Therapeutic principle of full femtosecond surgery in Wuhan People's Hospital
Wuhan People's Hospital is a real hospital. They introduced full femtosecond laser surgery technology to solve eye diseases. All femtosecond surgery uses advanced laser technology, and has made improvements in the traditional surgical method of blade contact with the eye. This article will elaborate the treatment principle of full femtosecond surgery in Wuhan People's Hospital from four aspects: operation principle, treatment scope, operation process and postoperative recovery.
Operation principle
Full femtosecond surgery is to accurately depict corneal tissue through laser pulse without manual operation, thus achieving higher surgical accuracy. This technology can remove the irregular shape of the cornea and improve the refractive status in the treatment of eye diseases. Before surgery, experts will use the parameters such as corneal vertex distance (E), diopter (D) and vitreous length (L) to determine the surgical plan to achieve the best correction effect.
In surgery, the full femtosecond laser system will cut the cornea hundreds of thousands of times per second at a very high speed, and complete the entire surgical process in a very short time. When laser cutting, there is a special cooling device to protect the eyeball from damage. During the operation, the doctor will adjust the position and intensity of the laser according to the patient's condition to achieve the best correction effect.
Compared with traditional surgery, full femtosecond surgery has higher safety and accuracy. Because it does not need to touch the eyeball, there is almost no risk during the operation, and the patient's pain is significantly reduced.
Scope of treatment
All femtosecond surgery can be used to treat a variety of eye diseases, including myopia, hyperopia, astigmatism and presbyopia. According to the patient's condition and the purpose of the operation, the doctor will choose the corresponding operation plan. For example, for myopic patients, surgery will change the shape of the cornea by thinning the central part of the cornea, so as to achieve the effect of correcting vision.
At the same time, full femtosecond surgery can also be used to treat hyperopia and astigmatism. The doctor will make a corresponding operation plan according to the patient's eye structure and symptoms. After surgery, patients can usually improve their vision significantly.
Operation process
Before the full femtosecond surgery, the patient needs to have a comprehensive eye examination and communicate with the doctor about the purpose and effect of the surgery in detail. If the condition meets the operation conditions, the doctor will arrange the operation time.
On the day of operation, the patient needs to be sterilized and anesthetized on the surface of the eyeball. Anesthetics are usually in the form of eye drops, and local anesthesia is not required. During surgery, the doctor fixes the patient's eyeball on the operating table, and then uses the full femtosecond laser system for surgery.
The whole procedure usually takes only a few minutes. After the operation, the doctor will provide simple postoperative care for the patient and arrange the patient to return home for rest.
Postoperative recovery
After surgery, patients usually feel some burning and foreign body sensation in their eyes, and doctors will give corresponding drugs to alleviate the symptoms. In addition, patients also need to follow the doctor's advice, maintain eye hygiene and avoid friction. During the recovery period, patients need to visit again regularly to ensure the surgical effect and eye health.
In general, the full femtosecond surgery in Wuhan People's Hospital has achieved accurate treatment of eye diseases through advanced laser technology. The operation has high safety, short operation time and fast recovery speed, which can significantly improve the vision and quality of life of patients.
After the above detailed description of the principle of full femtosecond surgery in Wuhan People's Hospital, we can see that the surgery has high accuracy and safety, and has a wide range of applications. Through full femtosecond surgery, patients can obtain good correction effect, thus improving vision and quality of life.
