What degrees of full femtosecond surgery is suitable for Grade A hospitals?

Full femtosecond laser myopia surgery is a high-tech method to treat myopia. The Second Grade A Hospital is a real hospital, which provides full femtosecond surgery services. However, not all degrees of myopia are suitable for full femtosecond surgery, so what degrees of full femtosecond surgery are suitable for Grade II hospitals? This article will elaborate on the operation principle, indication, postoperative effect and preoperative evaluation.

Operation principle

All femtosecond surgery uses laser technology to thin the cornea and form an accurate thin corneal flap on the corneal surface. During surgery, the laser can precisely cut the depth and shape of the cornea through computer control, and then implant intraocular lens suitable for the patient's degree under the thin flap. This kind of operation does not need to cut the cornea, so it is less traumatic to the patient and can recover quickly.

However, due to the limitation of the surgical principle, full femtosecond surgery may not be applicable to some patients with high degrees or abnormal corneal curvature. At this time, other surgical methods can be considered.

indication

The full femtosecond surgery in the second class hospital is applicable to myopic patients whose degree is within the range of - 8.00D to -1.00D. Among them, those with degrees between - 8.00D and - 6.00D belong to medium high myopia, and those with degrees between - 6.00D and - 1.00D belong to low myopia. For patients with high myopia whose degree exceeds - 8.00D, due to the limitation of surgical principle, other treatment methods may be required.

In addition, full femtosecond surgery is also suitable for patients with normal corneal curvature. For patients with abnormal corneal curvature, other treatments or corneal treatment before surgery may be required to meet the surgical requirements.

Postoperative effect

Patients in Grade II hospitals can usually recover their vision in a short time after full femtosecond surgery. The specific recovery time varies from person to person, and gradually recovers within hours to days after the operation. After surgery, patients need to pay attention to avoiding eye irritation behaviors such as strenuous exercise and eye wiping, so as not to affect the surgical effect.

The visual effect after surgery is usually lasting, but not all patients have the same surgical effect. Some patients may need to undergo recent additional surgery or wear appropriate glasses and contact lenses to maintain good vision. Before the operation, the doctor will make a detailed assessment of the patient and inform him of the possible effect after the operation, so that the patient can make a wise decision.

Preoperative evaluation

Before the full femtosecond surgery in the second class hospital, the doctor will conduct a comprehensive evaluation of the patients to determine the surgical indications. This includes checking the patient's corneal thickness, curvature, degree, and other eye conditions. Comprehensive preoperative evaluation can ensure the safety and effectiveness of surgery.

At the same time, preoperative evaluation also includes the evaluation of the patient's eye health to exclude the impact of other eye diseases on the surgical effect. If there are other eye diseases, the doctor may need to perform other treatment or surgery on the patient.

Summary

In general, the full femtosecond surgery in the Second Class A Hospital is suitable for myopic patients whose degree is in the range of - 8.00D to -1.00D and whose corneal curvature is relatively normal. The visual effect after surgery is usually lasting, but individual differences exist. Before the operation, the doctor will conduct a detailed assessment of the patient to ensure the safety and effectiveness of the operation. Preoperative evaluation is an important step to ensure the success of surgery.
