Definition and principle of femtosecond surgery in Yancheng Eye Hospital
Yancheng Eye Hospital is a hospital specializing in femtosecond laser surgery, which is a modern high-precision ophthalmic surgery technology. Femtosecond laser is used in this operation. Corneal tissue is denuded layer by layer by irradiation of high-energy pulse laser beam, thus changing corneal curvature and correcting the problem of ocular ametropia.
The principle of femtosecond laser surgery is to use the laser beam to form a tiny bubble inside the cornea. The bubble will move quickly and form a corneal flap through the ultra fast pulse of the laser. Then, the doctor folded the corneal flap to one side and corrected the refractive error below the cornea with a laser. Finally, the corneal flap was restored to its original position and the operation was completed.
Femtosecond surgery is accurate and fast, with less damage to corneal tissue and short recovery time after surgery, so it is chosen by more and more patients.
The process and steps of femtosecond surgery in Yancheng Eye Hospital
The femtosecond surgery in Yancheng Eye Hospital is usually divided into the following steps:
1. Anesthesia: The doctor will use eyedrops to anaesthetize the patient's eyes before the operation, so that the patient can feel comfortable during the operation.
2. Preparation before surgery: The doctor will use special instruments to measure the patient's eyeball to determine the best parameters for surgery.
3. Corneal ablation: doctors will use femtosecond lasers to cut a thin slice on the patient's cornea to form a corneal flap.
4. Correction of refractive error: doctors will use lasers to correct the inner layer of the cornea to correct myopia, hyperopia or astigmatism.
5. Corneal reposition: After the operation, the doctor will restore the corneal flap to its original position and protect the patient's eyes with special nursing drugs.
Pain of femtosecond surgery in Yancheng Eye Hospital
Femtosecond surgery is usually painless because anesthetic eye drops are used during the operation. No matter corneal ablation or laser correction, patients will not feel obvious pain. Some patients may feel slight pressure or tingling in the eyes during the operation, but this feeling is temporary and will disappear soon.
After surgery, patients may feel discomfort in the eyes, such as dryness, pain or photophobia, but most of these discomfort can be alleviated through medication and eye care. Patients need to take medicine and eyedrops according to the doctor's instructions, and avoid strenuous exercise and rubbing eyes to help the eyes recover quickly.
Advantages and risks of femtosecond surgery in Yancheng Eye Hospital
The femtosecond surgery in Yancheng Eye Hospital has the following advantages:
1. High accuracy: Femtosecond laser surgery uses high-precision lasers, which can accurately control the surgical process and improve the success rate of surgery.
2. Fast recovery: because the operation has less damage to corneal tissue, the recovery time after the operation is relatively short, and the patient can quickly return to normal life.
3. Personalization: Femtosecond surgery can make personalized adjustment according to the eye structure and diopter of each patient to provide more accurate correction effect.
However, femtosecond surgery also has certain risks:
1. Postoperative infection: Any operation has the risk of postoperative infection, and patients need to follow the doctor's nursing guidance and return to see the doctor regularly.
2. Postoperative discomfort: some patients may have eye discomfort after surgery, such as dryness, pain or decreased vision, but these problems can be alleviated through appropriate nursing and drug treatment in most cases.
Before choosing femtosecond surgery, patients should fully communicate with doctors to understand the risks and effects of surgery and make wise decisions.
summary
The femtosecond surgery in Yancheng Eye Hospital is an accurate, fast and painless ophthalmic surgery technique. Through correct surgical procedures and postoperative care, femtosecond surgery can effectively correct myopia, hyperopia, astigmatism and other ocular refractive errors. Although some discomfort may occur during surgery, most of these problems are temporary, and most patients can recover good vision and eye comfort after surgery. Before choosing femtosecond surgery, patients should understand the specific process and risks of surgery and consult with doctors in detail.
