Zhongshan Ophthalmology Guangzhou Manor - Can myopia be completely cured by surgery?
Myopia (also known as myopia) is a common ophthalmic disease, which refers to the condition that the vision is blurred when far away from objects, and the distant objects cannot be seen clearly. For myopia patients, glasses, contact lenses and other vision correction methods can only temporarily correct myopia, while surgery is considered to be a method that can completely cure myopia. Guangzhou Zhuangyuan is a well-known ophthalmic hospital, which provides various ophthalmic surgical treatments, including myopia surgery. However, there are still some factors that need to be considered whether myopic surgery can completely cure myopia.
Principle of surgical treatment
Myopia surgery mainly corrects the degree of myopia by changing the shape of the eyeball. The most common surgical methods include laser corneal refractive surgery (LASIK) and surface excimer laser (PRK).
LASIK surgery consists of two steps: first, ophthalmologists will use laser to create a thin flap like tissue on the cornea and fold it; Then, laser is used to reshape the central part of the cornea to correct myopia. PRK surgery is to irradiate the corneal surface directly with laser to change the curvature of the cornea, thus correcting the degree of myopia.
The principle of these surgical methods is to change the curvature or thickness of the cornea so that it can focus the light correctly, thus improving the patient's vision.
Whether the operation can completely cure myopia
Current surgical methods can significantly improve the vision of myopic patients. Many people do not even need to wear glasses or contact lenses after surgery. However, whether surgery can completely cure myopia still needs to consider the following factors.
First, surgery may not completely eliminate myopia. Some people may still have some degree of myopia after surgery. In addition, the degree of myopia tends to increase gradually in adolescence, and surgery can only correct the existing degree of myopia, which cannot prevent the increase of the degree.
Secondly, regular inspection and glasses registration are still required after surgery. Although surgery can improve vision, it takes time for corneal tissue to heal and recover. During this period, the doctor may recommend that patients wear glasses to stabilize their vision.
Finally, the risk of postoperative complications also needs to be considered. Although the surgical technique for myopia is very mature and the risk is very low, there are still possible complications, such as dry eyelids, infection, keratitis, etc. The doctor will make a detailed assessment of the patient before the operation to ensure the safety of the operation.
summary
Myopic surgery is a method that can significantly improve the vision of myopia patients, but whether it can completely cure myopia still has some limitations. The principle of surgery is to correct the degree of myopia by changing the shape of the eyeball, so that patients can better see distant objects.
However, surgery can not completely eliminate myopia, and can not prevent the increase of degree. Regular inspection and glasses registration are still required after surgery to ensure the stability of vision. At the same time, there may be some risk of complications after the operation, which requires detailed evaluation and guidance by doctors. Therefore, if the patient has myopia and considers surgical treatment, he/she should consult with a professional ophthalmologist to fully understand the efficacy, risks and suitability of the surgery.
