How does half femtosecond surgery in Wuhan Tongji Hospital treat myopia?
As a professional ophthalmic hospital, Wuhan Tongji Hospital has excellent ophthalmic technology and equipment, and its half femtosecond surgery has achieved remarkable results in the treatment of myopia. Half femtosecond surgery is to correct myopia through laser technology. The following will elaborate on the operation principle, operation process, postoperative nursing and operation effect.
Operation principle
The half femtosecond surgery uses the excimer laser technology to carve the front surface of the cornea through the role of the laser to change the corneal diopter, so as to achieve the purpose of correcting myopia. During the operation, the laser will accurately remove part of the white film on the cornea, so that the corneal diopter can be changed, so that the eye's light focus can accurately fall on the retina, improving vision.
Excimer laser has the characteristics of high accuracy and adjustability. During surgery, it can be customized according to the patient's myopia degree and corneal thickness. At the same time, this technique has less corneal damage and shorter recovery period.
Operation process
Half femtosecond surgery is a very fast and safe operation, and the whole process usually takes only a few minutes. Before the operation, the doctor will conduct a detailed eye examination of the patient to determine the operation plan. Before the operation, the doctor will give the patient some anesthetic eyedrops to ensure the comfort of the operation process.
During the operation, doctors will use professional instruments to scan and locate the patient's eyes, and make point cutting on the corneal surface. Then, the patient needs to stare at a point, and the laser will automatically operate according to the parameters predetermined by the doctor to complete the carving of the corneal surface. During the whole process, patients only need to keep their eyes still without worrying about pain.
After the operation, the doctor will wear goggles for the patient and explain the postoperative precautions. The patient can go home to rest and take postoperative care under the guidance of the doctor.
Postoperative nursing and surgical effect
Postoperative care is very important. Patients need to clean their eyes and use eye drops in strict accordance with the doctor's requirements. Avoid external irritation to eyes, such as rubbing eyes, strong light, etc. In addition, during the recovery period after surgery, patients need to return regularly so that doctors can monitor the effect of surgery.
Half femtosecond surgery can usually achieve significant results in a short time, with a short recovery period. However, the treatment effect after surgery varies from person to person, depending on the degree of myopia and corneal condition of the patient. Generally speaking, half femtosecond surgery can effectively correct myopia within 500 degrees, and the correction effect is stable, and patients can significantly feel the improvement of vision.
Summary
Half femtosecond surgery in Wuhan Tongji Hospital has significant advantages in the treatment of myopia. The operation principle is scientific and reliable, the operation process is simple and fast, the postoperative nursing is strict and standardized, and the operation effect is obvious and stable. The operation not only improved the patient's vision and quality of life, but also freed the patient's eyes from the shackles of glasses and contact lenses. If you have myopia, half femtosecond surgery may be a choice worth considering.
