up to 600 degrees and farsightedness up to 600 degrees can also be operated. In China, femtosecond laser surgery is generally used, usually with full femtosecond laser surgery and half femtosecond laser surgery. The former has fast recovery and fewer complications but also has certain limitations, low-degree myopia is not the preferred treatment, full femtosecond can not be used to treat farsightedness and so on. If the conditions are not met, semi-femtosecond laser surgery is recommended for treatment. If the myopia is too high and the corneal thickness is too thin it may not be suitable for myopic laser surgery, and you need to choose the myopic surgery method of IOL implantation. So the specific type of laser surgery used is not the more expensive is the best, but must be based on the patient’s specific situation and needs to choose the most suitable surgical method.
