Bengbu Traditional Chinese Medicine Hospital femtosecond
Bengbu Traditional Chinese Medicine Hospital is a medical institution focusing on TCM diagnosis and treatment. In the field of ophthalmology, Bengbu Hospital of Traditional Chinese Medicine has introduced advanced femtosecond surgery technology to provide more accurate and safe treatment for patients. Femtosecond surgery is one of the most advanced corneal refractive surgery methods, which is widely used in the treatment of myopia, hyperopia, astigmatism and other refractive errors. The following will elaborate on the indications, surgical procedures, effects and precautions.
indication
Femtosecond surgery is suitable for patients with myopia, hyperopia, astigmatism and other refractive errors. Specific indications are:
1. Myopia: patients with mild to moderate myopia can choose femtosecond surgery, including - 1.00D to -10.00D myopia. Femtosecond surgery changes the curvature of the cornea, so that the focus position of light in the eye is changed from myopia to normal.
2. Hyperopia: patients with mild to moderate hyperopia can also choose femtosecond surgery for correction. Hyperopia refers to the poor ability of the eye to focus on distant objects. Femtosecond surgery can change the shape of the cornea to change the focus position of light in the eye from hyperopia to normal.
3. Astigmatism: Femtosecond surgery is also applicable to astigmatism patients. Astigmatism refers to the irregular shape of the cornea, which leads to the deviation of the focus position of the light in the eye and blurs the vision. Femtosecond surgery can correct the shape of the cornea to focus the light correctly.
4. Corneal curvature: Femtosecond surgery is also applicable to corneal curvature caused by myopia. Corneal curvature is a condition in which the cornea of myopic patients becomes thinner and curvature increases. Femtosecond laser technology can remove the tissue on the corneal surface and change the shape of the cornea, so as to achieve the purpose of correcting vision.
Operation process
Femtosecond surgery is generally divided into the following steps:
1. Anesthesia: Before the operation, the doctor will give the patient local anesthesia to ensure the smooth operation.
2. Eye fixation: The doctor will use the instrument to gently fix the patient's eye to avoid eye movement during the operation.
3. Laser cutting: Next, doctors will use femtosecond lasers to perform precise cutting on the cornea. The laser has fast high-energy output, small thermal damage area and precise cutting ability.
4. Corneal shape adjustment: through laser cutting, doctors can adjust the curvature and shape of the cornea in the patient's eyeball, so as to achieve the purpose of correcting vision.
The whole operation process usually takes only a few minutes, and the patient is basically painless.
Effects and precautions
Femtosecond surgery has the following advantages:
1. Obvious effect: the visual acuity of patients after surgery has improved significantly. Myopic patients can significantly reduce or no longer rely on glasses and contact lenses for daily life and work.
2. High safety: Femtosecond surgery only cuts the surface of the cornea during the operation, and will not damage the deep tissue of the cornea, so the risk is small and the postoperative recovery is fast.
3. High accuracy: Femtosecond surgery can accurately adjust the shape of the cornea through laser cutting, so as to achieve the goal of correcting vision.
Pay attention to the following points after operation:
1. Rest after surgery: Rest after surgery must be paid attention to, try to avoid overuse of eyes, and avoid watching TV, using computers and other activities that cause eye fatigue.
2. Avoid rubbing eyes: after surgery, patients should try to avoid touching the eyes, do not rub or wipe hard, so as not to affect the wound healing.
3. Use medicine according to the doctor's advice: After surgery, the doctor will prescribe relevant eyedrops or tablets, and the patient should use them correctly according to the doctor's advice, and at the same time, visit again regularly.
Summary
Femtosecond surgery in Bengbu Hospital of Traditional Chinese Medicine is suitable for patients with myopia, hyperopia, astigmatism and other refractive errors. The procedure includes anesthesia, eyeball fixation, laser ablation and corneal morphological adjustment. The operation has obvious effect, high safety and high accuracy. After operation, pay attention to rest, avoid wiping eyes, and use medicine according to doctor's instructions. Femtosecond surgery provides a fast and effective method for patients to correct their vision.
