Full femtosecond introduction of Zhengzhou Provincial Hospital
Zhengzhou Provincial Hospital is a comprehensive hospital located in Zhengzhou, with advanced medical equipment and excellent medical team. Full femtosecond is an ophthalmic surgery technology provided by the hospital, which is widely applicable to a variety of diseases and cases. This article will elaborate on the full femtosecond technology from four aspects: the principle of surgery, applicable cases, advantages of surgery and postoperative effects.
Operation principle
All femtosecond surgery uses laser technology, which can precisely control the depth and shape of corneal cutting. During the operation, the laser irradiates the cornea with high energy pulse and high frequency to evaporate the irregular surface, so as to shape the cornea. Because the laser cutting speed is extremely fast, it is not necessary to use the blade to contact the eyeball during the operation, which reduces the risk of infection, dry eyes and other complications in traditional surgery.
The full femtosecond surgery also uses advanced fundus tracking technology to accurately track the tiny changes of the eyeball through the fundus tracking system, so as to ensure the accurate positioning of the laser during the surgery and improve the success rate and safety of the surgery.
Applicable cases
Full femtosecond surgery is applicable to a variety of ophthalmic diseases and cases, including myopia, hyperopia, astigmatism and presbyopia. For myopic patients, full femtosecond surgery changes the curvature of the cornea by removing part of the tissue on the corneal surface, thus improving the degree of myopia. For hyperopia patients, full femtosecond surgery can improve the degree of hyperopia by increasing the curvature of the cornea. In addition, full femtosecond surgery can also correct astigmatism by adjusting the shape of the cornea.
At the same time, full femtosecond surgery is also suitable for presbyopia correction in the elderly. By creating multifocal or multi-level corneal curvature, full femtosecond surgery enables the elderly to clearly see objects at different distances, reducing their dependence on glasses or contact lenses.
Surgical advantages
Compared with traditional cutting surgery, full femtosecond surgery has many advantages. First of all, full femtosecond surgery is a non-invasive surgery, which does not require the blade to contact the eye, reducing the risk of infection and dry eyes during surgery. Secondly, the full femtosecond operation is simple and fast, and the whole operation process usually takes only a few minutes to complete. In addition, the postoperative recovery period is short, and patients can quickly recover their vision and reduce postoperative discomfort.
Full femtosecond surgery also has a high degree of customization. According to the eyeball shape of each patient and different correction needs, doctors can accurately adjust the laser irradiation parameters in surgery to achieve the best surgical effect. Therefore, full femtosecond surgery is excellent in surgical accuracy and predictability.
Postoperative effect
After full femtosecond surgery, patients can often recover clear vision in a short time. Generally speaking, patients can experience significant visual improvement on the first day or even the night after surgery. About one month after the operation, the patient's vision will be further stabilized and can gradually achieve the best effect.
However, after full femtosecond surgery, patients still need to pay attention to postoperative eye hygiene and protection to avoid infection and other complications. Regular follow-up after surgery is very important, and doctors will make further assessment and adjustment according to the recovery of patients.
Summary
As an advanced ophthalmic surgery technology, full femtosecond surgery in Zhengzhou Provincial Hospital is widely used in the treatment of various ophthalmic diseases. The operation principle is scientific, and the operation is simple and fast. Compared with traditional surgery, full femtosecond surgery has many advantages, including non-invasive, customized and fast recovery. After surgery, patients are often able to quickly restore their vision and experience obvious effects. However, postoperative eye hygiene and regular follow-up are equally important to ensure stable and lasting surgical results.
