How about the femtosecond ophthalmic surgery in Wuhan Army General Hospital?
Wuhan Army General Hospital is a comprehensive hospital located in Wuhan, Hubei Province. It has advanced equipment and technology to provide high-quality ophthalmic services for patients. Among them, ophthalmic femtosecond surgery, as a modern ophthalmic surgery technology, is widely used in the ophthalmic department of the hospital.
Principle and characteristics of femtosecond surgery
Femtosecond surgery, also known as femtosecond laser myopia surgery, is mainly used to correct myopia, hyperopia, astigmatism and other ocular refractive errors.
The principle of femtosecond surgery is to use laser to cut the formation of the cornea, change the curvature of the cornea, so as to achieve the purpose of correcting vision. Compared with traditional laser surgery, femtosecond surgery has higher accuracy and safety. Its characteristics mainly include the following aspects:
1. More accurate: Femtosecond laser can achieve higher surgical accuracy and change corneal curvature more accurately.
2. More safety: because the energy of femtosecond laser is very concentrated, the tissue around the eyeball will be less damaged and the risk is lower during the operation.
3. Faster: Femtosecond surgery can be completed in only a few minutes, and the postoperative recovery period is short.
Steps of femtosecond surgery
Femtosecond surgery includes the following main steps:
1. Pre operation evaluation: The doctor will perform eye examination on the patient to determine the applicability of the operation and predict the effect after the operation.
2. Anesthesia: Before the operation, the doctor will give the patient eye anesthesia to ensure that there is no pain during the operation.
3. Making corneal flap: use femtosecond laser to make a thin flap on the cornea, which is the first step of corneal layer stripping.
4. Layer stripping: The doctor gently opens the corneal flap, and then uses a femtosecond laser to remove a certain thickness on the cornea.
5. Laser correction: according to the patient's diopter, doctors use femtosecond lasers to locally adjust the cornea to achieve the effect of vision correction.
6. Postoperative care: After the operation, the doctor will carry out some necessary care and postoperative inspection for the patient to ensure that the patient's eyes recover well.
Advantages and precautions of femtosecond surgery
Femtosecond surgery has obvious advantages over traditional laser surgery:
1. Accuracy: Femtosecond surgery has higher accuracy in corneal cutting, which can better meet the needs of different patients.
2. Safety: Since femtosecond surgery has less damage to surrounding tissues, the risk of postoperative complications and complications is low.
3. Reversibility: Femtosecond surgery can adjust the cornea reversibly. If the patient's myopia degree changes again, it can be corrected by further surgery.
It should be noted that femtosecond surgery is not applicable to all people, and there are certain contraindications and risks. Therefore, before considering surgery, patients should be consulted and evaluated in detail to ensure the safety and effect of surgery.
summary
As a modern ophthalmic surgery technology, femtosecond surgery in Wuhan Army General Hospital is characterized by accuracy, safety and speed. The procedures of femtosecond surgery include pre-operative evaluation, anesthesia, corneal flap preparation, lamellar peeling, laser correction and postoperative care. Its advantages lie in accuracy, safety and reversibility. However, patients should fully understand the precautions and potential risks before surgery. The femtosecond ophthalmic surgery in Wuhan Army General Hospital plays an important role in solving the problem of ocular ametropia for patients.
