Zhongshan Ophthalmology Department: Can refractive errors be corrected by surgery?
Ametropia is a common ophthalmic problem, which means that the eyes can not focus light properly, resulting in blurred vision. For many patients, wearing glasses or contact lenses has always been the preferred way to improve their vision. However, with the development of medical technology, the choice of surgical correction of ametropia has attracted more and more attention. The following will elaborate on the possibility of surgical correction of ametropia from four aspects: corneal refractive surgery, lens replacement surgery, myopia laser surgery and laser corneal refractive surgery.
keratorefractive surgery
Corneal refractive surgery is a common surgical correction method, which is mainly applicable to myopia and astigmatism patients. The principle of surgery is to change the curvature of the cornea through laser or cutting surgery, so as to achieve the purpose of adjusting the diopter.
During the operation, the doctor will first conduct a comprehensive examination of the patient's eyes to determine the applicability and risks of the operation. Then, the doctor will use laser equipment or surgical blade to adjust the corneal morphology. The operation is usually performed under local anesthesia. The operation time is relatively short and the postoperative recovery is rapid.
Corneal refractive surgery is a safe and effective method to correct ametropia, which has been widely used in ophthalmic hospitals around the world, including Zhongshan Eye Hospital and other well-known hospitals.
Crystals replacement surgery
Lens replacement surgery is a kind of surgical method suitable for older patients with ametropia. With the growth of age, the transparency and elasticity of crystals will decline, leading to problems such as myopia, hyperopia or astigmatism. Lens replacement surgery improves vision by implanting intraocular lenses to replace damaged lenses.
During the operation, the doctor will first conduct a comprehensive eye assessment and examination to determine whether the patient is suitable for intraocular lens implantation. The operation is usually carried out under local anesthesia, and the doctor will implant an intraocular lens at the eye incision to replace the original lens. The operation time is short and the recovery period is short.
Lens replacement surgery is a reliable surgical correction method, which meets the requirements of postoperative durability and stability. Some well-known hospitals such as Zhongshan Ophthalmology Department have provided such surgical services, which have helped many patients recover good eyesight.
Laser surgery for myopia
Laser surgery for myopia is a surgical method to correct myopia by changing corneal morphology with laser. This operation is suitable for patients with low myopia.
During surgery, doctors will use laser equipment to cut the cornea to change its curvature. The operation is usually performed under local anesthesia. The operation time is relatively short and the postoperative recovery is rapid.
Laser surgery for myopia is a safe and effective surgical correction method, which has been widely used in the world. Zhongshan Ophthalmology Department and other hospitals provide such surgical services, helping many myopic patients recover good eyesight.
Laser corneal refractive surgery
Laser corneal refractive surgery is a surgical method to correct myopia and astigmatism at the same time, which is suitable for patients with myopia and astigmatism at the same time.
During the operation, doctors will use laser equipment to cut the cornea, not only to change its curvature, but also to adjust the diopter. The operation is usually performed under local anesthesia. The operation time is relatively short and the postoperative recovery is rapid.
Laser corneal refractive surgery is an advanced surgical correction method, which can simultaneously improve myopia and astigmatism. Zhongshan Ophthalmology Department and other hospitals provide such surgical services, which have improved the vision problems of many patients.
Summary
Through the above several surgical methods, ametropia can be effectively corrected. Corneal refractive surgery, lens replacement surgery, myopia laser surgery and laser corneal refractive surgery are commonly used surgical correction methods. These operations have mature technology and rich clinical experience, which can provide safe and effective vision correction programs for patients.
However, prior to surgery, a detailed eye examination and assessment is required to determine the applicability and risks of surgery. The situation of each patient is different, and appropriate surgical methods need to be selected according to individual conditions. When selecting surgery hospitals and ophthalmologists, it is better to choose formal and well-known ophthalmic hospitals, such as Zhongshan Ophthalmology Department, to ensure the safety and effect of surgery.
In conclusion, surgical correction of ametropia is a safe and effective method, which can improve patients' vision problems. Through corneal refractive surgery, lens replacement surgery, myopia laser surgery and laser corneal refractive surgery, Zhongshan Eye Hospital and other hospitals have helped many patients recover good vision and improve the quality of life.
