Operation process of femtosecond surgery in Wuhan People's Hospital
Wuhan People's Hospital is a professional ophthalmic hospital with an experienced team of ophthalmologists. In this hospital, femtosecond laser surgery has become the mainstream surgical method to correct myopia. Next, we will elaborate on the operation process of femtosecond surgery in Wuhan People's Hospital from four aspects.
1. Pre operation preparation
Before the femtosecond surgery, the doctor will conduct a detailed preoperative evaluation after the preliminary examination. This includes a comprehensive examination of the patient's eyes to ensure that their eyes meet the conditions for surgery. The doctor will also give preoperative guidance to patients, informing them of preoperative contraindications and relevant information about surgery.
Before surgery, patients need to have a general examination to ensure that they are in good health and that there are contraindications that cannot be operated on. At the same time, doctors will also measure the patient's eye data in detail, such as corneal curvature, aqueous humor depth, etc., in order to provide accurate data for surgery.
After all the preoperative preparations are completed, the patient needs to sign the informed consent form and enter the operating room under the guidance of the doctor.
2. Anesthesia and eyeball fixation
After entering the operating room, the doctor will perform local anesthesia to ensure that the patient will not feel pain during the operation. Usually, the doctor will drop anesthetic eyedrops and let the patient close their eyes for a period of rest so that the drug can play its role.
After anesthesia, the doctor will use a special eye fixator to fix the patient's eyes in a stable position. This is critical to the accuracy of the operation to avoid the patient accidentally moving the eyeball during the operation.
3. Femtosecond laser correction
Femtosecond surgery uses laser technology to correct myopia. During surgery, doctors will use a non-contact laser to cut a thin and precise flap inside the cornea. This process is called keratectomy.
After the cornea is cut, the doctor will open the flap to expose the tissue below the cornea. Then, the doctor uses the laser to reshape the cornea and adjust its shape to a specific degree more suitable for the patient. This process is called corneal correction.
The whole process of femtosecond laser correction is very fast, usually completed in a few minutes. The doctor will adjust the operation parameters according to the patient's situation to ensure the accuracy and safety of the operation.
4. Postoperative nursing and recovery
After the operation, the doctor will carry out some simple postoperative care. This may include the instillation of antibiotics and anti-inflammatory eyedrops to prevent infection and alleviate eye discomfort.
Patients need to rest for a while after surgery so that their eyes can adapt to the changes after surgery. Usually, the patient will be able to feel a significant improvement in vision within a few hours. However, full recovery may take days to weeks.
After surgery, patients need to follow the doctor's advice for regular follow-up to ensure the stability and recovery of the surgical effect. The doctor will also give the patient some advice, such as avoiding intense eye movement, not rubbing the eyes, etc., to ensure the surgical effect.
summary
Femtosecond surgery in Wuhan People's Hospital is a safe and effective method for myopia correction. The operation helps patients to restore clear vision through accurate corneal cutting and correction. During the preparation and nursing before and after the operation, the doctor will provide careful guidance and care to ensure the success of the operation and the health of the patient.
Finally, when choosing femtosecond surgery, patients should fully understand the surgical process, and choose a regular hospital and professional doctors for surgery to ensure the safety and effect of surgery.
