Femtosecond surgery is suitable for several degrees myopia in a hospital in Wuhan

Femtosecond laser surgery is a very advanced and effective ophthalmic surgery method, which is widely used in a hospital in Wuhan to treat myopia. However, this kind of surgery is not suitable for all myopia patients. This article will introduce the scope of application and precautions of this operation from several aspects.

Classification of myopia degree

The degree of myopia is one of the indexes to measure the degree of ocular ametropia. Generally speaking, the higher the degree of myopia, the more obvious the refractive error. According to international standards, myopia is divided into several grades: low myopia (- 0.5D to - 3.0D), moderate myopia (- 3.25D to - 6.0D) and high myopia (- 6.25D and above). Femtosecond surgery is mainly applicable to patients with moderate and high myopia.

For patients with low myopia, because their refractive error is slight, they can be corrected by wearing glasses or contact lenses. The operation risk is high, so femtosecond surgery is generally not recommended.

Operation process and precautions

Femtosecond surgery mainly includes three steps: corneal flap cutting, laser correction of refractive error and corneal flap restoration. The operation uses laser to cut the cornea accurately and correct myopia by changing the shape of the cornea. The operation process is minimally invasive and recovers quickly. Most patients experience little discomfort.

However, femtosecond surgery is not suitable for all cases. First, patients with low or high myopia may not be suitable for surgery. Secondly, patients with other eye diseases such as keratitis and cataract are generally not suitable for femtosecond surgery.

Before the operation, the doctor will conduct a detailed examination of the patient's eyes to ensure the applicability and safety of the operation. After the operation, the patient needs to carry out eye care and reexamination according to the doctor's recommendations to ensure the effect of the operation.

Summary

Femtosecond surgery in a hospital in Wuhan is suitable for patients with moderate and high myopia. For these patients, surgery is a fast, effective and safe method to correct myopia. However, surgery is not applicable to all myopia patients, and surgery is generally not recommended for low myopia patients. Before undergoing femtosecond surgery, patients need to perform a detailed eye examination to determine the applicability and safety of the surgery. Through correct surgery and postoperative care, patients can obtain significant vision improvement.
