Selection of myopic surgery
Nowadays, with the progress of science and technology, myopia surgery has become one of the effective methods to solve vision problems. However, for many myopic patients, in the face of numerous surgical methods, they often do not know which is better. So, let's learn about several common methods of myopia surgery and their respective characteristics.
Laser surgery
Laser surgery is one of the most common methods of myopia surgery, and is also the most widely used one at present. It uses laser to correct myopia by changing the shape of the cornea. Laser surgery has the advantages of significant correction effect, short operation time and fast recovery. At present, the common laser surgery includes femtosecond laser LASIK, femtosecond laser LASEK and ReLEx SMILE, which are popular in recent years.
Femtosecond laser LASIK surgery is to cut the cornea, fold it to one side, and then use the laser to evaporate the middle part of the cornea to achieve vision correction. The femtosecond laser LASEK peels off the corneal surface cell cover, and then uses the laser to evaporate the middle part of the cornea.
In contrast, ReLEx SMILE surgery is a relatively new laser surgery method. It can directly remove the corneal tissue for vision correction from the cornea by minimally invasive hole cutting in the cornea, so as to correct myopia. ReLEx SMILE surgery has the advantages of fast recovery after surgery, and it is not easy to have dry eyes after surgery.
Lens implantation
Lens implantation is another common operation for myopia. It achieves vision correction by replacing the lens of the patient's eye. Lens implantation is suitable for patients with severe myopia or other eye problems, such as senile cataract.
Lens implantation can be divided into intraocular lens implantation and ICL implantation. Intraocular lens implantation is to place the intraocular lens into the eye to replace the original lens, which is suitable for patients with insufficient corneal thickness. ICL implantation is to implant transparent intraocular lens with adjustable degree in the eye, which is suitable for patients whose corneal morphology is not suitable for laser surgery.
People suitable for myopia surgery
Although the surgical techniques for myopia are constantly improving, not all myopia patients are suitable for surgery. In general, people suitable for myopia surgery should meet the following conditions:
First of all, the degree of myopia of patients is stable and no longer increases significantly. If the degree of myopia is still growing rapidly, the surgical effect is likely to be affected.
Secondly, the patient's corneal thickness is sufficient. Since laser surgery requires evaporation of some corneal tissue to correct vision, insufficient corneal thickness may increase the risk of surgery.
Finally, the patient had no other serious eye problems. Serious iritis, keratopathy and other diseases may increase the risk of complications.
Summary
In general, the choice of myopic surgery should be based on the individual situation of the patient. Laser surgery is suitable for patients with light myopia and suitable corneal morphology, while lens implantation is suitable for patients with severe myopia or other eye problems. However, comprehensive eye examination and evaluation are still required before surgery, and professional doctors will give the most appropriate surgical choice.
In short, no matter which way you choose, myopic surgery is a safe and effective way to solve vision problems. It is hoped that myopic patients can fully understand their own situation and make wise choices under the guidance of doctors.
