How reasonable is the degree of myopia surgery?

With the continuous progress of science and technology, myopic surgery has become an effective way for many myopic patients to improve their vision. However, when choosing whether to operate or not, the degree limitation problem is often the focus of attention. So, how much should the degree limit of myopia surgery be considered reasonable? Let's explore it in depth.

First of all, we need to make it clear that everyone's vision is unique, and there is no absolutely insurmountable degree limit. Generally, doctors will recommend that the operation only be applied to patients with stable degree, so as to ensure more reliable and lasting surgical effects. According to different surgical methods and doctors' experience, myopia surgery is often limited to - 10 degrees to - 1 degrees.

However, in some special cases, some advanced myopia surgery techniques may be suitable for patients with higher myopia. For example, advanced surgical techniques such as laser in situ keratomileusis (LASIK) and surface polishing (PRK) can correct higher myopia. These operations are usually applicable to patients with degrees above - 10 degrees, but doctors still need to make a comprehensive assessment according to the individual conditions of patients.

However, in addition to the degree, doctors also refer to the patient's age, eye health, corneal thickness and other factors to determine the applicability of the operation. Young people's corneas are still developing, and the risk of vision regression after surgery is relatively high. Therefore, adults over the age of 18 are generally suitable for surgery.

In addition, if the patient has other eye diseases, such as dry eye and retinal diseases, the risk of surgery will increase. For these patients, doctors may suggest seeking other methods to correct vision, such as contact lenses or glasses.

In addition, the degree is only one factor that determines the applicability of surgery. Patients' expectations and lifestyle are also important considerations in deciding whether the operation is reasonable. Although myopic surgery can significantly improve vision, it does not guarantee to completely get rid of the use of glasses or contact lenses. Therefore, if patients have high expectations for surgery or are unwilling to bear the risks of surgery, surgery may not be suitable for them.

In general, when determining the degree limit of myopic surgery, doctors need to consider the patient's individual conditions and surgical risks comprehensively. Patients with stable degree, appropriate age and good eye health are usually candidates for surgery. However, everyone's situation is unique, so before making a final decision, it is important to consult a professional ophthalmologist and make a decision based on the doctor's advice.
