What degree of myopia does the femtosecond surgery in a hospital in Guangzhou apply to?
As a well-known ophthalmic hospital, a hospital in Guangzhou has provided a variety of myopia correction surgery programs, including femtosecond laser surgery. So, what degree of myopia does femtosecond surgery apply to? The following will elaborate on the treatment principle, scope of application, surgical effect and precautions.
Principles of treatment
Femtosecond laser surgery is a vision correction surgery based on laser principle. During surgery, high-energy laser can accurately cut the specific tissue of myopia cornea through accurate calculation and control, so that the corneal curvature can be changed, thus achieving the purpose of correcting myopia.
Compared with traditional laser surgery, femtosecond surgery is more accurate and safe. It uses ultra fast laser to create tiny bubbles in corneal tissue, and then gently remove them, avoiding possible thermal injury and pain in traditional surgery, and reducing postoperative recovery time.
Applicable scope of operation
Femtosecond surgery is applicable to myopic patients with different degrees of myopia. Generally, the applicable myopic degrees range from -1.00 to -10.00, belonging to moderate and high myopia. The expert team of a hospital in Guangzhou will tailor the operation plan according to the patient's individual conditions and eye examination results to ensure the operation effect and safety.
Femtosecond surgery is also applicable to patients with abnormal corneal shape, such as abnormal corneal topography, weak cornea, etc. For these patients, femtosecond surgery can adjust the corneal curvature more accurately to achieve better correction results.
Surgical effect
After years of clinical practice, experts from a hospital in Guangzhou have proved that femtosecond surgery has achieved good results in the treatment of myopia. After surgery, the naked eye vision of patients has improved significantly, and most patients can achieve a vision of more than 1.0. After removing glasses or contact lenses, they can also live and work normally.
Moreover, femtosecond surgery has the characteristics of long-term stability. After surgery, the corneal morphology and vision correction effect were stable, and there was almost no deterioration of the correction effect. Patients only need to have regular eye examinations and reexaminations, and maintain good eye hygiene habits, then they can maintain good vision for a long time.
matters needing attention
Although femtosecond surgery has many advantages, it still requires patients to conduct a comprehensive eye examination before surgery, and fully understand the risks and precautions of surgery. Various corneal diseases, eye inflammation, glaucoma and other conditions may affect the surgical effect. Patients should inform the doctor in advance and take appropriate treatment.
In addition, postoperative care and reexamination should be carried out according to the doctor's instructions after the operation to avoid the conditions that are likely to cause corneal damage such as strenuous exercise and water activities. During the recovery period after surgery, patients should do a good job of eye cleaning and protection, try to avoid contact with irritants and eye friction, so as to promote wound healing.
In a word, the femtosecond surgery performed by a hospital in Guangzhou is suitable for patients with moderate and high myopia ranging from -1.00 to -10.00 degrees. It not only has good results, but also has long-term stability. Before deciding on the operation, patients should have a comprehensive examination and consultation. After the operation, patients should follow the guidance of doctors for nursing and reexamination to ensure the best lasting effect of the operation.
