Can femtosecond laser surgery in Wuhan Union Medical College Hospital be completely cured?
In recent years, with the continuous development of medical technology, laser surgery as a safe, fast and effective treatment method is widely used in the field of ophthalmology. As one of the advanced technologies, femtosecond laser surgery in Wuhan Union Medical College Hospital has attracted much attention. However, people have some doubts about whether femtosecond laser surgery can be completely cured. This article will elaborate the curative effect of this operation from different aspects.
Operation principle and process
Femtosecond laser surgery is to use the characteristics of ultra fast laser to precisely cut the cornea to change the curvature of the cornea, thus correcting vision problems. During the operation, the doctor peels off the corneum layer by layer through the laser, cuts the cornea in the inner layer cells, and then forms the required curvature in the inner layer of the cornea. The whole process is precisely controlled to ensure the safety of the operation.
Femtosecond laser surgery is mainly applicable to patients with myopia, hyperopia, astigmatism and other refractive errors. By adjusting the shape of the cornea, the operation can focus the light on the retina normally, so as to improve vision problems.
Cure effect
Femtosecond laser surgery is widely recognized for its therapeutic effect in correcting vision in ophthalmology. Through surgery, many patients can significantly improve their vision after surgery and get rid of the trouble of relying on glasses or contact lenses.
However, it should be emphasized that femtosecond laser surgery cannot be called a complete cure for refractive problems such as myopia, hyperopia or astigmatism. The operation only changed the shape of the cornea so that the light could focus on the retina normally, but it did not cure the refractive problem of the eye. Therefore, regular reexamination and adjustment are still required after surgery to ensure stable vision.
In addition, the curative effect of the operation is also related to the individual condition of the patient. For patients with high degree or other eye problems, multiple operations or other treatment methods may be required after surgery. Therefore, when considering the feasibility of surgery, doctors will make a comprehensive assessment according to the specific conditions of patients.
Operation risks and precautions
Although femtosecond laser surgery has been widely used, the surgery itself still has some risks. The operation may cause complications such as dry eyes, infection and corneal scar after the operation. Therefore, the patient needs to receive a detailed eye examination before the operation and follow the doctor's instructions for preoperative preparation.
During postoperative recovery, patients need to follow the precautions given by the doctor, such as avoiding strenuous exercise, not rubbing eyes, etc., to avoid injury to the surgical site. At the same time, regular reexamination is also an important link to ensure the effect of surgery, and any possible complications should be found and handled in a timely manner.
In general, femtosecond laser surgery is a safe, fast and effective ophthalmic surgery method, which can significantly improve vision problems. However, it needs to be emphasized that the surgery is not a complete cure for the refractive problem of the eyeball, and the patient needs to continue to have regular reexamination and adjustment after the surgery. In addition, surgery also has certain risks. Patients need to receive detailed examination before surgery, and follow the doctor's guidance for preoperative preparation and postoperative care.
