Many myopic friends have heard of myopia surgery. Those who know more about it will know that myopia surgery is divided into laser myopia surgery and ICL lens implantation, and the surgical procedures are different. Not the same, suitable for different groups of people.
For most people, it is possible to meet the requirements of laser myopia surgery. At present, the more mainstream laser myopia surgery is full femtosecond and half femtosecond. The main principle of laser myopia surgery is to cut corneal tissue by laser. The higher the degree, the more cornea is cut, and the corneal curvature is changed by cutting to correct myopia. Therefore, laser myopia surgery requires corneal thickness.
Full femtosecond, as the name suggests, the whole process uses femtosecond laser, and does not need to make a corneal flap. The principle is to make a lens in the corneal stroma, The higher the power, the thicker the lens is, and a tiny incision is made to remove the lens, and the surgery is complete. Full femtosecond can correct myopia within 1000 degrees and astigmatism within 500 degrees. Its advantages are that the incision is small, the operation is more comfortable, the eyes can be used the next day after the operation, the postoperative dry eye rate is low, and the stability is good. Therefore, many people who have requirements for postoperative stability, such as athletes, art candidates, etc., will consider full femtosecond laser surgery.
How to choose myopia surgery? Hu Ming, president of Yantai Aier Eye Hospital, said: Although full femtosecond has some advantages, it has high requirements for patients’ eye conditions. In other words, the applicable population is narrower than other surgical methods. If the degree is too high, the corneal thickness is not enough, the dark pupil is large, and the astigmatism is high, all femtosecond laser surgery may not be performed. At present, different surgeries have their own advantages and disadvantages, and no one can replace each other, and there is no way to achieve rolling. When choosing a surgical method, a patient must first do a detailed preoperative examination, and then a professional ophthalmologist will give advice in order to know which surgical method is suitable for him.
