Wuhan Hospital Femtosecond Surgery
In recent years, with the continuous development of science and technology, femtosecond laser surgery, as an accurate, safe and fast way to restore vision, has gradually been widely used in Wuhan hospitals. This article will elaborate on the femtosecond surgery in Wuhan hospitals from four aspects: technical principles, surgical advantages, surgical procedures and indications.
Technical Principles
Femtosecond surgery uses femtosecond laser technology. Its principle is to accurately cut the surface of the cornea through the laser beam, so as to change the curvature of the cornea and achieve the effect of correcting the diopter. Compared with the traditional laser myopia surgery, the femtosecond surgery uses a very short laser pulse time, which is only femtosecond level. Therefore, the surgery process is less harmful to patients and the recovery period is shorter.
Another technical principle of femtosecond surgery is to form a group of bubbles in the cornea through the laser beam, separate the cornea layer by layer, then cut through the laser beam, and finally re integrate the cutting part. This layered and separated operation method reduces the damage to the cornea and makes the operation process more safe and reliable.
Surgical advantages
Compared with traditional laser myopia surgery, femtosecond surgery has the following obvious advantages:
First of all, the heat generated during femtosecond surgery is very little, which can maximize the protection of corneal tissue, reduce the risk of complications caused by surgery, and greatly improve the safety of surgery.
Secondly, because the femtosecond surgery adopts a knife free and non-contact surgical method, patients do not need to worry about the infection risk caused by the surgical blade during the surgery, and the surgery process is more comfortable and reassuring.
In addition, femtosecond surgery can not only correct myopia, hyperopia and astigmatism, but also treat corneal diseases, corneal diseases and other eye diseases, with a wider range of treatment.
Operation process and indications
Femtosecond surgery is generally divided into three stages: preparation, operation and recovery.
In the pre operation preparation stage, the doctor will carefully check the patient's eye condition, including measuring refractive index, corneal thickness and other indicators, to develop a personalized treatment plan for the operation.
In the operation phase, doctors will use femtosecond laser equipment to cut and reshape the cornea. The whole operation process usually takes only a few minutes.
In the recovery stage after the operation, the patient needs to carry out eye care and use eye drops according to the doctor's requirements, and at the same time, visit again regularly to ensure the operation effect and recovery.
Femtosecond surgery is applicable to myopia, hyperopia and astigmatism patients over 18 years old, and the corneal thickness should meet certain standards. Before operation, patients need to receive detailed examination and assessment from professional doctors to ensure the safety and effectiveness of the operation.
Summary
As a safe and effective way of ophthalmic surgery, the femtosecond surgery in Wuhan Hospital uses femtosecond laser technology to achieve accurate corneal incision, thereby improving the diopter and restoring the patient's vision. Femtosecond surgery has more advantages than traditional laser surgery. The surgical process is safe and effective, and the recovery period is fast. It has a wide range of indications and can correct different types of vision problems. For people who need to correct their vision, femtosecond surgery is a choice worth considering.
